i have 5 batteries for my cx2 that sat for a couple of months during
the rain and cold fully charged.
i went to fly my heli so i put 2 of my batteries on charge
then went to fly only to find out that the battery would only give my heli
lift for about 3-4 min
they are all pretty new, with only 10 flights in them

how do you bring them back to life??????
or are they toast????
some are e-flight , common sence, smc batteries

thanx
