ok, so in the last 6mths i've internally cooked a die hard plat. agm and 2 y.t. optima's... but my factory battery run's my system fine? I have a 05 cobalt and upon further research found that the ecotec has some sort of voltage regulator that doesn't run 14.4, it adjusts to save gas, average about 13.8, is there a way to bypass the regulator or should i just run my stock battery? theres no way my stock battery should be better than these agms, and my alternator tested great...
anybody had this issue?
