Step 2: Set Full Charge Voltage
Set the Full Charge Voltage parameter by taking the following steps:
1. Plug in the charger.
2. Fully charge the batteries.
3. With the charger still attached and running, measure the battery voltage with a voltmeter.
4. Set Full Charge Voltage to 0.02V lower than the measured voltage divided by the battery’s number
of cells.
Step 3: Set Reset Volts Per Cell
Set the Reset Volts Per Cell parameter by taking the following steps:
1. Turn o or disconnect the charger.
2. Let the batteries sit for 1 hour.
3. Measure the battery voltage with a voltmeter.
4. Set Reset Volts Per Cell to 0.02V lower than the measured voltage divided by the battery’s number
of cells.
Step 4: Set Full Volts Per Cell
Set the Full Volts Per Cell parameter by taking the following steps.
1. Select a medium speed mode and drive the vehicle on a level surface for 10–15 minutes.
2. Select Monitor » Battery.
3. Note the voltage displayed in the Keyswitch Voltage eld.
4. Set the Full Volts Per Cell parameter to the observed voltage divided by the battery’s number of
cells.
Step 5: Set Empty Volts Per Cell
e 1.73V value to which you previously set the Empty Volts Per Cell parameter should work for
most batteries. However, you may need increase the Empty Volts Per Cell value for some sealed
