Optima Red Top
At my work we used to use Optima Red Tops exclusively, and would go through hundreds per year on our diesel pumps. That lasted until late last year when we received a shipment of over 50 batteries that were all unable to hold a charge. We also had several that failed within two months of being sold that were part of a different shipment. Needless to say we have stopped using Optima batteries. We were told that the quality dropped quite a bit once they outsourced production.
That said, I have no idea what battery I'll buy when my OEM finally dies. Probably a Duralast from AutoZone.
you cant use a regular charger to recharge them either. you have to "slow charge" them or something...
The best thing about red tops are the warranty where they keep replacing them
