What is the Difference between Conventional and Absorbed Glass Mat AGM Batteries?

Cold Cranking Amps (CCA)

Cold cranking amps (CCA) measure a battery’s ability to start an engine in cold temperatures. The replacement battery should have a similar or higher CCA rating than the H6 battery to ensure reliable starts in all weather conditions.

Reserve Capacity (RC)

Reserve capacity (RC) indicates how long a battery can power essential systems if the alternator fails. Choose a replacement battery with a comparable RC to maintain your vehicle’s performance during unexpected situations.

Brand and Quality

Opt for reputable brands known for producing high-quality batteries. Investing in a reliable battery ensures longevity and consistent performance. Brands such as Optima, DieHard, and Interstate offer excellent options for H6 battery replacements.
