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.)
2 â The Block. Round off an end of a block of wood to match the original shape of the inside of the bumper and place it against the dent. Tap it with the rubber mallet and check it every so often to see how the repair progresses.
Grand Total: All told, average bumper repairs run between $935 and $1,580. With the mechanical labor necessary to remove the bumper, the labor and materials needed to make it look like new, and the cost of the parts that make it all possible, itâs no surprise that car bumper repair costs have risen.
