I know some people love to shit on Optima but my yellow top is still kickin at 10 years old. Been run to the ground a couple of times over the years and the slow charger brings it right back.

Pros: still kickin at 10 years
Cons: run to the ground

I have have good luck bringing sulfated Optimas to my local Interstate Battery. They’ve brought several back from the dead for me and they went on to last a very long time.

Pros: last a very long time

The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.

Cons: low amp hour rating, decreased fuel efficiency

Optimas are garbage. Mine didn't survive a 3 month work assignment. The battery was less than 2 years old, and fully charged when I left. Dead when I came back. Blew up like a football when I tried to charge it.

Cons: dead after 3 months
