In traditional flooded batteries, the positive and negative grids hang inside a box submerged in an acid solution.  With AGM batteries, positive and negative plates are separated by an absorbent glass mat that holds the electrolyte like a sponge. This minimizes the potential for electrolyte spillage. 

OPTIMA^® AGM batteries also use a higher purity of lead than many other AGM and typical flooded cell batteries at 99.99% pure, virgin lead. This higher purity means fewer contaminants and a lower incidence of gassing, which extends battery life and increases performance.

The OPTIMA battery’s design advantages include lower internal resistance and greater plate area for superior starting power, the ability to recharge much faster, and higher voltage characteristics during discharge. And it’s virtually spillproof, whether it’s cracked or damaged. Also, OPTIMA AGM batteries withstand vibration like a champ.

OPTIMA batteries high performance AGM battery benefits:

• Impressively high cranking characteristics in a small battery
• Higher charge acceptance during recharges
• Sealed maintenance-free design
• Virtually spillproof
• Shock and vibration resistant
• More power per pound as compared to standard batteries
• Long service life
