Understanding Battery Specifications

BCI GROUP SIZE

BCI Group Size describes the physical dimensions (LxWxH) and terminal configuration of the battery. Many vehicles can accommodate a battery from more than one group size. The BCI Group is not directly related to the performance of the battery.

Describes Physical Dimensions
COLD CRANKING AMPS (CCA)

Cold Cranking Amps (CCA) describe a battery's ability to start an engine in cold temperatures. This helps you understand how much power the battery is capable of delivering in short bursts. The higher the CCA rating, the greater the starting power of the battery.

Describes Performance
RESERVE CAPACITY (RC)

Reserve Capacity (RC) describes how long a charged battery can supply power without being recharged. This helps you understand how a battery can deliver energy over an extended period of time. More RC is beneficial for vehicles that aren't driven on a regular basis.

Attention California Customers - PROPOSITION 65 WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Batteries also contain other chemicals known to the State of California to cause cancer. WASH HANDS AFTER HANDLING.

It is illegal to dispose of a motor vehicle battery or other lead acid battery in a landfill. All car batteries can and should be recycled. Many towns have made hazardous waste drop-off free to encourage people to bring in materials rather than dumping them. In fact, some scrap yards will even pay you for your old automotive batteries! A quick internet search will help you find local drop off locations.
