Batteries for Cars and Light Commercial Vehicles

Starting Power - The Cold Cranking Performance or CCA measures the starting power of the battery. This means that the higher the CCA value, the easier it is to start the vehicle.

The Ampere Hour Capacity or Ah measures the total amount of charge stored in the battery. An Ampere Hour represents the amount of electricity when a current of 1 Ampere passes for 1 hour.

The Ampere Hour Capacity varies with the rate at which the battery is discharged; the slower the discharge, the larger the amount of electricity that the battery will deliver.

The Ampere Hour Capacity is the amount of electricity that a battery will deliver during 20 hours before the voltage falls to 10.50V. e.g. a 60Ah battery will deliver a current of 3A for 20 hours.
