Battery Charger Operation; On-Board Battery Charger - Pronto M50 Owner's Operator And Maintenance Manual

New batteries MUST be fully charged prior to initial use of the wheelchair.
Always charge new batteries before initial use or battery life will be reduced.
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.
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.

Battery Charger Operation

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.
Use of improper extension cord could result in risk of fire and electric shock.

On-Board Battery Charger

When using an extension cord, use only a three (3) wire extension cord having at
least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating
as the device being connected.
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.
Three (3) prong to two (2) prong adapters should not be used. Use of three (3)
prong adapters can result in improper grounding and present a shock hazard to the
user.
