Review: Long Lasting - We have put this battery to the test and it is working fabulous! It's a great buy and top quality! I am very impressed with this item, along with how easy it is to install. As a family, we put our door to USE, always in and out not to mention all the pets who also set off the video camera recording. There's also a pick up box in the carport so those customers ALSO set off the video recording device. When I saw we TEST, we test to the MAX! Our battery which came with the Eufy was running down frequently, and needed to charge longer than overnight for us, which was a no go for me. Great to have the security of knowing what's happening at all times! If you're on the fence, don't be!
Review: Fits perfectly! - The replacement battery fits the lock perfectly, with no issues during installation. In terms of performance, it matches the original battery that came with the lock—reliable power, consistent operation, and no noticeable difference in responsiveness. Having a spare battery that’s fully charged and ready to swap in gives me peace of mind, especially since it means I won’t be caught off guard if the primary battery runs low. It’s a simple upgrade that adds convenience and ensures the lock stays dependable at all times. Well worth the price in my opinion.

### ⭐⭐⭐⭐⭐ Great Replacement Battery
*by B***R on January 3, 2025*

I got this hoping for the best and was pleasantly surprised. I wanted another battery for my Eufy lock so one can charge while the other one is in use. After over a year it’s still going strong. It may actually be out performing the Eufy original battery. I’d definitely get another one of these.
