Charging time
To charge an empty battery pack:
Battery pack
B-SP2D-BT
• The charging time may differ depending on the condition of the battery pack or the temperature of the
environment.
NOTES:
1. Battery packs should be charged on condition that both ambient temperature and battery temperature fall within
a range of 0 ° C to 40 ° C.
2. The battery charger will get warmer during charging (room temperature + about 30°C). This is not abnormal
state.
3. When the CHARGE lamp blinks in red, it means a battery pack error. As the life of the battery pack may
be expired, replace it with a new one.
4. If the CHARGE lamp does not light in red even if a battery pack is installed, check the following:
• The AC power cord or AC adapter's plug may not be connected properly. Connect it properly.
• The charging terminal of the battery charger or the battery pack is stained. Wipe it clean with a dry soft cloth.
• When the battery's over discharge protector has been operated, leave the battery charger and the battery
pack alone for a few minutes. Stop using the battery pack if the CHARGE lamp does not light at all.
5. Periodically clean the charger terminals with a dry cloth.
