9020-164 OPTIMA REDTOP Group 35 Battery

Whether you call them part numbers, SKUs, model numbers or something else, the numbers can get all jumbled when it comes to battery sizes. The 9020-164 SKU is for a boxed (it comes in a cardboard box) Group 35 OPTIMA REDTOP battery, that we sell factory-direct every day on our website. If the part number was 8020-164, it might be the same Group 35 OPTIMA REDTOP battery, except it doesn't come in a cardboard box. That might be a battery you would buy at one of our brick & mortar retail partner locations.

Did you know the key to maximizing car battery performance and lifespan is proper voltage maintenance? Fully-charged, REDTOP batteries, including the 9020-164 (we call it a group 35), will measure about 12.6-12.8 volts. We're so confident proper voltage maintenance will improve performance and extend lifespan, we'll increase the free replacement warranty on your OPTIMA battery, if you buy it and a Digital 1200 battery charger from us at the same time.
