NASTIMA Security Rechargeable Battery Compatible with eufy S330 S230 S220 E330 Video Smart Lock 3-in-1 and Smart Drop, 10500mAh Li-ion Battery Replacement

Good deal , it works on eufy door lock E330

I am a huge proponent of Eufy security products, and I own multiple cameras, the Homebase 3, S230 lock, and the video doorbell. I had previously purchased a Eufy-compatible battery to have as a spare for my S230 lock. The problem was that it wasn't really compatible. It didn't properly fit where the battery is supposed to be.I tried again with this battery, and after an overnight charge via USB-C cable, I inserted the battery into the S230. It slid in as well as the original! The lock powered on with its familiar chime. I checked the battery level via the app and it showed 100% charge. So far so good!After a of normal use, I can't tell any different in the battery drain from this battery compared to the one that came with the S230. The only difference is the price which makes this a great buy.

This is the perfect backup battery to have on hand. It works perfectly and we haven’t had any issues. 10/10 recommend.
