Proprietary Battery For The Ages
December 23, 2020
Olight has designed a line of batteries to rival them all with this little powerhouse. This 2 watt hour delivers reliable performance over many other batteries in their size range, like the CR123A line which usually only packs 200-300mAh. The IMR16340 packs a whopping 550mAh into a similar form factor. However, it is a proprietary battery designed for the Olight S1RBatonII, so you must use this battery. Olight did it right though! A very impressive cell that performs much better than others in their size range.

A must for the Olight S1R Baton 2
December 7, 2019
This battery is a must when it comes to having a spare for your Olight S1R Baton 2. Having this spare battery means you donít have to be out of commission with the S1R Baton 2 due to the flashlight needing to be attached to the magnetic charging cable and plugged into a USB power source to charge the battery. The battery measures 34.4mm long.

I am happy with the purchase.

amazing power retention
May 14, 2019
This battery powers my Olight S1RII, and provides me with 1000 lumens in a compact package.
It recharges easily and will power a flashlight for a long time--amazing in such a small package.
