Swapped this into my S330 lock without having to take the whole unit off the door, which was way easier than I expected. The 10,000 mAh capacity means I’m getting months between charges, and it’s nice not buying disposables again.

Bought this as a backup for our front door lock, and the 10,000 mAh capacity is reassuring—we've gone weeks without a recharge. Swapping it in takes about a minute, and it's nice not buying throwaway AAs every few months.

The swap is so easy I didn't even need to take the camera down—just popped the old battery out and slid this one in, took about ten seconds. It's charged up in a few hours and the 10,000 mAh has been running my smart lock without a hitch for weeks now.
