How long does fully charged backup battery stay charged?
These are Lithium-Ion (Li-Ion) batteries and have a self-discharge rate of approximately 5-10% per month at the very most so they should stay charged for months. I recharge my batteries on a monthly basis although sometimes I forget...never had any problems after two months or more of non-use. You should discharge them to about 1/2 if you are not going to use them for a while.
