One S1
Battery Test
Tools Required
• Multimeter
Removal
1. Remove both battery covers (page14).
2. Remove both batteries (page15).
WARNING!
Do not touch any internal electrical components
until after you have removed BOTH batteries and
pressed the ON/OFF button to discharge the
residual power. Failure to do so could result in
serious bodily injury from electric shock.
3. Press the ON/OFF button until all lights are off to
discharge any power remaining in the One S1.
4. Set the multimeter to measure DC voltage.
5. Measure the battery voltage. Probe the battery’s
yellow connector, as shown in Figure 7.
6. The voltage should be 50–62 VDC. If it is higher
or lower there is a problem with the battery.
Contact Segway (page3) for a replacement
battery.
CAUTION!
When measuring battery voltage with a
multimeter, be careful not to short the test
probes or the two pins in the battery connector.
Doing so could result in a hazardous release of
stored energy.
Installation
1. Install the battery (page15).
