While this battery can deliver plenty of starting power, it is specifically designed to withstand the special rigors of long, deep discharges and long, slow recharges. These super deep discharges and recharges can literally tear ordinary batteries apart from the inside. Sitting in a discharged condition causes the battery to corrode on the inside, just like iron rusts and corrodes in the salt air. If not recharged promptly and properly, the plates in a battery can disintegrate and fall apart in short order. This battery is specifically designed to withstand this harsh environment.
