Operating the Maxi 500
Battery Charging
The Maxi 500 uses sealed lead-acid batteries
mounted within the control box. Unlike nickel-
cadmium batteries, lead-acid batteries are not subject
to a memory effect. Therefore, they should not be
completely drained before being recharged. The
control box is equipped with an automatic control
shut-off after 20 seconds of inactivity to prevent any
battery drainage while the lift is in the stand-by
mode. Power to the lift is reactivated by pushing any
hand control button. The lift also has a battery
discharge indicator, located on the cover above the
battery.
It is recommended that the battery be removed from
the lift when it is not used for an extended period of
time, and recharged when the battery discharge
indicator displays amber.
To prolong the battery pack life, recharge it before it
reaches a low state of battery charge, and certainly
before it is totally discharged.
Your lift is equipped with an audible warning device,
which will make a noise when the battery discharge
indicator reaches the red light range.
To ensure that the Maxi 500 is always ready for use,
it is recommended that a fully charged battery pack
always be available. Do this by having additional
battery packs available and keeping one charging
while the other is in use.
When a fully charged battery is inserted into the lift,
the display will return to the green fully charged
position, regardless of the level the indicator had
reached previously. However, if a partially charged
battery is inserted, the previous indicator level will
be maintained, even though the recently inserted
battery may be in a better state of charge than
indicated. To achieve a true indication of battery
condition, a fully charged battery must be inserted
into the lift. This will reset the indicator.
When using the battery charger for the first time, or if
the cable has been unplugged from the charger,
connect the cable fully into the charger before
connecting to the main electrical socket.
CAUTION:
Batteries need to be charged for a mini-
mum of 8 hours prior to initial use of this
lift.
Place the battery pack on the charger as follows:
1
When the LED on the battery discharge indicator
displays amber, complete the lift/lower cycle.
Then, take the lift to a convenient location and
remove the battery pack by holding it securely,
depressing the button at the top of the battery
pack, then pulling it out carefully.
2
Insert the battery pack into the charger unit and
push it firmly. The charging connector will auto-
matically connect, as there is no on/off switch.
Then, turn on the power.
3
A red LED indicator will light up. A solid light
indicates that the charger is working. When the
light is flashing, the battery has finished charg-
ing. Disconnect the main plug from the supplied
socket when the charger is not in use.
4
A discharged battery should take approximately
eight hours to fully recharge.
5
When the battery pack is fully charged, discon-
nect it from power, remove the pack from the
charger, and insert it back into the Maxi 500. An
electrical connection is made automatically.
6
Press the green Reset button. The Maxi 500 is
ready for use.
