    • Solid battery replacement
Style: Button Top
My flashlight requires this unusual battery. It's nice that it's rechargeable, and seems to work very well. The product arrived quickly, and was packaged well. It is a bit of a generic product, with no information on the battery itself. Nonetheless, it fits the flashlight, charges as appropriate, and works as expected. ... show more

    • Brought my patio string lights back to life
Style: Button Top
I got these to replace the old batteries in a solar-powered rechargeable battery for some outdoor string lights. Battery life is a bit longer than the originals, so that's good.

    • These SUCK
Style: Flat Top
Wow these are the worst batteries I've ever tried. Don't hold a charge and barely work. Never thought I'd hate a battery, but these are TERRIBLE. I'd give zero stars if I could. Just frustrating, unreliable, and dumb. Dies in minutes.

    • I would not buy these again!
Style: Button Top
I bought these for a flashlight that was purchased from Amazon. They discharge rather quickly but they are still better than the batteries that came with the flashlight.
