Secton 11 - Battery Charger
ALL LED'S MUST BE OFF BEFORE
CONNECTING TO AC POWER
Charge Batteries
1. Plug the charger into a single phase AC socket with a nominal voltage rating of 100V, 110V,
115V, 120V, 220V, 230V, or 240V and a frequency rating of 50 or 60Hz.
• The charger automatically senses and adjusts to the AC voltage and frequency.
• At 110/120V the wall socket circuit breaker should be a 20A breaker with no other loads on
the circuit.
2. The charger will start automatically within a few seconds and begin charging the batteries.
3. The LED's indicate the charging progress.
• The yellow LED will turn ON and remain ON throughout the charging cycle.
• When the battery is 80% charged the green 80% LED will turn ON.
• When the battery is fully charged the green 100% LED will turn ON and the green 80% LED
will turn OFF.
• When the battery is fully charged the yellow LED will turn OFF indicating that the charger is
no longer charging.
• Charging time is dependent on depth of battery discharge, battery condition, and
temperature.
• If the charger is left plugged in after charging is complete (100% LED ON) the charger goes
into maintenance mode to keep batteries charged while in storage.
• The charger continuously measures battery voltage and restarts the charging cycle if the
battery voltage drops below about 50V. This keeps batteries charged while in storage but
does not boil-out the electrolyte over time.
4. Red FAULT LED
• ON: Battery pack probably bad, weak, or a bad cell.
• 1 FLASH: Open or short circuit. Remove from service until problem is identified and
corrected.
• 2 FLASH: Charger timed out. Battery pack probably bad, weak, or a bad cell. Unplug for 30
seconds, then plug in to start a new charge cycle.
Note: New batteries sometimes need 20 to 30 charge/discharge cycles before they charge normally.
The charger LEDs may only show yellow or 80% LED ON after overnight charging. Within a
few weeks the 100% LED will turn ON at the end of the charge cycle.
5. Turn OFF charger by unplugging (disconnect from AC voltage).
