Champion batteries are definitely not the best batteries out there. They will last from 2-3 years and you will be replacing them again.

DRiV warrants qualifying Champion ® products against defects and wear-out when used on private passenger cars and light trucks under normal operating conditions, for as long as such original purchaser owns the vehicle on which they were originally installed.

What are the advantages of the AGM battery? AGM batteries have a very low internal resistance, are capable to deliver high currents on demand and offer relative long service life, even when deep-cycled. AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead-acid type.

AGM Batteries Like other lead-acid batteries, the depth of discharge is about 80% when new and 50% when older. This makes them less competitive compared to lithium-ion batteries. Winner: Lithium-ion batteries have the highest depth of discharge and a longer operating time.
