7978 Gang Charger
8.5 7978 Gang Charger
The 7978 Gang charger can charge up to three Lithium-Ion batteries at one time.
8.5.1 Connecting The Power Source
The 7978 Gang Charger is powered with an external universal AC power supply. It
accepts voltages ranging from 100-240 volts AC, 50/60 Hz. The power supply has
an IEC 20 type connector for the AC input and a DC output cord with attached plug.
• Plug the female end of the AC line cord into the IEC 320 type connector on
the external power supply.
• Plug the power supply DC output cord with attached plug into the charger.
• Plug the other end of the AC line cord into an appropriate power source.
All front panel LEDs turn on momentarily. The ‘Power On’ LED then remains on
indicating a power connection.
8.5.2 Inserting And Charging The Battery
The 7978 Gang Charger has a “Power On” LED and each charge pocket has three
LEDs – Charge, Fault and Ready. Ensure that the green “Power On” LED at the
front left side of the charger is “on”. The battery charge pockets are moulded,
making it easy to snap the batteries into the pockets.
• With the four electrical contacts facing down and textured plastic battery
surface facing the front of the charger, insert the battery into a charger
pocket. It should click into place.
Charging will begin immediately.
Battery Charged And Ready
When the amber “Charge” LED turns off and the green “Ready” LED turns on, the
fast charge cycle is complete, and the battery is ready for use.
Typically, a fast charge takes 3.5 to 4 hours. Note that for Lithium-Ion batteries,
70% of the charge occurs within the first hour.
