- An AGM battery has a lower internal resistance than a flooded lead-acid battery, which allows faster recharge.
- The AGM battery doesn't produce nor expel hydrogen/oxygen gasses like the flooded lead-acid battery. Therefore, it doesn't have any electrolyte or water loss.
- When comparing the same group size battery, AGM batteries allow additional plate surface area. More plate surface area = high ratings in cold cranking amps (CCA) and/or reserve capacity (RC).
- AGM batteries do not exhibit terminal corrosion. No corrosion means less battery maintenance.
