Schumacher XCS15, XC12 owner manual Calculating charge time, Model XC6, Model XC10

Power-Up Idle Time Limit: If no button is pressed within 10 minutes after the battery charger is first powered up, the charger will automatically switch from tester to charger if a battery is connected. In that case, the charger will be set to charge at the maintain mode and gel cell battery type.

Testing After Charging: After the unit has been changed from tester to charger (by selecting a charge rate), it remains a charger. To change the battery charger back to a tester, press the CHARGE RATE button until all charge rate LEDs are off.
