SwitchBot Smart Lock Pro Rechargeable Battery

This is a rechargeable battery specifically for the Smart Lock Pro.
In my home, I was using rechargeable AA batteries, but the voltage was too low, causing frequent errors.
Also, I was troubled by the batteries draining quickly when left open during the summer.

Switching to this genuine battery, I wonder what I was using before? It barely drains at all.

Please try using it.
Please note that the box may have some damage from storage.
