Olight makes most of the lights discussed here. Olight specs and regular prices come from its US product pages and user manuals as of September 2026; other brands' specs come from their own sites. We did not drop, crush or soak any light; every calculated figure is arithmetic on published ratings.
⚡ TL;DR
Durable flashlights are the ones whose maker publishes a drop height, a water rating and a charging design you can check. On those published numbers, the Olight Warrior Ultra is the pick when drops onto concrete are the risk (2 m rating), the Seeker Ultra for long shifts, and the iUltra for keys. The public FL 1 summaries list no crush test.
If you work on a site, a farm, a patrol route or under a truck, you have heard every durability claim on the box. Nobody publishes the same drop, crush and mud conditions for every light, and a higher price does not prove a light takes a fall better. This guide reads the ratings that do exist and turns them into numbers you can check.
This table compares the two strongest durable flashlights here on Olight's published ratings, so you can see where each one leads and by how much.
| Dimension (Olight rating) | Warrior Ultra | Seeker Ultra | Which is better | Difference |
|---|---|---|---|---|
| Rated drop height | 2 m | 1.5 m | Warrior Ultra | 0.5 m, a 33% higher rating |
| Energy at the rated drop (m × g × h) | 3.49 J | 3.24 J | Warrior Ultra | 0.25 J, about 8% more |
| Water rating | IPX8 | IPX8 | Tie | None |
| Battery energy | 18 Wh | 20.9 Wh | Seeker Ultra | 2.9 Wh, about 16% more |
| Sustained Turbo stage | 800 lumens for 162 minutes | 1,000 lumens for 150 minutes | Seeker Ultra | 200 lumens brighter, 12 minutes shorter |
| Weight with battery | 178 g | 220 g | Warrior Ultra | 42 g lighter, about 19% |
| Charging as listed | MCC3 magnetic cable | USB-C with holster, or MCC3 magnetic | Seeker Ultra | Two charging routes instead of one |
| Regular price (September 2026) | $139.99 | $169.99 | Warrior Ultra | $30 less |

Quick Answer: What Makes Durable Flashlights Durable?
Durable flashlights survive the three places lights usually fail: the lens and head, the electronics inside, and the switch and charging point. A useful spec sheet gives a rated drop height under ANSI/PLATO FL 1, an IP water rating, and a charging design that keeps grit out. A hard body metal helps with scratches but cannot fix a weak driver or a loose battery contact.
So shop in this order: a published impact rating in meters, the IP rating with both digits read, then how the light charges and locks. Only then compare lumens.
If you want to browse by type first, Olight's full range of flashlights sorts every light by form factor, and its tactical flashlights page groups the duty lights.
Durable Flashlight Ratings Side by Side: Drop, Water and Build
Of the five Olight lights compared here, four list a drop height in the user manual: 2 m for the Warrior Ultra and 1.5 m for the Seeker Ultra, Seeker 4 Pro and iUltra. The ArkPro Ultra lists no drop height on its product page or in its manual. Water ratings run from IPX6 on the iUltra to IPX8 on the three round lights.
This table lists the durability ratings exactly as Olight publishes them, with the edition of the standard each manual cites.
| Light | Rated drop | Standard cited in the manual | Water rating | Weight with battery | Battery | Body material as listed | Regular price |
|---|---|---|---|---|---|---|---|
| Warrior Ultra | 2 m | "ANSI/NEMA FL 1-2019" | IPX8 | 178 g | 18 Wh (5000 mAh 3.6 V) | O-Aluminum | $139.99 |
| Seeker Ultra | 1.5 m | ANSI/PLATO FL 1-2019 | IPX8 | 220 g | 20.9 Wh (5,800 mAh 3.59 V) | OAL | $169.99 |
| Seeker 4 Pro | 1.5 m | ANSI/PLATO FL 1-2019 | IPX8 | 205 g (Silver-Plated Bronze: 350 g) | 18 Wh (5000mAh 3.6V) | Aluminum Alloy | $139.99 |
| ArkPro Ultra | Not listed | Not cited | IPX7 | 120 g | 7.4 Wh (2,000 mAh 3.7 V) | OAL (O-Aluminum) | $129.99 |
| iUltra | 1.5 m | ANSI/PLATO FL 1-2019 | IPX6 | 20 g | 0.296 Wh (80 mAh 3.7 V) | OAL (O-Aluminum) | $29.99 |
Prices are regular prices for each page's default color: Navy Blue (Warrior Ultra), Olive Green (Seeker Ultra, iUltra), Matte Black CW (Seeker 4 Pro) and Amber Orange CW (ArkPro Ultra). The Seeker 4 Pro page lists two weights; the manual's 205 g covers the standard body.
