akuma4u Posted July 12, 2020 Report Share Posted July 12, 2020 When buying an agm battery, which battery specs are most important? Cca hca ah? I was told ah is the main thing the higher the better. But then i was told its all about how many amps it can produce..the higher the better.. so should i be looking at the ah cca or hca??

Backwoods Posted July 12, 2020 Report Share Posted July 12, 2020 Will the battery only be a secondary battery or will it be your starting battery under the hood? If it's just a secondary battery, AH is what I'd be looking at. As it will be used for reserve capacity. Starting batteries need cranking amps, cold cranking/hot cranking. So CCA and HCA will play a bigger role. Singer 250amp Alt, Singer PCM bypass harness Titan8 Lithium Underhood safe BCI PWR-S5 Big 3 W/ dual runs of power/ground.
