BCI group 48 (H6), rated at 615 cold cranking amps from the factory. Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side. ### How many CCA does a 2012-2013 Chevrolet Silverado 1500 need? At least 615 CCA. Going higher is harmless and helps in cold climates; going lower is how a vehicle that started fine in October stops starting in January. ### Does the 2012-2013 Chevrolet Silverado 1500 need an AGM battery? The factory battery is a conventional flooded type. AGM is a valid upgrade, but never downgrade from AGM to flooded. ### Where is the battery on a 2012-2013 Chevrolet Silverado 1500? Engine bay, driver side. ### Does a 2012-2013 Chevrolet Silverado 1500 need the battery registered after replacement? Factory battery is a flooded Group 48 rated ~615 CCA; replacements of 615-760 CCA are common. An H6 AGM drops in as an upgrade. Some heavily-optioned trucks came with a higher-CCA battery.
