بطارية ليثيوم قابلة للشحن لـ Familock S3 وS3 Max

Installed this in my S3 Max and haven't touched the lock's power settings since—it just holds charge and keeps the motor snappy. The swap itself took under a minute, which was a relief. Feels like a solid drop-in replacement for the original.

The old battery in my lock kept dying at the worst moments, so this rechargeable one is a relief—it holds a charge noticeably longer and the lock runs smoothly without hiccups. Swapping it in took me under a minute, and I don't have to worry about buying disposables again.

Got this installed in about five minutes and my Familock S3 Max hasn’t dropped below full charge in two weeks of heavy use. The battery fits snugly with zero rattling, and it’s nice knowing the lock won’t die mid-week like the last one did.
