omg, i thought this was only happening to me, got a 34 gtt, and the battery has carked it (although recently, its been better than before). i was having a power leak for a while. i get home from work at 6pm, and i start the car in the morning at about 8.30am. atm, the charge when i turn the key is about 11.4v, a while back, i would reach like 10, and sometimes under. sometimes, i would just barely start the car. leaving it for a couple days not driven will need a jump start. my prev battery was from nrma, and they replaced it with another one about 2 months ago. the old one was completely funked.
