Product Description

Optima D31A 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.

My battery arrived in a reasonable amount of time, well packaged, and in good condition. It has worked well for me. I'd recommend it to anyone.

i've been using the d31 blue top for a long time now and noticed the price on the yellow top dropped. Optima says the blue is for deep cycle trolling motor use while yellow is for deep cycle and starting use - however I have it on good authority from optima that the d31m marine battery is the same inside both the blue and yellow tops, so if the yellow is cheaper today, I'll buy it instead!
