You didn't say much about your charger. If it is a cheap one-stage
"trickle charger", look no further. Go out and buy yourself a good 3-stage
float charger (you will pay about $50.00) and a new battery. Overcharging by a
few tenths of a volt can easily ruin a battery in the timeframe you mentioned.
As others have mentioned, it is also possible that you just got unlucky and got
a bad one.
