We have all heard of the term “
dead battery”, or experienced this issue ourselves. But it is important to note that a “dead battery” does not necessarily mean the battery is at fault. vehicle's exhibiting the symptoms noted above will be connected to a starting and charging system test machine. This is an advanced device that will test every part of the starting and charging system automatically by following onscreen instructions. The machine will display results, and indicate the possibility of battery failure, but may also require the servicing technician to complete visual inspections while testing is in progress. If the battery is found to be discharged below the required voltage, it will be recharged, retested, and possibly replaced. It is also possible to use the service of a battery tester at many auto parts suppliers. This requires the battery to be removed, connected to a charger, and tested under a set of load ranges after the battery is charged. If the battery fails at these load ranges or fails to charge, it will be considered faulty.
