What timing for this thread. I just killed a 4 month old $90 battery by an overcharging alternator, that is also 4 months old from Carquest.

Needless to say, not too happy right now.

Hopefully the alternator will be covered under the warranty. But odds are I’m at least out $60 on the price of a battery.
