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

lift for about 3-4 min
they are all pretty new, with only 10 flights in them

not so far...

I have 4 batteries since last Nov. Two of them are E-flite. I only have an E-flite charger with CX2. I do not have this problem.

1. You may have a problem charge. It did not change up to full.
2. You may run the bettery too low before you charge.

Try the link I posted for you and let us know if it works.
