NOTE - Because batteries charge and discharge
slowly, diagnosing battery problems in the field can
be difficult. As batteries age their capacity drops
and the ability to store energy is lost. Despite this,
faulty batteries can still draw charge current and
develop voltage. A worn out battery can sometimes
appear good. A proper method for testing a battery
consists of bringing the battery to the fullest state of
charge possible, and then discharging the battery
and measuring the energy delivered. While time
consuming, this method can be employed in the
field. If the battery can supply the load for the
desired time; it can be deemed good. If the battery
will not accept charge or cannot deliver the required
energy; it is worn out. In many circumstances it may
be more economical to replace a suspect battery
rather than perform a full charge-discharge test.
