The 10,000 mAh capacity is a lifesaver—I got a full second week of recording out of my smart lock before needing to swap it. This battery fits perfectly into my S330 and charges up fast with the included cable.
I swapped the factory battery for this one on my Smart Lock and instantly noticed the peace of mind from the extra 10,000 mAh capacity. It slid right in without any fuss and the lock’s been running nonstop for weeks. Definitely worth grabbing a second pack so you’re never stuck fumbling for a charge
Charging the door lock battery takes maybe two hours, and the 10,000 mAh pack lasts me a solid three weeks before I swap them out. Having a spare means I never have to rush the recharge, which is exactly what I needed for the smart lock setup.
