I'm thinking about buying a backup battery for when I'm unable to charge the battery for a long time.
now I want to have a full charged battery in my room and when I need it I bring it with me and use it.
but I'm scared if I don't touch it for 1 - 6 months the battery power will drop and I want a guruatee it's charged and not worry about bringing it with me and find out the power is gone because I haven't used it in a long time.
