Segway Personal Transporter SE Service Manual 3–2
Batteries
When replacing a Battery, consider replacing both Batteries,
and always use pairs of Batteries with the same chemistry.
Replacing only one Battery will not necessarily increase the
performance or range of the PT, because the PT is designed to
operate only at the level allowed by the lower-energy Battery.
Redundancy is a critical safety feature built into the Segway
PT that also applies to the Batteries. Therefore, you should
replace Batteries in pairs (except for the unusual situation
where a Battery is replaced because of damage or defect and
the other Battery is relatively new).
NOTICE
To isolate a problem in a specific battery, swap front and
rear Batteries to confirm that the error condition follows the
Battery.
Removal
Tool Required: 3 mm hex wrench
1. Make sure the PT is powered off and unplugged.
2. Tip the PT onto its side so the Wheel lies flat against
a smooth, clean surface.
3. Using a 3 mm hex wrench, remove the battery
fasteners (4 per battery). See Figure 3–1
4. Pull the Battery straight off the chassis.
5. Repeat steps 3 and 4 for the other Battery.
NOTICE
Consult your local recycling center for proper disposal of
Batteries.
