How are Battery Terminal End issues diagnosed?
When diagnosing a vehicle that suffers from a loss of battery power, the terminals will be visibly inspected, cleaned if necessary, and the battery will be charged. If the charged battery combined with the cleaned terminals will not provide sufficient electrical power to the vehicle, a technician will conduct a starting and charging test. If the test results show a reduction in power between the battery and battery cables, the terminals, and likely the battery cables, will be replaced.
How are Battery Terminal Ends Replaced?
There are two types of replacement battery terminals. The original-type cables will have an integrated battery terminal either bonded or pressed to the battery cable, while most aftermarket battery terminals are designed to receive the end of the existing battery cable. If aftermarket battery terminals are used, the old terminal will be cut off, and the battery cable will be tightened or crimped into the replacement. However, if original type parts are used, the battery cables will be replaced by disconnecting both ends of each battery cable.
RepairPal Recommendations for Battery Cable Terminal End issues
It is recommended to replace the cable with the terminal, as terminals that allow the existing battery cable to fasten to the new terminal are less reliable, require more maintenance, and are typically not as sturdy as factory terminals. Also, if the corrosion is severe, the battery cable could offer too much resistance to the battery, causing a failure to start the engine when the battery is only slightly drained.
What to look out for when dealing with Battery Terminal issues
When cleaning corrosion from or replacing battery terminals, it is imperative that the battery be disconnected before attempting this repair. The risk of electrical shock is high, and the risk of vehicle damaging battery arching is highly possible when the battery is being serviced. Due to the acidic nature of battery corrosion, rubber gloves should be worn before contacting the powder-like corrosion on the battery. Never cut a live battery cable, even with rubber handled cutting tools. This may cause electric shock.
Can I replace the Battery Cable Terminal Ends myself?
Cleaning or replacing battery terminals, even when the battery cables must be replaced is a fairly easy task. It does require basic tools and a solvent, but these objects are typical household items. When the battery cable must be replaced, it is much easier to replace one at a time, so the locations and fasteners are not confused.
