ANSWER: The most common battery rating is the AMP-HOUR RATING. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.)

There is no simple calculation method involved. Basically the equation is Labor + Parts + Type of bumper = Cost. Shop prices range from $30 an hour for labor up to $80 or more, so itâs impossible to offer a price. If you repair it yourself, you are simply looking at the cost of materials.
