My gte keeps killing batteries. I suspect I don't drive it enough to keep the battery up and after draining to completely dead two or three times, they don't seem to want to take a charge anymore at all. How many miles at what speed would it take say for instance to fully charge a battery that was at 50%? I was also thinking about getting a trickle charger just so the car will always be ready to go whenever I get the urge to boost, even if its been awhile. Anyone ever used one of these? Weather was absolutely beautiful here today and so I started to drive the gte to work but grrrrrrr, the battery was dead and I didn't have time to mess with it till I got home tonight.