The current standard is ANSI/PLATO FL 1-2025; all four rated lights cite the 2019 edition, and the Warrior Ultra manual uses the older "ANSI/NEMA" naming, quoted as printed.
What Does a Flashlight Drop Rating Actually Test?
A flashlight drop rating is the height from which a light, with its battery and accessories installed, is dropped onto concrete and must still work with no cracks or breaks. It is a pass-or-fail check on the test samples. The public summaries do not state the number of drops or their orientations, so a claim such as "30 drops" is a brand's own method, not the FL 1 number.
Streamlight's one-page ANSI/PLATO FL1 summary defines impact resistance as "The degree to which a portable light resists damage when dropped on a solid surface," and adds: "Dropped samples must not exhibit any cracks or breaks and must remain fully functional in order to pass the Impact Resistance test." Nitecore Singapore's guide to the FL 1 standard says the drops go "onto a concrete surface at the specified height with all intended accessories, including batteries, installed." The full standard is sold, not posted, so neither summary gives the count of drops or which faces hit the ground.
The current edition is ANSI/PLATO FL 1-2025. PLATO's summary of what changed names four principal areas: "short-duration elevated brightness, dust ingress testing, updated product markings and revised IPX8 water-resistance testing." It publishes no new drop height, drop count or surface, so compare a rating by its height and note the edition it cites. Our ANSI FL1 explainer covers the other five spec-sheet numbers.
Note: A drop rating says the test samples passed at that height. It does not promise survival after a hundred drops, a drop onto a steel edge, or a drop from higher up.
Rated Drop Energy: Why 1.5 m on a Heavy Light Still Counts
The energy a falling light carries into concrete is its mass times gravity times the drop height. On Olight's ratings, the 178 g Warrior Ultra at 2 m carries 3.49 J, and the 220 g Seeker Ultra at 1.5 m carries 3.24 J, about 93% as much. The 20 g iUltra at the same 1.5 m carries 0.29 J. Height alone hides that spread.
The formula is E = m × g × h, and the speed at impact is v = √(2 × g × h). We use g = 9.81 m/s², rounded from NIST's standard acceleration of gravity of 9.80665 m/s², and ignore air drag. The table is based on Olight's rated weights and drop heights, not measured.
| Light | Weight (kg) | Rated drop (m) | Energy at impact | Speed at impact | Share of the Warrior Ultra's energy |
|---|---|---|---|---|---|
| Warrior Ultra | 0.178 | 2 | 0.178 × 9.81 × 2 = 3.49 J | √(2 × 9.81 × 2) = 6.26 m/s (14.0 mph) | 100% |
| Seeker Ultra | 0.220 | 1.5 | 0.220 × 9.81 × 1.5 = 3.24 J | √(2 × 9.81 × 1.5) = 5.42 m/s (12.1 mph) | 93% |
| Seeker 4 Pro | 0.205 | 1.5 | 0.205 × 9.81 × 1.5 = 3.02 J | 5.42 m/s | 86% |
| iUltra | 0.020 | 1.5 | 0.020 × 9.81 × 1.5 = 0.29 J | 5.42 m/s | 8% |
| ArkPro Ultra | 0.120 | Not listed | Not calculated | Not calculated | Not applicable |
Three things follow. The Warrior Ultra's extra half meter is worth only 8% more energy than the Seeker Ultra's rating, because the Seeker Ultra is 42 g heavier. The iUltra's rating covers about one-twelfth of the energy. And the Warrior Ultra's sibling, the Warrior 3S, lists 1.5 m at 176 g, or 0.176 × 9.81 × 1.5 = 2.59 J. For about $20 more ($139.99 against $119.95, regular prices), the Warrior Ultra's rating covers 35% more energy.
Where the light lands and how the battery is held also change what breaks, so use this table to compare ratings, not to predict one fall.
How Far Do Real Job-Site Drops Exceed the Rating?
