Replacing Batteries; Replacing Batteries In Pairs - Segway PT x2 Reference Manual

Replacing Batteries

Your Segway PT is powered by two rechargeable Li-ion Batteries.
With normal usage and proper maintenance, Batteries should last the
equivalent of 600 to 1000 full charges. As your Batteries near the end
of their useful life, they need more frequent charging and your
Segway PT's range will be reduced. To order replacement Batteries,
contact an Authorized Segway Dealer or Distributor.

Replacing Batteries in Pairs

Whenever you need to replace a Battery, consider replacing both
Batteries, and always use pairs of Batteries with the same chem-
istry. Replacing only one Battery will not necessarily increase the
performance or range of your Segway PT, because the Segway
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 Bat-
tery is replaced because of damage or defect and the other Bat-
tery is relatively new).
For information on removing and reseating
Batteries, see "Removing the Batteries" on page
100 and "Reattaching the Batteries" on page 102.
