Charging Batteries

• Install the battery with the battery contacts facing the charger. Slide the battery between
the guide rails until it lightly latches in place.
The 4-LED bar for the battery bay shows 25% charger per LED. A flashing green LED
shows charging is under way. The LED directly below the slot in which a battery is inserted
lights up immediately. If the battery temperature is outside 5°C to 39°C (41°F to 102°F), the
LED flashes yellow until the temperature is acceptable. A fully discharged battery will nor-
mally take from 3 to 4 hours to charge. At full capacity, it turns solid green.
When the battery is fully charged, the charger stops applying power; the battery cannot be
overcharged if left in the charger slot.

Troubleshooting

6.7.6.1 Improper Battery Storage

Storing batteries in the gang charger for extended periods (more than a week or two) is not
recommended. Lithium-ion batteries lose capacity if they are maintained at full charge for
long periods of time. See the battery handling recommendations in "The Battery" on
page 12.

6.7.6.2 Power LED Does Not Light Up

• Remove all batteries, and unplug the charger.
• Connect another device to the mains outlet to ensure there is power.
• Remove the IEC mains power cable from the charger, and check it for damage.
• Reconnect the mains cable in the charger and mains outlet.

6.7.6.3 Indicator Does Not Light When Battery Installed

• Remove the battery, and clean the contacts on the battery and the charge slot.
• Reinstall the battery, and check that it is fully seated in the slot.
• Inspect the charge slot contacts for damage (are they bent, flattened, twisted or broken).
• Try inserting a battery that you know to be working in the charger slot.
