Streamlight Stinger リチウムイオンバッテリー

Picked one up for my Stinger and it's been holding a charge noticeably longer than my old one, even after several months of use. Really glad I didn't cheap out on a generic alternative.

This battery lasts over three hours on high, which is a big step up from the older version I was using. The charge indicator light makes it easy to see when it's fully topped off.

Finally, my old Stinger feels like a workhorse again instead of a paperweight. The lithium ion holds a charge noticeably longer than the original, and it slipped straight into the holster without any fuss.
