Great little powerhouse.
"I bought this as a hot spare for my new Olight baton, works great, holds a charge well."











The Olight IMR 16340 Rechargeable Li-Ion Button Top Battery is an incredibly powerful, long-lasting cell specifically designed for use in high-drain flashlights. Featuring a potent Lithium Manganese Oxide (LiMn2O4) chemistry, this impressive battery delivers 3.6 Volts of dynamic power and is able to hold a significant charge of 550 mAh, powering your flashlight for an extended period of time. The specialized chemistry also allows the battery to discharge power at a rate of 2.75 Amps, significantly more than a typical Lithium Ion battery, allowing its host to generate significantly brighter outputs.

"I bought this as a hot spare for my new Olight baton, works great, holds a charge well."
"Need 2 batteries for my Olight flashlight. So I purchase these Olight batteries to pair with my flashlight. Works great together."
"This is a great special purpose rechargeable battery for the Olight S1R II. The high-drain capability allows it to provide bright light in the 'turbo' ultimate brightness setting. It recharges inside the flashlight, and provides long-life too."
"I love my Olight S1R, but it requires this specific type of rechargable battery. Decided I should have a spare. It works great, just like original. The power of this little battery puts out is very impressive & lasts a LONG time between charges. Especially if you normally use the lower lumen modes. It's suprising how long it will produce power & hold a charge."
"Purchased this battery as a backup for the one in my S1R II light. Put it in the light, charged it & checked. The light comes on & it holds the charge. In short: it does what a battery is supposed to do. Delivery was 1 day ahead of the predicted date."
"I used these units during so nights in the low 30s, I tested them 3 days later and show no drop in voltage."
"This chemical composition of this battery allows it to draw > 2A current continuously. This may not seem important, but in the case of S1 baton, the high mode (~ 500 lumens) draws a lot of power. When I used a regular 16340 battery, the light would cut off when switched to high mode in only a few seconds. It won't turn on again unless I remove the battery and put it back in. I tried two different brands of battery and the problem persisted. This was very annoying and I thought the light was defective! Then I realized it might be the battery's protection circuit that's shutting the light off. I ordered this high drain battery and the S1 now functions perfectly, no more shut-off problem!"
"The LMR 16340 is a great battery for the price it can't be surpassed."