Many working drops start higher than 1.5 m. OSHA's general industry rule requires fall protection at 4 feet (1.2 m) and its construction rule at 6 feet (1.8 m), so work at those heights is common enough to be regulated. A light knocked off a 6-foot platform edge falls 1.22 times the height of a 1.5 m rating, and one dropped from a 3 m ladder twice it.
OSHA's general industry rule, 1910.28(b)(1)(i), covers an employee "on a walking-working surface with an unprotected side or edge that is 4 feet (1.2 m) or more above a lower level." The construction rule, 1926.501(b)(1), sets the line at "6 feet (1.8 m) or more above a lower level." We add two assumed heights: 1.0 m for a belt and 3.0 m (about 10 ft) for ladder work.
This table compares each height with the two rating levels; for the same light, the ratio is also the energy ratio.
| Fall height | Source | Speed at impact | Ratio to a 1.5 m rating | Ratio to a 2 m rating |
|---|---|---|---|---|
| 1.0 m | Assumed belt or pocket height | 4.43 m/s (9.9 mph) | 0.67 | 0.50 |
| 1.22 m (4 ft) | OSHA general industry trigger | 4.89 m/s (10.9 mph) | 0.81 | 0.61 |
| 1.83 m (6 ft) | OSHA construction trigger | 5.99 m/s (13.4 mph) | 1.22 | 0.92 |
| 3.0 m (about 10 ft) | Assumed ladder work | 7.67 m/s (17.2 mph) | 2.00 | 1.50 |
The practical line is 6 feet. Below it, all four rated lights are inside their ratings. At 6 feet, only the Warrior Ultra stays inside its rating, with 8% to spare. Above about 2 m, every light here is past its published number, so a lanyard or holster does more for durability than any body metal.
A dropped light also endangers people below. OSHA's 1926.501(c) says that when an employee is exposed to falling objects, "the employer shall have each employee wear a hard hat" and take further measures. Tether or holster lights when you work above others.
Tip: Holster the Seeker Ultra or Seeker 4 Pro before you climb. Both manuals say the light locks when you put it back in the holster while it is off, so it will not switch on in the holster if something bumps it.
Why Do Many Flashlights Work After a Drop but Flicker Later?
A light that still works after a drop can flicker later because the electronics and contacts take the shock, not the LED. The U.S. Department of Energy notes that with LED products "there is ample opportunity for the electronics to fail before the LEDs go bad." A cracked solder joint, a bent spring or a shifted battery can pass a quick check and fail days later.
Nitecore Singapore's FL 1 guide makes the same point about flashlights: "Occasional drops shouldn’t be an issue, but repeated stress can cause damage that may lead to erratic operation or failure."
This framework maps four common failure points to what a spec sheet can tell you, and to what Olight lists for the five lights here.
| Failure point | What usually goes wrong | What the spec sheet can tell you | What Olight lists for these five lights |
|---|---|---|---|
| Lens and head | Cracked or loose lens, dented bezel | Lens type; impact rating | TIR lens on the Warrior Ultra and Seeker 4 Pro; Seeker Ultra page lists a TIR lens and a "Tempered Glass Lens"; none listed for the others |
| Driver and solder joints | Flicker, dead modes, random shutoff | Only the impact rating | 1.5 m or 2 m on four lights; none on the ArkPro Ultra |
| Switch and battery contacts | Light turns on in a bag, or cuts out when bumped | Lockout mode; battery type | Lockout on every light here except the iUltra; holster auto-lock on both Seekers |
| Charging point | Grit or water in the port, corroded contacts | IP rating; charging method | MCC3 only (Warrior Ultra); USB-C holster or MCC3 (Seekers); USB-C or MCC (ArkPro Ultra); USB-C plug under a flip cover (iUltra) |
If a light acts up after a fall, our guide to a flashlight not working walks through the checks in order.
Does Body Material Change How Well a Flashlight Survives a Drop?
Body material changes how a flashlight looks after a drop more than whether it passes one. Olight rates its OAL alloy harder or stronger than 6061 aluminum, yet the OAL Seeker Ultra and the plain aluminum Seeker 4 Pro list the same 1.5 m drop rating. Harder metal resists dents and scratches; the electronics inside still decide whether the light keeps working.
