You should have your battery and charging system checked . at least once a year b. no more than once a year c. at least twice a year d. no more than twice a year

The correct answer is A) At least once a year

Explanation:

The battery and charging systems are very robust. However, they play such an important part that it is better to maintain and upkeep for maximum performance.

Once a year is an ideal time to check the charging and battery. If you have the time and expertise, you can obviously do it twice a year.

If you only do it once a year, it is better to do in the Fall, before winter arrives, so you are prepared.
