eufy Rechargeable Battery for S330 3-in-1 Video Smart Lock, E330 Video Smart Lock, Smart Lock S230, Smart Lock E31 and Smart Drop

OEM battery, same battery life as the original one come with the eufy device, no more battery anxiety for your smartlock/doorbell cameras!

Perfect fit for my S230. I needed a backup battery when the original one needs to charge. This was perfect!

Took six hours to charge but lasts weeks when installed. Changing batteries is my simpler that charging the battery in the lock assembly.

So far so good!

The reason I have taken a star off of my rating is because eufy STILL fails to provide the information regarding what all this rechargeable battery is compatible with! Well, that was the case at the time of this review. For anyone who has the Video Smart Lock E330 though (Model # T8531), I can assure you that this rechargeable battery is compatible with it. Everything on the back of the battery that comes with that is identical to everything that's on the back of this battery. Except for where it says the date in the bottom right hand corner of the information sticker. But that's it.I also know that many people who got that E330 Video Smart Lock were a bit perturbed that there was no charging cable included to charge the battery with. And well, this rechargeable battery doesn't come with a charging cable either, lol. Hey, in my opinion that's a good thing. But if they are going to do that then they need to make sure they are clear about that.Anyway, no matter which of the video smart locks you have, this rechargeable battery is pretty much a must have. Especially considering that it takes 6-8 hours to fully charge. And just one more thing. I've noticed a lot of generic versions of these rechargeable batteries are for sale out on Amazon. But I wouldn't recommend using any of them. It's just always been a personal rule of mine to always use name brand when possible.

Great Product

I bought two of these and they work perfectly. They last about 4 months but because I bought 2 I don’t have to wait until one is charging. I just keep the spare one charged and swap it out when the other one is dead.

Battery life of the battery I got was easily a month or two which is more than enough for me. Takes seconds to install and swap out. Charges via USB C which is great. Functions perfectly. Did not know if I wanted to trust 3rd party brands so bought a OEM one and do not mind the few extra bucks spent.
