Optima D51 YellowTop battery brings forth advanced performance and deep-cycling capability that your vehicle demands if it has a lot of electronic equipment like lights, high-performance stereo/AV system, winches, or hydraulics.

This amazing Group 51 battery features Spiral- wound cells technology comprising two pure Lead plates coated in a precise coating of lead oxide. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance. Extreme temperature tolerances, humidity, and automated processes are maintained and constantly monitored.

Equipped with a decent cold-cranking amp and deep cycle, Optima OPT8071-167 D51 requires very low maintenance of changing water and electrolyte monitoring offering x3 longer life as compared to other Group 51 batteries. Moreover, you can mount this battery virtually in any position without any fear of acid spill and leakage. Mechanical stress and vibration are tolerated about 15 times more than the traditional resistance of other batteries.

The Optima battery is ideal for seasonal use because of its very low self-discharge rate with 300 charges/discharge cycles. 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.
