At DCPower, we only deal in quality products. Everything we sell must pass our own in-house testing, to ensure that we are satisfied you’re buying a product that will go the distance.

What is CCA?

CCA stands for Cold Cranking Amps. This is a measure the starting performance of a battery. The rating is based on the number of amps that a battery can supply for 30 seconds at -18ºC while maintaining a voltage of 1.2V per cell.  The higher the rating, the greater the starting capacity of the battery.

What is RC?

RC stands for Reserve Capacity. This rating determines how many minutes a fully charged battery can deliver a constant current of 25 amps at 27ºC without falling below a voltage of 1.75 volts per cell.

What is the difference between a Starting battery and a Deep Cycle battery?

A Starting battery is designed to provide a high spike of current, for a short period of time – such as is required to start an engine. In this situation, the small amount of energy taken from the battery is immediately replaced by the alternator.

A Deep Cycle battery is designed to provide a constant current over a long period of time. Deep Cycle batteries can be discharged and recharged over and over again without causing damage to the battery.

What is a calcium battery?

Calcium is an additive to the electrolyte, which increases the cranking capacity of a battery and allows it to be ‘maintenance free’. Most automotive batteries on the market these days have some form of calcium additive.
