What happens if I put a lower CCA battery in my car?

If your battery has a CCA rating which is too low, the motor won't receive the current it needs during the start up process. This can cause heat and additional stress on the parts of the motor as the electric motor will be starved of current.

Does charging a battery increase CCA?

The time required to recharge a battery is a function of its CCA because the same amount of energy must be put back into the cells as was depleted. Therefore, the greater the amount of current (amps) a charger produces, the shorter the time it will take to fully charge the battery.
