- Faster recharging
- Optimal starting power
Designed to replace a conventional LSI (Light, Starting, Ignition) battery used in cars and trucks. Like all Optima batteries, the Absorbed-Glass-Mat Optima Spiralcell Technology uses pure, unalloyed lead electrodes for lower internal resistance, less outgassing and water consumption, better surface-to-weight ratio and improved vibration resistance. Pound for pound Optima performance is unmatched. You’ll never need to add water to an Optima battery, because it recombines hydrogen and oxygen inside the battery instead of venting them. The sulfuric acid electrolyte is absorbed into a fiberglass mat between the electrodes, so it can’t spill, even if the battery is mounted on its side, or cracks open.
Optima Batteries has been a subsidiary of Johnson Controls since 2000, although the patents for Optima’s style of AGM spiral-cell batteries have been around since the 1970’s. Johnson Controls is a major, world-class player in the vehicle battery, commercial HVAC, automotive seat, interior and electronics field. Optima Batteries are always manufactured in Optima-owned facilities to their demanding standards, and never relabeled or resold. Optima® offers ultimate professionals and enthusiasts all the power they can handle again and again.
