Battery Information
9. Battery Information
9.1 Battery type
Each lift unit is equipped at the factory with two deep
cycle batteries. These batteries have been selected to
match the usage conditions found on the lift unit. If
replacement batteries are needed, it is recommended to
use only the same brand and model of batteries originally
supplied with the lift unit.
Do not mix old and new batteries or use different
types/brands of batteries on the same lift unit.
9.2 Charging the batteries
The batteries should be charged after each use to ensure
the longest possible battery life and to avoid service
interruptions. The batteries used on all models can be
charged before they are completely discharged and not
develop a “memory”. The battery life and level of charge
will be greatly improved if the batteries are charged before
they are deeply discharged.
NOTICE:
Only use the supplied battery charger to
charge the batteries. The supplied battery charger is
designed for the type of batteries used on the lift units.
Use of a charger not designed for the type of batteries
on the lift units may cause under or overcharging that
will reduce the life and capacity of the batteries.
The on-board battery charger is mounted inside the
sheet metal cabinet above the door as shown in Fig.
16. A cord reel is provided with every lift to assist in
connecting the battery charger to AC power. If not
already installed, follow the instructions provided with
the cord reel to mount it on the left side of the lift unit.
To charge the batteries, extend the cord from the
cord reel and plug into an appropriate wall outlet. The
cord is approximately 25 feet long when fully extended.
If needed, an extension cord (see the table in the
column for proper selection) can be used to extend
the reach of the cord reel. Always use a grounded
extension cord with a plug style that matches the
plug from the cord reel. Inspect the condition of every
cord and plug and only use if they are free of defects.
The amperage drawn by the battery charger is shown
in the table below. Four lift units (in any combination
of models) should be able to charge simultaneously on
the same circuit powered by a 20 Amp circuit breaker.
The battery charger provided on each lift unit and the
Touch Screen Controller is a “smart” charger. The battery
charger automatically goes through several different
stages of charging to properly charge the batteries. The
battery charger can be left plugged in indefinitely without
harming the batteries.

The battery charger provided on each lift unit is a “smart”
charger. There are two sets of battery charger indicator
lights (one for each battery) located above the door that
indicate the status of the battery charger when it is
plugged in (Fig. 16). The battery charger automatically
goes through several different stages of charging to
properly charge the batteries and can be left plugged in
at all times without harming the batteries. A series of
red lights will illuminate to indicate the charger is charging
the battery. As the battery is charged more red lights will
illuminate to indicate the status. A flashing green light
means the battery is at least 90% charged. A solid green
light indicates the battery is fully charged and the charger
has switched to its maintenance mode. If multiple
flashing lights are observed an error condition exists. See
troubleshooting table on the next page for help to fix the
error condition.