Olight's wording varies by page. The Warrior Ultra page says "1.73× stronger than 6061," the Seeker Ultra page says "almost twice harder than standard 6061 aluminum," and the ArkPro Ultra page says "1.73x as hard as standard 6061 aluminum alloy." Hardness and strength are different properties, and Olight does not name the test. Our guide to aluminum flashlight material explains how alloy grade and anodizing type divide the work.
Wall thickness is not published for any of these lights, by Olight or by the other makers cited here. A thicker wall resists denting but adds weight, and weight adds impact energy at the same height. Without a wall figure, the drop rating is the build number you can compare.
Mud, Grit and Water: What IEC 60529 Covers and What It Leaves Out
IEC 60529 rates how well an enclosure keeps out solids and liquids, not how it handles mud. The IEC says the first numeral covers solid objects, from 0 to 6, "no ingress of dust," and the second covers liquids, from 0 to 9. Mud is water carrying grit. None of the five lights here lists a dust digit, so their ratings speak to water only.
The IEC's IP ratings page says the second numeral "rates the enclosure's protection against liquids and uses a scale from 0 (no protection) to 9 (high-pressure hot water from different angles)." The current publication is IEC 60529:1989+AMD1:1999+AMD2:2013, edition 2.2. Our explainer on IPX8 meaning covers the water digits in detail.
This matrix pairs each light's rating with its charging design and the maker's care notes.
| Light | Rating as listed | Charging as listed | Care note in the Olight manual | What to do after mud |
|---|---|---|---|---|
| Warrior Ultra | IPX8 | MCC3 magnetic cable | None on cleaning | Rinse grit off the charging contact first |
| Seeker Ultra | IPX8 | USB-C with holster, or MCC3 | None on cleaning | Clear the holster and contacts before docking |
| Seeker 4 Pro | IPX8 | USB-C with holster, or MCC3 | None on cleaning | Clear the holster and contacts before docking |
| ArkPro Ultra | IPX7 | USB-C or MCC | "Keep the charging port clean and dry." | Dry the port fully before you plug in |
| iUltra | IPX6 | Built-in USB-C plug | "Keep the charging port clean and dry." | Keep the flip cover closed until the plug is dry |
Two manual warnings apply to muddy work near the coast. The ArkPro Ultra manual says "Do not immerse the flashlight in seawater or other corrosive media as it will damage the product," and the iUltra manual gives the same warning. The iUltra manual applies its IPX6 rating to "the main body," and IPX6 covers water jets, not immersion, so do not rinse it by dunking.
Does a Lifetime Warranty Cover Drop Damage?
No. Olight's lifetime warranty covers defects, not accidents. Its warranty page lists "Damage caused by improper storage, accidents, or abnormal operating conditions" and "Cosmetic wear and tear caused by normal use" as not covered. A light that cracks after a fall from a roof is an accident, while a switch that fails under normal use is a defect Olight will inspect and repair or replace.
Olight's lifetime warranty and return policy (last updated June 3, 2026) gives flashlights and built-in rechargeable batteries a lifetime warranty for products purchased after 2023. It also excludes "Batteries that fail as a result of ordinary usage, aging, or natural capacity decline," and it gives holsters, clips, lanyards and tools no warranty.
Safety Limits: Never Crush, Cut or Open a Lithium Battery
None of the five lights here has a published crush or compression rating, and the FL 1 summaries cited above define no crush test, so treat "crush-proof" copy as unrated. Do not improvise a crush test yourself. Every light here runs on a lithium-ion cell, and the iUltra manual warns: "Do not dispose of the battery in fire, a hot oven, or by crushing or cutting it, as it may result in an explosion."
What to do after a hard hit depends on what you see. The U.S. Fire Administration's lithium-ion battery safety page says: "Stop using lithium-ion batteries if you notice an odor, change in color, too much heat, change in shape, leaking or odd noises." The EPA's used lithium-ion battery page adds: "If the Li-ion battery becomes damaged, contact the battery or device manufacturer for specific handling information." It also notes: "Not all batteries are removable or serviceable by the user."
That last line applies to the ArkPro Ultra, whose manual says: "Do not remove the battery or replace it yourself." If a built-in light has been crushed or runs hot, stop using it and contact Olight rather than opening it.
Safety note: The ArkPro Ultra has a green laser (Olight's page lists up to 5 mW; the series manual lists Class 3R and Class 1 versions) and a 365 nm UV light. Never point the laser or UV light at anyone's eyes, pets or aircraft. The manual warns: "Do not look directly at the light source or shine it into your eyes, as this may cause temporary blindness or permanent damage to your eyes."
