another dead battery problem

[mgeist]

yesterday i picked up the fsr and charged my battery for 3 hours on 2 amp yesterday.

today i went to try and unlock the doors and yes once again dead. ok this was my mistake i hooked up the battery without replacing the fsr

well i charged my battery again for 4 hours at 2 amp and when i tried starting my car everything shut off including lights. i went back and took off the negative and then replaced it and the lights came back on.

ugh starting to get frustrated. any ideas? is this normal if the battery isnt fully charged (if thats the case im not sure)
