SECTION 9—BATTERIES
The amount of electrical current drawn within a given time to charge a battery is called “charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is high. As a charge builds up, the charge rate is reduced, and the battery charger rate decreases to a “trickle charge”.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they may need to be replaced. Contact a qualified technician.
NOTE: The batteries can be charged using the on‐board battery charger or by plugging an independent battery charger into the port located on the front of the joystick.
Battery Charger Operation
DANGER
Use of improper extension cord could result in risk of fire and electric shock.
WARNING
Read and carefully follow the manufacturer’s instructions for each charger (supplied or purchased). If charging instructions are not supplied, consult a qualified technician for proper procedures.
NEVER leave the charger unattended when the charger circuit breaker is tripping.
On-Board Battery Charger
DANGER
When using an extension cord, use only a three wire extension cord having at least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating as the device being connected. Use of improper extension cord could result in risk of fire and electric shock. Three prong to two prong adapters should not be used. Use of three prong adapters can result in improper grounding and present a shock hazard to the user.
WARNING
Ensure the pins of the extension cord plug are the same number, size, and shape as those on the charger.
DO NOT, under any circumstances, cut or remove the round grounding plug from the charger AC cable plug or the extension cord plug.
NOTE: For this procedure, refer to FIGURE 9.6 on page 60.
NOTE: The On/Off LED indicator light and the charger LED indicator light are located on the top of the charger on the rear of the wheelchair. Open rear shroud to view indicator lights.
NOTE: If the batteries are completely discharged, the charger will not charge them. Replace the batteries. Refer to Removing/Installing Batteries from/into Battery Tray on page 53.