Who Makes the Strongest Flashlights?
No single maker makes the strongest flashlights, because no standard ranks strength. The closest public measure is the FL 1 impact rating, and 2 m is the highest rating among the lights compared here: Olight's Warrior Ultra, Streamlight's Stinger 2020 and Nitecore's P20iX all list 2 m. They differ on water rating, weight and battery, which decides which is strongest for your job.
This table lists each maker's own published ratings; the Stinger 2020 page gives two weights, so both are shown.
| Light | Maker | Impact rating as published | Water and dust rating | Weight as listed | Source |
|---|---|---|---|---|---|
| Warrior Ultra | Olight | 2 m | IPX8 | 178 g with battery | Olight product page and manual |
| Stinger 2020 | Streamlight | 2 m | IPX7 | 350 g; also listed as 348.70 g | Streamlight Stinger 2020 page |
| P20iX | Nitecore | "Impact resistant to 2 meters" | IP68 (2 meters submersible) | 116 g | Nitecore P20iX page |
Only the P20iX lists a dust digit, and the Stinger 2020's IPX7 is the lowest water rating of the three. At 350 g, the Stinger carries almost twice the Warrior Ultra's mass into the same 2 m drop. For brand-level comparisons on warranty and spec disclosure, see our guide to the best flashlight brands.
How Long Do Flashlights Usually Last?
A good LED flashlight can last many years, but it wears out on three clocks: the LED, the battery and the seals and switch. The Department of Energy puts the useful life of good white LED lighting at 30,000 to 50,000 hours, so at an hour a night the LED is rarely what ends a flashlight's life. Batteries, drops and grit usually are.
The DOE's LED basics page says: "Good-quality white LED lighting products are expected to have a useful life of 30,000 to 50,000 hours or even longer." That figure is for general LED lighting, not a flashlight on Turbo, but 30,000 hours at one hour a day is 30,000 ÷ 365 = 82 years. Olight's manuals also say the light source "is not replaceable," so when it does reach its end, the whole light is replaced.
The battery is the clock you can plan for. This table counts full charges per year for common use patterns, based on Olight's rated runtimes, not measured.
| Light and use pattern | Rated runtime per charge | Full charges used per year |
|---|---|---|
| Warrior Ultra, Med 200 lumens, 1 hour a day | 13 hours | 365 ÷ 13 = 28.1 |
| Warrior Ultra, Turbo start, 10 minutes a day | 2.5 + 162 + 39 = 203.5 minutes | 3,650 ÷ 203.5 = 17.9 |
| Seeker Ultra, Med 300 lumens, 1 hour a day | 12.5 hours | 365 ÷ 12.5 = 29.2 |
| Seeker 4 Pro, Med 300 lumens, 1 hour a day | 11 hours | 365 ÷ 11 = 33.2 |
| ArkPro Ultra, Pure Flood Med 100 lumens, 1 hour a day | 13 hours | 365 ÷ 13 = 28.1 |
| iUltra, 80 lumens, 5 minutes a day | 50 minutes | 1,825 ÷ 50 = 36.5 |
Even daily use adds only about 18 to 37 full charges a year. Batteries still lose capacity with age and use, which is why Olight's warranty excludes "natural capacity decline." The Warrior Ultra and both Seekers use a customized 21700 cell, and each manual's first step is to unscrew the light and remove an insulating film from it. The ArkPro Ultra and iUltra have built-in batteries. For a light you plan to keep a decade, a removable cell is the easier fix.
Which Flashlight Do Navy SEALs Use?
We found no Navy or Department of Defense document that names a standard handheld flashlight for Navy SEALs. What you can check instead is whether a light publishes the ratings a hard-use buyer needs: an impact height, an IP rating, a lockout and a sustained output level.
Olight lists law enforcement among the uses for the Warrior Ultra, Seeker Ultra and Seeker 4 Pro, which describes a design target, not an issue contract. Treat "used by special forces" copy as marketing unless the page names the unit, the contract or the test.
Durable Flashlights by Job: Construction, Law Enforcement and Farm Work
Match the durable, rugged flashlight to the drop, the dirt and the charging you face at work. On a construction site, pick the highest drop rating you can carry. On patrol, pick a tail switch and lockout. On a farm, pick the battery that lasts through chores and a charging method that tolerates dirt.
