  • Great small battery for multiple purposes
We had a small selfie ringlight that would never work unless it was plugged into its USB charger. After opening it, we saw the small battery had swollen. Though this battery was a tiny bit bigger (mAh and size), it worked just fine and now the light charges and auto-shuts off after being fully charged. If your project calls for a small battery pack, this is working great, so far! ... show more

  • A good battery, if you need this size
I wish that better size information had been included in the description. This battery was purchased for an experiment with very little space for the battery. This battery did not fit the space available. The battery quality is good, just slightly too big for my need. I did use it temporarily, but had to find a replacement that fit correctly. One was found locally. ... show more
