At 140
°
F Battery Pack temperature (60
°
C), the Segway HT will perform a Safety Shutdown. This
temperature can potentially damage the Battery Packs. The Segway HT can be restarted and will
operate normally when the Battery Packs have cooled down.
Safety Guidelines
WARNING! Unplug and disconnect your Segway HT from AC power before removing or installing
Battery Packs. It is hazardous to work on any part of your Segway HT when it is plugged into AC
power. You risk serious bodily injury from electric shock as well as damage to your Segway HT.
The cells within the Battery Packs contain toxic
substances. Do not attempt to open Battery Packs.
Do not insert any object into the Battery Packs or use any device to pry at the Battery Pack casing. If
you insert an object into any of the Battery Packs’ ports or openings you could suffer electric shock,
injury, burns, or cause a fire. Attempting to open the Battery Pack casing will damage the casing and
could release toxic and harmful substances.
Use care when handling the Battery Packs. If you are transporting your Segway HT, be sure to
protect the Battery Packs to avoid damage during shipment. If the casing or gaskets of a Battery Pack
should break open, leak any substance, become excessively hot, or if you detect an unusual odor, do
not use the Battery Pack. Do not handle a damaged or leaking Battery Pack unless you are wearing
protective rubber gloves. Dispose of the rubber gloves and damaged Battery Pack properly in
accordance with regulations governing disposal of toxic materials.
Keep Battery Packs out of reach of children and pets. Ingesting toxic substances and exposure to
battery voltage could result in death or serious injury.
Charging
Heat is produced when charging NiMH Battery Packs. It is very important to the life and performance
of the Battery Packs that they remain in the appropriate temperature range during charging.
If you attempt to charge the Battery Packs, and the Battery Pack temperature is below 32
°
F (0
°
C) or
above 40
°
C (104
°
F), the Battery Packs will not “quick charge” (solid green LEDs/second stage of
charging). The charge supply will continue to blink, indicating a slow or trickle charge, until the
temperature stabilizes inside the range. This is to protect the Battery Packs from damage.
Even if you leave the Segway HT plugged in for an extended period of time (beyond six hours), and
return to see the LEDs blinking, the Battery Packs may have trickle-charged the entire time; which will
have put only a small amount of energy into the Battery Pack. There may not be enough power to
ride safely. You should unplug the Segway HT, wait for the Batteries to stabilize within the
recommended temperature parameters, and then begin charging.
To maximize battery life and performance, follow this procedure to charge your new Segway HT.
Battery Packs before the first use and after the first five uses:
1. As soon as possible and before your first use, charge the Battery Packs
for at least 12 hours. Charging is best performed at room temperature.
2. Limit the duration of the first five uses of your Segway HT so that you do
not discharge the Battery Packs below the charge level illustrated at right:
3. After each of your first five uses, charge the Battery Packs for at least
eight hours.
In order to maintain the best performance from your Segway HT Battery Packs, charge your Battery
Packs for at least 12 hours once a month, or once every 12 hours of operation— whichever comes
first.
