Olight RCR 123A 650mAh 3.7V Rechargeable Battery

After a minor modification of the battery, i.e. removing the foil from the positive pole, it fits perfectly into the Olight S10R Baton III flashlight. Otherwise, you can't charge it in the charger. The previous battery had the entire top part exposed. The shipment from militaria.pl was as fast as always, and the battery works flawlessly.

Good replacement battery. The downside is the low rcr123a capacity, but that's characteristic of these cells, not the manufacturer's fault.

The battery works, but it’s hard to assess durability since I’ve had it for too short a time. For the Fenix flashlight – the original has 700mAh, this one 650mAh, so far I don't see any difference.

With a slight modification—removing the foil around the positive end—the battery fits the Olight S10R Baton III flashlight. Otherwise, the charging function doesn't work. The old battery had the entire top exposed. Fast shipping from militaria.pl, and the battery works great.

Good quality rechargeable batteries, a great alternative to expensive batteries. I use them in flashlights and motion sensors for alarms – they last a very long time. I recommend them.

This battery is a great solution instead of expensive CR123 batteries – about 11-13 PLN each plus a one-time cost of the charger. In the S1 it lights for well over an hour.

Thanks to Rafał's tips from 21.07.2022, I didn't consider buying a battery for the Perun 2 mini a waste of money. Without the modifications described by Rafał, the battery won't charge in this flashlight—just remove the black cover and everything works perfectly. Thanks, Rafał!

The battery is like any other, does its job: doesn’t overheat, lasts a long time, color is nice according to my partner, capacity is good. If you need one, just buy it without hesitation.

Many better flashlights now use 3V lithium batteries or 3.7V lithium-ion rechargeable batteries. A rechargeable battery is a better choice! Very reliable, I recommend it.

Olight is a brand I can always rely on. The battery lasts long and charges quickly—that’s the most important for me. It also fits the S10 flashlight. I recommend it.

Olight battery, fits the Perun 2 Mini headlamp. The set is practical: flashlight plus an extra battery. As usual, very fast delivery.

A battery like any other, does its job: doesn’t heat up, the capacity is good, the color is nice—as my Róża says. If you need it, go for it without hesitation.

A useful option as a backup power source—I always have an extra battery in my flashlight to avoid surprises when it runs out at the wrong time.

Great battery. It’s been working in my Olight flashlight for a long time and I haven’t noticed any decrease in capacity. Charges without any problems on a standard charger. I recommend it.

It's good to have an extra battery for the S1R—it’s very efficient when powering 900 lm, but the flashlight consumes a lot of energy. For trips, I recommend taking at least two batteries.
