Deeply Discharged Batteries
Deep discharge occurs when a battery is discharged to less than 3.0
volts. The battery chargers have a Recovery mode designed to restore
charge to a deeply discharged battery.
When the charger detects a deeply discharged battery, it automatically
enters Recovery mode which supplies reduced current to the battery
for up to 30 minutes.
If recovery is successful, the charger will exit Recovery mode and
charge the battery to capacity. If the battery cannot be recharged,
charging stops and the battery must be replaced.
