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.
Sealed Lead Acid Battery

All the reviews that say their battery failed, and Amazon would not honor the warranty, are dead wrong. Amazon sent me a replacement battery at no charge, and told me to keep my old battery and dispose of it. If you try and do the return via the website it will not allow you, because they will not accept the return of the old battery for safety concerns, but if you talk to the Large Items Customer Service center, they will honor it without a hesitation. All these people complaining simply did not make a five minute phone call.
As for the quality of the battery, I have 3 other Optima's that have been incredibly reliable. My oldest is over four years, this one being my fourth, and the only one to fail after about 13 months. I consider them to be the best AGM battery for the price at only $30-$50 more than an OE flooded lead battery which typically only have a 1-2 year warranty compared to Optima's 3 year.
And to beat a dead horse a little more, the Amazon...
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.
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.
