Advanced Troubleshooting Guide
How do I know if the battery needs to be replaced?
Indications that it might need replacement:
• Does not hold a charge
• Slower lift speed
• Grinding noise
• Unit won’t lift at all
• Shorter time in between charging
• Battery is leaking
Diagnostic Instructions:
1. Check the charger with a multi-meter set to Volts DC. Place the positive lead in the center of the
adapter and touch the negative lead to the outside (Figure 1). Voltage should read 15V or higher
when plugged into an AC outlet.
2. Remove the battery cover and remove wires from the terminals; measure the voltage across the
wires when the charger is plugged into the LiftPlus and the AC outlet (Figure 2). Should read
approximately 15V. This means power is getting from the control board to the wire terminals.
NOTE: This voltage may have slightly lower readings because the controller will limit charge
getting to battery in relation to how much “charge” is in the battery - the higher the battery
charge, the lower the voltage going in. This permits you to leave the charger plugged into the
LiftPlus as often as you’d like without overcharging it.
3. With the terminal wires still removed from the battery, measure the voltage across the battery
terminals (Figure 3). Ideally the battery should read 12 to 12.6V.
4. If the voltage is lower than 12V:
• Charge overnight.
• After charging, check voltage across battery terminals:
• Under 12V - replace battery
• 12 to 12.6V - Normal
• Place a load on the LiftPlus and run up and down a few cycles. If voltage drops from 12V, you
should replace the battery.
