The numbers on a battery typically indicate its size, capacity, and specifications. For example, in a car battery, the numbers might refer to the group size, cold cranking amps (CCA), and reserve capacity (RC). In smaller batteries, like AA or AAA, the numbers can indicate voltage and milliampere-hours (mAh), which measure the energy storage capacity.
