Review for model:

I haven't tested exactly how long it lasts, but it was enough for (I think) about an hour of fun with a Chinese copy of the M300 flashlight. I think that's a good result. It lights up, charges normally. I have no reason to complain.

Works well, solid build quality, and performs as expected. The only downside is that Olight requires its own batteries; universal ones do not fit.

The battery works as it should, fits my Olight S10R flashlight. Charging without any problems. The capacity is sufficient for longer trips. So far, no complaints.

After a small modification involving removing the foil around the positive end, the battery fits the Olight S10R Baton III flashlight. Otherwise, charging does not work in the charger. The old battery had the entire top exposed. Shipping from militaria.pl was express as always, and the battery works great.

Good backup battery. It's a pity that rcr123a batteries have relatively low capacity, but that's not the manufacturer's fault, it's just the nature of these cells.

It works, but it's hard to comment on the longevity as I've used it too briefly. Bought for a Fenix flashlight. The original Fenix battery has 700mAh, this one has 650mAh; for now the difference is unnoticeable.

After a small modification involving removing the foil around the positive end, the battery fits the Olight S10R Baton III flashlight. Otherwise, charging in the charger doesn't work.

High-quality rechargeable batteries, a substitute for expensive batteries. Used in flashlights and motion sensors for a home alarm system. They last a very long time. I recommend them.

This battery is an excellent alternative to expensive CR123 batteries - one piece is about 11-13 PLN. A one-time expense together with the charger. In the case of the S1, it stays lit well over an hour.

Thanks to Rafał's opinion from 21.07.2022, I did not think that the money was wasted if we think about the battery for the Perun 2 mini. Without the modification described by Rafał, the battery does not charge in this flashlight. You need to remove the black cover and now everything works fine. Thanks, Rafał!

A battery is a battery, it does its job, i.e., it doesn't heat up, holds a charge as it should, a nice light green color (so says my Pink One), and has a respectable capacity. If needed, buy without hesitation.

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

Olight is a brand that has never let me down. Holds a charge for a long time and charges in a reasonable time, which are the most important parameters for me. Fits the S10 flashlight. I recommend it.

Olight battery fits the Perun 2 Mini headlamp. Together, they make a nice set. Headlamp plus spare battery. Delivery, as always, was lightning fast.

It's a battery like any other, does its job: doesn't heat up, holds charge as it should, pleasant lime color (so says my Rose), good capacity. If you need it, just buy it.
