Lower internal resistance for repeated engine starts.
Better shock and vibration resistance than standard wet cell (flooded) or gelled electrolyte battery designs.
Twice as many discharge/charge cycles as the leading gel cell battery depending on the depth of the discharges.
Faster recharging. No current limitations with voltage regulated recharging (14.4 volts). Much better charge retention than lower cost wet cell batteries, even at high ambient temperatures.
Less than 3% self discharge per month at 77˚ Fahrenheit.
Even less at lower temperatures.
Sealed construction with absorbed electrolyte means that Rock Batteries are:
Submersible without damage
Can be installed in any position
Have no need for water
Not subject to shipping restrictions
Safety. Even during severe overcharge Rock Batteries produce less than 2% hydrogen gas.
A rugged, non-marring polypropylene case.
All Rock Batteries feature absorbed glass mat (AGM) battery technology. AGM technology was originally developed in 1985 for military aircraft usage where, just like in racing, the battery’s power, weight, safety, and reliability are paramount considerations.
Rock Batteries are valve regulated sealed lead acid style (VRSLAB) recombinant gas batteries. Their compact size and high current capability, coupled with a quick charging cycle, make Rock Batteries the number one choice among top racers and racing teams.
Now, this technology has been incorporated into the Rock line of maintenance-free deep cycle racing batteries. Rock Batteries are designed to provide the increased power necessary for today’s racing electronics and engine starting requirements.
