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 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 chemistry.
Replacing only one Battery will not necessarily increase the performance or range of your 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 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).
For information on removing and attaching Batteries, see "Remove the Batteries" (p. 106) and "Install the Batteries" (p. 22).
