Click. That's one of the worst sounds you can hear after turning an ignition key. It's worse yet when that telltale click—the sign of a dead or discharged battery—could have been prevented by a better battery.
What's a better battery? It's a battery that just plain works. It's a battery that lasts a long time, reliably starts your engine no matter what the weather, and won't leak under any circumstance.
Interstate has a new battery to offer, and it's got all the qualities of the better battery mentioned above. The new Interstate battery is called the MT7. It's available in battery group sizes 34, 65, and 78. The technology that gives the MT7 all the “better battery” qualities is called AGM, or absorbed glass mat.
An AGM battery is made by using a fiberglass mat sandwiched between the negative and positive plates inside the battery case. The fiberglass mat absorbs 99.9 percent of the electrolyte. Instead of cells that are flooded with a liquid electrolyte, an AGM battery has this fiberglass material that is filled with the electrolyte. With lead plates and electrolyte-saturated fiberglass mat filling the interior of the battery case, the AGM battery acts as a single solid unit. The lead plates are the latest technology and the elctrolyte won't leak out.
There's more. You can safely mount an AGM battery inside the vehicle, and you can mount it in any position except upside down.
The lead plates of the MT7 are unique. They're ultra-thin and are made of 99.9 percent pure, non-alloyed lead. Interstate calls this plate technology Pure Matrix Power.
The AGM-style Interstate MT7 battery is perfect for off-road applications because it's vibration-resistant and can reliably power winches and off-road lights. It can be deeply discharged many, many times without damage and will also recharge quickly. You'll only have to think about the MT7 when you're installing it. Once in place, the MT7 goes to work, maintenance-free. It's pure power for your truck's electrical system.
