guessing you have a low draw short somewhere........try disconnecting a bat
tery lead (positive) over night and see if that saves the battery charge, i
f so, then you need to work your way out the systems to find the shorting w
ire/part.=C2- IMO

13.5v isn't enough to charge the battery.

Between charges it is probably discharging and sulfating....needs to be kept at
full charge all the time, with a trickle charger....once it gets a real low charge
level, damage is done.

I think you need to look at the alternator. 13.5 volts is too little to charge
a 13.2 volt system (6 * 2.2 volts per cell). Recommend 14+ volts charging.
