The original battery in the car is about a month old and i took a new battery that I bought 2 months ago and stuck it in there as well. I have two identical batteries that have been purchased in the past two months and the car has killed both of them in a matter of minutes. I did charge the donor battery and had the same results; low cranking rpms with 350 amps at initial cranking and it kills the battery way to soon. also i charged the battery with my truck for 15 minutes at 2000rpms my volt meter on my truck was ready well over 15 volts when charging. that isn't enough to charge the battery?
