When To Charge Batteries; Spj+ Joysticks - Invacare Pronto M94 Owner's Manual

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.
