303 Battery Capacity Test

IMPORTANT:
The battery capacity test discharges the batteries to the "Low DC warning" and displays estimated
runtime. This estimate is only correct for the unit's condition at the time of the battery capacity test.
If the load changes and you would like to display estimated runtime, you must perform this test
again. After a battery capacity test, the unit must charge the batteries for at least eight hours
before it has full battery capacity and full runtime.
