Checking Battery Charge Level - Invacare ProntoM41 Service Manual

SERVICE MANUAL
●
Run the wheelchair in neutral for at least 2 minutes.
●
Sit in wheelchair and place your feet against a door jam, workbench, or other stationary object.
●
Carefully push the joystick forward, trying to drive the wheelchair through the stationary object.
The load should draw between 30 to 40 amps from the batteries for 0.3 seconds.
Note
Performing the last step puts a heavy load on the batteries as they try to push through the
stationary object. If the wheels spin, have two individuals (one on each arm) apply as much
downward pressure as possible on the arms of the wheelchair.
●
Read the meter while the motors are straining to determine the voltage under load.
Note
If the voltage drops more than 2.5 volts from a pair of fully charged batteries during the 0.3
seconds, they should be replaced regardless of the unloaded voltages.
