My startes box battery is giving me problems, please help. This is my second battery in the starter the first one I charged at to high of a rate and ruined it the second I thought I did everything right but now it won't take a charge. So my question is do these batterys always go bad so easily and is there any way to recover a bad battery???

The battery is a Gel type 12volt sealed battery from Hangar 9. The last battery was bought new in May or June of this year it was fine for a while but I haven't raced for about 2 months now and the battery just sat, when i went to charge it the other day it didn't seem to take a charge.

The reason this realy bugs me is because in my flight box I use a motorcycle battery and have been for 2 years now with no problems what so ever, I know the batterys are different but similar so why do these sealed batterys go bad so easy???

Thank you for any help or comments.
