Battery terminal connectors play a vital role in engine starting and distributing power throughout the vehicle or equipment. Overtime corrosion, dirt and debris can accumulate on and around the battery terminal and battery post causing the the terminal to erode. This will cause failure to start and could harm other on-board electronics. Battery terminals should be inspected during routine maintenance, cleaned and replaced if needed. These can be used in any application from automotive all the way up to the heaviest of equipment.
