Rock Racing Battery

Rock Battery 16 Volt Ultralight Battery The Ultimate Racing Battery Has Arrived at Rock Racing Battery !!

The 9 pound ultra light weight, which is approximately 35 pounds lighter than other light weight racing batteries, to its Incredibly Flat Energy Discharge Curve,faster cranking speed, ultra hot ignition spark and higher sustained voltage our Lithium Power Source has become the benchmark for all Racing Batteries!

Whether Drag or Circle Track Racing with our Battery you will be making the same horsepower from the green, to victory circle.Racing with a hotter, more consistent ignition spark and no fear of detonation. The Rock Battery Ultralight Lithium Battery is also internally balanced. This ensures that the battery discharges and charges its prismatic cells equally. Cell balancing on the battery increases the durability and lifespan of the product dramatically. It is also an expensive option when building lithium batteries and that is why some (most) companies don’t do it.

With a Rock Battery You Get:

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.
