BATTERIES

General

Stair-Trac is powered by two 6-volt sealed batteries. These cells are spill-proof,
maintenance-free and rechargeable. Power capacity under a full load while travelling
upstairs is about 650 stairs or approximately 30 minutes on a full charge.

Charging Batteries

The Battery Charger is used to charge the Stair-Trac batteries from the mainline (120
VAC) supply. Your Stair-Trac comes supplied with a 12 volt Charger designed for
sealed batteries. It features the maximum recommended 4 amp charge rate and will
automatically switch to a trickle-charge rate when the batteries are close to fully
charged. At this point the Charger may be left connected indefinitely without damaging
the batteries. The trickle-charge feature is important to prevent over-charging of the
batteries and to help prolong their life.
Charging time will vary depending on battery use, but should not require more than
eight hours.
Caution: Use of unauthorized chargers may cause damage to the batteries. If a
substitute charger is used, ensure that it features a dual-mode automatic cut-off. Do not
use a lead/acid battery charger.
To use the Battery Charger:
1. Disconnect the Stair-Trac cable from the battery pack.
2. Connect the Battery Charger cable to the battery pack.
3. Plug the Battery Charger into a 110 VAC power supply.
