When it comes to off-road driving and expeditions, you can't compromise, especially when you’re on the moon or the middle of a national forest. When you're far away from civilization, you need a battery that won't fail you, you need an Optima Battery.

Optima Batteries feature Optima's proprietary Spiracell Technology, a science that was originally designed the first moon buggy. This is why even outer-space off-roaders demand Spiracell-based batteries: 

Traditional batteries consist of lead plates surrounded by acid, but Optima batteries consist of two thin lead plates wound into a tight spiral cell, with an absorbent glass-mat in between to hold the electrolyte solution. This provides more surface area and evenly distributes pressure over the entire lead surface allowing for three times the normal lifespan than conventional batteries. These batteries can also sit for three times the time of a conventional battery without charging.

An additional factor behind the extended lifespan of an Optima battery is the design’s heat resistance. Optima battery is not shortened by overheating. When a conventional battery heats up under extreme off-road conditions, the resulting acid density seriously decreases battery life.

The larger lead surface area also allows for quicker recharging than conventional batteries.

The outer construction of Optima batteries is completely sealed. You never need to add water and because there are no flowing electrolytes, no corrosion can form on the posts. This system is completely welded together and will not alter power output during rough roads, collisions, or sudden temperature changes. Optima batteries are 15 times more resistant to vibration than other batteries.
