Operator Controls

The gang charger does not have operator controls or a power switch. There is no dedicated indicator light
to show that the charger is powered, but the charge slot LEDs will light.
6.7.4

Charge Indicators

Each battery charge slot is equipped with four LEDs to indicate the charge status of the battery. When the
EP10 batteries are inserted in the charger, the colour and behaviour of the LEDs associated with the charge
wells in use indicate the status of the charge.

Charging Batteries

• Slide an EP10 battery, as shown, into each charge compartment until the battery touches the base of
the charge compartment. Ensure that the contacts on the battery meet the contacts in the battery
charge bay.
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 0° C and 40° C (32° F to 104° F), the LED flashes yellow until the tempera-
ture is acceptable. A fully discharged battery will normally 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 17.

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.
• Reconnect the mains power cable, and check that the slot indicator flashes at power up.
