Checking Battery Charge Level - Invacare TDX SP2 Service Manual

Invacare® TDX® SP2 Series
7. Carefully push the remote forward, trying to drive the
mobility device through the stationary object. The load
should draw between 30 to 40 amps from the batteries
for 0.3 seconds.
Performing this 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 mobility device.
8. Read the meter while the motors are straining to
determine the voltage under load.
If the voltage drops more than 2 volts from a
pair of fully charged batteries during the 0.3
seconds, they should be replaced regardless of
the unloaded voltages.
