Paccar Parts' TRP Aftermarket Parts has full line of dependable batteries for truck, marine, school bus, transit bus and other commercial applications, offered in standard lead-acid designs, as well as newer Absorbed Glass Matt (AGM) technology. AGM are designed to provide better protection from the damaging effects of vibration than a traditional lead-acid battery. The TRP starting battery line-up offers batteries with up to 1,150 cold cranking amps (CCA) for reliable performance under the most adverse weather conditions; or as low as 650 CCAs for warmer climates, where longevity is needed more than cranking power. The TRP dual-purpose batteries allow for more frequent discharge and recharge of the battery with their heavier, thicker plates. Fiberglass strands imbedded into the plate surfaces lock active material to the plates, preventing shorts between the plates.
