How much does a battery power cable cost

Some battery cable replacement cost estimates using common vehicles and $100 an hour labor rate are presented below: Please take note though that these are all for factory battery cables. There aren't generally good aftermarket sources for pre-made battery cables. However, a few older vehicles can use universal. Battery cables are usually replaced when they corrode at their battery terminal point, and sometimes corrosion can continue into the cable insulation. That causes resistance and poor. If the cause for replacement is corrosion at the battery terminal, then, one alternative is to replace just the terminal as long as enough clean cable remains. In many cases, the positive terminal bolts on to the cable end and can be replaced without the cable. On the negative.
