The 31-AGM7, the new extreme absorbed glass-mat battery from Interstate Batteries, features deep-cycling performance, faster recharging and stronger starting, according to the company.


Batteries run through several cycles of discharging and recharging power. Most starting batteries don't typically discharge deeper than a 10% depth of discharge, the company says. Interstate's AGM battery with Pure Matrix Power, on the other hand, produces 400 cycles at 80% depth of discharge.

Pure Matrix Power is a combination of pure non-alloy lead and an extra thin plate design. The pure lead without the common impurities of alloyed lead and the increased surface area of the thinner plates results in a battery that peforms at an extremely high level in both cranking the engine and powering electrical accessories over and over again.

"Interstate Batteries' new AGM battery can accept and produce a tremendous amount of current very quickly, reducing the battery's charge time," says Gale Kimbrough, Interstate Batteries' technical services manager. "Additionally, extreme cold and extreme heat challenge a battery's ability to perform, and this new AGM battery, with its temperature-resistant properties, rises to this challenge by delivering at a high level in all climates."

Thick glass-mats inside the AGM battery absorb the battery's active ingredient. Electrolyte, a mixture of sulfuric acid and water, is housed in a liquid state in most automotive batteries.

The Interstate Batteries 31-AGM7 battery works well for both starting engines and non-cranking applications, such as the many auxiliary power applications on a commercial vehicle. These include auxiliary power units, heating, ventilation and air conditioning, power generators, lift gates, solar panels and other heavy-cycling applications.
