La Crosse Technology BC-900 Trickle Charging, Display Mode Information, Current Time Capacity

TRICKLE CHARGING

After the rechargeable battery is fully charged in any of the operating modes, the charger will give a small amount of current to the rechargeable batteries to maintain the fully charged level. This mode is automatically launched after rechargeable batteries are fully charged and kept in the charging unit. The signal “Full” will be displayed on the LCD.

DISPLAY MODE INFORMATION

The user can use different display modes to monitor the rechargeable battery condition during the different operations (see below figure and Table 4 to 7).

Different display modes are exhibited: Charging current, Time, Voltage and Capacity
