Anyone else using them? I purchased one two weeks ago because I thought my other battery was dead. Actually, it was, but so was my alternator. So I replaced that as well. When I brought the TS Exide battery home, I hooked it up to the charger just to check its state. Showed 80%. I thought no biggie, probably just been sitting on the shelf a while. So I charged it for two days on the trickle charge to 100%. Installed it and hooked up the charger to the system. Showed 14.3 volts running and 13.1 not running. All good. Fast forward to today. Have driven the car at least half a dozen times. Drove to work this morning, left and drove to doctors appointment. Came out one hour later...car would not even turn into over. WTF? Jumped right off. Drove back to work. Left for lunch fired right up. Came out from lunch fired right up. Went back to work. Left to work to pick up kids from school, fired right up. Drove to school turned off for 10 minutes...dead a door nail. WTF? Jumped right off and drove home. Got home and pulled in garage. Hooked up charger, 14.3 volts. Disconnected negative battery cable...kept running. Reconnected and turned off car. Dead as a door nail, but showed to be at 95% charge and around 12 volts. Put on rapid rate charge for about 10 minutes, fired right up. Any ideas? Bad battery?
