Reconditioning Batteries
Each battery contains a microchip that monitors battery usage and tracks how much
capacity is available. This function can become less accurate because of temperature
fluctuations, aging, self-discharge, repeated partial charging, and other factors. This
inaccuracy is displayed on the System Statistics—Battery screen as Fuel Gauge
Error.
To ensure the accuracy of the battery’s internal capacity tracking system,
occasionally you need to recalibrate the battery. Reconditioning—also known as
recalibrating—is done by fully charging the battery, fully discharging it, recharging
it again, and then verifying that the error has been corrected.
You can recondition a battery internally or with the external charger. The charger
makes the process simpler.
Determining if a Battery Needs Reconditioning
NOTE After reconditioning, if the battery is not fully charged or still shows more than a
10% Fuel Gauge Error reading, repeat the reconditioning procedure. If the second
reconditioning does not restore a full charge and give an error reading of 10% or
less, the battery needs replacement. This error will affect all of the displayed battery
charge indicators.
Internal Reconditioning
If you don’t have the external battery charger, you can use the test set to recondition

the battery is greater than 10%, the battery needs
to be reconditioned.
