SECTION 11-BATTERIES CAUTION As a general rule, you should recharge your batteries as frequently as possible to assure the longest possible life and to minimize required charging time. Plan to recharge them when you DO NOT anticipate using the wheelchair. Some basic concepts which will help you understand this automatic process are: 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. When to Charge Batteries SPJ+ Joysticks NOTE: For this procedure, refer to FIGURE 11.4. The Information Gauge Display located on the front of the joystick housing, it provides the state‐of‐battery charge, including notification of when the battery requires charging. It also provides the following information to the user on the status of the wheelchair: A. GREEN LEDs are lit, indicating well charged batteries. B. AMBER LEDs are lit, indicating batteries are moderately charged. Recharge batteries before taking a long trip. Batteries Empty Information Gauge Display Batteries Full C. RED LEDs are lit, indicating batteries are running out of charge. Recharge batteries as soon as possible. Battery Charger/ Programming Port FIGURE 11.4 SPJ+ Joysticks Part No 1122145 75 Pronto® M94™

recharge them when you DO NOT anticipate using the wheelchair.
Some basic concepts which will help you understand this automatic process are:
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.
