Exact battery I needed, fast shipping

Very good product but wanted more to keep Olight functional well into the future if they stop making this specialized battery.

Battery Junction had it in stock, was less expensive, shipped next day. Amazon and Olight store were both back ordered on this battery which is required for the S1R Baton II and III if you want a rechargeable. 5 stars!

Good to have a spare

This battery is used in Olight's rechargeable models, S1R Baton II and Baton 3, which require
the use of this cell. I preferred their S1 Baton, which had a similarly strong magnetic base, but could use the long shelf life, higher capacity CR123 primary Lithium and more standard 16340 Lithium Ion rechargeable cells. This cell is a proprietary mechanical variant that might not work in other brand lights that take 16340's.
It is a shame that the S1R Baton II is no longer offered, since it is a much more versatile design, especially for uses such as glovebox emergency light and bug out bag lights as well as EDC light.
Given that the S1R II and Baton 3 require this proprietary battery, I decided to get spares.

The only battery that'll do!

Baton 3 will ONLY use this battery, which is a little bit of a shame, but these are cheap so I have purchased 2 extra ones and I'll cycle through them to keep them all equalized and in good shape.
