Interstate's AGM batteries, No. MT7, meet the demand for power and cranking by integrating glassmat technology in group sizes 34, 65 and 78. The battery can meet the cranking and reserve power demands of highly accessorized late-model vehicles that power cellphones, backup sensors, GPS navigators and more. Internally the combination of pure lead without the common impurities of alloyed lead and increased surface area of the thinner plates results in a battery that performs at an extremely high level in both cranking the engine and powering electrical accessories over and over again.