This table sums up who should choose the Warrior Ultra and who should choose the Seeker Ultra, with the published number that decides it.
| If you... | Rugged flashlight to choose | Deciding number (Olight rating) |
|---|---|---|
| Work at heights near 6 feet or drop lights onto concrete | Warrior Ultra | 2 m drop rating against 1.5 m |
| Light up a barn, yard or engine bay for long stretches | Seeker Ultra | 1,000 lumens for 150 minutes; 20.9 Wh |
| Want a wall-mounted charging dock in a shop or truck | Seeker Ultra | Holster charges over USB-C and mounts with the bracket |
| Want the same holster system for less | Seeker 4 Pro | $139.99; 1.5 m and IPX8, same as the Seeker Ultra |
Construction and roofing. The hard part is height: a light set on a platform edge falls past most ratings. The Olight Warrior Ultra tactical flashlight ($139.99, regular price, September 2026) is "built to withstand 2-meter drops," is rated IPX8 and weighs 178 g. Its Turbo runs 2,500~800~250 lumens for 2.5 + 162 + 39 minutes, so plan around 800 lumens. Its limit: charging is by the MCC3 magnetic cable only, so keep the cable in the truck.
Law enforcement and security. Here the problem is getting light instantly without it switching on in a pocket. The Warrior Ultra's tail switch gives momentary Medium or Turbo in its default configuration, and holding the side switch for about 2 seconds from off locks it. If your department already standardizes on the Warrior 3S, note its 1.5 m rating against the Ultra's 2 m.
Farm, ranch and fleet shop. The hard part is long use with dirty hands. The Olight Seeker Ultra high-power flashlight ($169.99, regular price, September 2026) holds 1,000 lumens for 150 minutes after its 2.5-minute Turbo burst and runs 12.5 hours at 300 lumens. Its holster locks the light when you dock it switched off, and it mounts with the included bracket. Its limits: 220 g, and a 1.5 m rating. The Olight Seeker 4 Pro flashlight ($139.99, regular price, September 2026, Matte Black CW) shares the 1.5 m and IPX8 ratings for $30 less, with a plain aluminum body and 18 Wh.
Mechanics and pocket carry. The Olight ArkPro Ultra flat EDC flashlight ($129.99, regular price, September 2026) is 16 mm thick with a 1,700-lumen flood and 800-lumen spot. But Olight lists no drop rating for it, its rating is IPX7, and its manual warns against seawater. Use it for inspection, not ladder work. For keys, the Olight iUltra keychain flashlight ($29.99, regular price, September 2026) weighs 20 g with a 1.5 m rating, but it is IPX6 and runs 50 minutes. Its manual says to "Keep the product out of reach of children to prevent accidental swallowing," so keep it on an adult's key ring. Both the ArkPro Ultra and iUltra manuals also warn against storing the light "in a car where the temperature inside may exceed 60°C," so do not leave either on a dashboard.
Common Mistake: Survived the Drop Means Durable
Surviving one drop does not make a flashlight durable. A pass shows the light worked right after that fall, not that its driver, contacts and seals are unharmed. Durability is the sum of a rated drop height, a water rating, a covered charging point, a lockout and a replaceable battery, plus your habit of tethering the light. A harder body does not raise the drop rating, IPX8 does not mean mud-proof, and no FL 1 summary lists a crush test.
The habit that matters most is cheap: a lanyard, holster or clip keeps the light off the floor. If you are buying on a tight budget, our best budget flashlight guide weighs durability against price.
Your Durable Flashlights Checklist
Use this checklist to buy and keep durable flashlights on published evidence rather than box copy. Run it before you buy and again after any hard fall; every step ties to a published rating or a manual instruction.
- Find the drop height in meters and the FL 1 edition. Prefer 2 m if you work at or above 6 feet.
- Multiply weight in kilograms by 9.81 and the rated height to compare rating energy between lights of different weights.
- Read both IP digits. An X in the first place means dust and grit were not rated.
- Check the charging point: magnetic contact, holster dock or open port, and whether it has a cover.
- Learn the lockout on day one, and holster or tether the light whenever you work above others.
- After a hard fall, check for flicker, heat, odor or a change in shape, and stop using the battery if you see any of them.
- Keep the receipt and know the warranty line: defects are covered, accidents are not.
