Product Description

Optima D51R YellowTop battery provides the extra performance and deep-cycling capability that your vehicle demands if it has a lot of accessories like running lights, high-performance stereo/AV system, winches, or hydraulics. The unique SpiralCell design provides a strong and clean power source, ensuring the safety of you, your family and the environment. The Optima battery is ideal for seasonal use because of its very low self-discharge rate. That means you can store your seasonal vehicles all winter without regular charging and still spring out of the starting block when winter is over.

Customer Reviews

Only a 30-day warranty
My D51R went bad after a month. Optima says take it back to whom you purchased it from. I said Amazon, they said "oh no." Optima will not honor the 36 Month Warranty and Amazon said I'm stuck because I can't ship it back -it's hazardous material and it's beyond the 30 day return policy. "We are real sorry, but there's nothing we can do." So if you are going to buy a battery from Amazon - you will be stuck - without any remedy. Join the suckers club with me.

Works for the First-Gen Miata
Installed this battery ("R" means reverse polarity) in my 1992 Miata this morning and it fit well. It's maybe an inch taller than the Westco battery or OEM Panasonic battery, so I had to extend the threaded rod that holds the top bracket, but otherwise it went in easily and the polarity was correct. The car fired right up, so I'm happy so far. I'll post again if I have any problems.

Great....but not quite perfect
The description of this battery stated that it was made to fit Honda Civics specifically, which is the application that I wanted it for. The only problem is that the top is contoured in such a way that the top mounting bracket does not fit properly and a shim must be made so that the clamp will clamp and not slide back and forth and side to side.

I chose this battery over the Odyssey which had better cca for pole orientation. Optima kept the terminals on top so that my stock connectors could be used, with the Odyssey they would have to be modified.
