Starting batteries are found mostly in automotive applications. However, they can also be found in some standby applications, especially backup starting power for fire pumps and generators. Sealed Performance Battery’s most popular starting batteries are in the Energizer Automotive and ACDelco range. The most common technology used is a calcium/calcium design, but with vehicles continuing to incorporate start/stop technology AGM and EFB batteries are becoming more popular due to their starting power and durability. The measurement used to calculate the starting power in these batteries are Cranking Amps (CA) and/or Cold Cranking Amps (CCA). This measurement indicates the starting power and is calculated by observing how much current can be discharged over 15 seconds at 0oC (CA) and -18oC (CCA). Generally speaking a battery with a higher CCA has more starting power.
Starting batteries that are more useful for commercial and industrial applications such as fire pumps and generators can be found in the Power Sonic and Zeal ranges. Their CCA can usually be found on the specification sheet or the battery itself.
