    • So far so good
Set name: 654065 2000mAh
Review Image by JD
Owned it for 2 months and so far so good. I used it in a custom E-Ink dashboard project. The battery arrived at 4.1V and after 6 weeks of sitting around waiting for me to finish my project it was at 3.97V.

A good replacement. I had a device that the battery wouldn’t recharge. This replacement fit in the compartment it was meant for and the connector was a good fit.
