Power to spare

Smaller than the 65 series it replaced but not short on cranking amps. Base plate adapters made it a breeze to replace. Priced a bit higher than a service station replacement but in my opinion worth the extra. Maintenance free and looks great in the engine bay.

great battery

Works like a charm with my explorer. The only problem I had is connecting plus terminal since explorer has a particular shape for it, and it didn't quite fit at first, but I somehow manage after little "persuasion".

I am very pleased with my OPTIMA Red top battery. After researching many different on line and local sources I ordered from auto because of best price, service and delivery.

Optima Red Top Batteries

So far, so good. Purchased two for my Ram 2500 pickup with a 5.9 Cummins diesel. Truck has been starting every time with no degredation in battery performance or power. Have a low current drain that I have not been able to isolate and which impacted battery life with the Die Hards I previously had installed,so I put in two quick release isolators that are providing a temporary solution to the drain problem. Batteries remain fully charged between starts.

Great Batteries that work well in the cold weather

I love the batteries I purchased and I saved a ton with the price match from I have these batteries in my 2003 Ram 3500 5.9L diesel and the beast starts everytime without the aid of a block heater. I have only tested the batteries at 12 degrees F. I am sure they will work when it reaches -25 degrees F.

Shiping was fast,I have a 2004 jeep with a 4.0 . The red top battery made a big difference on the way the engine turns over on cold winter days.
