I have a crate of Sony, Canon and Nikon batteries that don't work. Even if you don't use them, they degrade over time to the point they won't hold a charge.

They have a little circuit board in them called a BMS that uses power even when the battery is not being used.

If you let it sit long enough without charging the battery will die and will not recharge.

The BMS will kill the Li-Ion battery in a safe way if it is not used ?
