POOVER 9V Battery Rechargeable 700mAh High Volume Li-ion Batteries 2 Pack with 9v Universal Battery Charger

Works great just put the battery in the charger and forget it and it will be ready to go when you need it

These batteries last long, charge well and I think theyre better than the bunny/copper brands by far.

Use 1 battery while charging 2nd battery. Easy and convenient

Will take a full charge.
