Chapter 6 – Batteries
The battery tray contains four, 6 volts 225ah batteries.
These batteries supply 24 volt DC electrical power to
operate the aerial platform control systems. Proper ma-
chine operation depends on well maintained and charged
batteries.
General Maintenance
Always keep the batteries clean, free of dirt and corrosion.
A film on top of the battery can accelerate discharge.
Warning
Battery acid can damage the skin and eyes. Serious
infection or reaction can result if medical treatment is
not given immediately. Wear face and eye protection
when working near the batteries.
Use distilled water to refill the batteries. Avoid water
containing metallic solids such as iron which can reduce
the life of the batteries.
Consult a battery charger specialist if extreme tempera-
ture use is unavoidable.
y
Cold reduces battery capacity and retards charging.
y
Heat increases water usage and can result in over-
charging.
y
Very high temperatures can cause thermal run away
which may lead to an explosion or fire.
Charging
The aerial platform is equipped with a manual plugin bat-
tery charger that will completely recharge the batteries.
Warning
Batteries give off hydrogen and oxygen that can com -
bine explosively. Death or serious injury can result
from a chemical explosion. Charge the batteries only
in a well ventilated area away from sparks or flame.
It may take from 1 1/2 to 16 hours to recharge the batteries
depending on the amount of discharge. If the charging
cycle exceeds 16 hours without the batteries being fully
recharged, shut off the charger and have the batteries
checked.
Fully recharge the batteries, immediately after use.
y
One charging cycle per day is preferred.
y
Fully charged batteries perform best.
y
The deeper the discharge, the fewer number of cycles
a battery will deliver. Deep discharges deteriorate the
battery quicker than light shallow cycles.
y
An overly discharged battery may need to be cycled
a few times before it can fully recover.
y
If a battery begins to heat before becoming fully
charged, it may be necessary to recharge and dis-
charge the battery a few times.
Use the following procedure to charge the batteries.
1. Check the battery water level. Add water to indi-
vidual cells only if the plates are exposed. Replace
the battery caps.
2. Plug the charger into a properly grounded AC outlet
using a 3 conductor, 12 gauge or larger extension
cord. The extension cord must be as short as pos-
sible and in good electrical condition.
3. Leave the charger plugged in until the batteries are
fully charged.
4. Unplug the extension cord after turning the charger
off. Allow the batteries to cool off after charging.
5. Check the battery water level. Add water to indi-
vidual cells only if the plates are exposed. Replace
the battery caps.
