Figure 15: Interpreting the Battery Status Meter
6.4 Battery Use
The CRA-B27 battery has a Lithium-ion cell with advanced features to allow effective use and
management of its life. Usually, a new battery is only charged partially and should be fully charged before
initial use. The battery has a built-in power gauge status indicator that turns on when the power gauge
button on the battery is pressed, when the trigger is pulled or when one of the scan buttons is pressed.
When a battery is being charged either in a reader or in a quad-bay battery charger, the battery LEDs will
flash. As power level increases, more LEDs will flash. Once it is fully charged, four LEDs will stay on solid.
The CRA-B27 battery has a built-in health check that tracks residual power capacity against a new
cell. See section 13.3 for the M-Code to output battery health information as a percentage of a new
cell. Depending on use intensity and workflow, replace the battery when the residual capacity drops
below a predetermined level to ensure that the battery will always last through a full shift. Code
recommends replacing the battery when residual capacity drops below 80%, which equates about 500
charging cycles.
