5.4 Electrical System (battery)
If you do not operate a battery-powered machine, please disregard this section.
Standard battery-powered machines are fitted with two deep-cycle sealed gel batteries, a
digital smart charger, and a series-wound 24VDC motor. The control voltage is 24VDC.
The motor only runs when the RAISE button is pressed; the cradle is lowered by gravity alone.
As a rule, one full charge is sufficient to empty 10 tonnes of material, but this is dependent on
the tipping height and the condition of the batteries.
5.4.1 Localisation
The digital smart charger fitted to battery machines automatically adapts to a range of
different input voltages and phase frequencies. This means the machine can be charged
using standard 1-phase mains power in almost any country around the world. A power plug
adapter may be required in some cases.
5.4.2 Voltmeter
Battery machines are fitted with a digital voltmeter on the control panel, which is used to
indicate the charge level of the batteries. As shown on the markings
, when the voltmeter
reads less than 24 volts the batteries are flat. The machine should not be used and should be
placed on charge as soon as possible.
Because the voltage will fluctuate when the machine is operated, the charge level
should be checked while the machine is at rest.
Attempting to operate a machine with flat batteries may cause the overload fuse on the
battery cable to blow (see
Section 5.4.8) . It may also damage the batteries.
5.4.3 Battery charging
To recharge the batteries, connect an extension lead into the appliance socket on the right-
hand side of the machine, and into a regular 1-phase power outlet .
The maximum current draw of the charger is 3 Amps, and a full charge from flat normally
takes 8-10 hours. The machine can be used while on charge.
The onboard smart charger automatically adapts to different input currents, manages
the charging cycle to maximise battery life, and prevents overcharging.
The charger delivers enough power to empty one bin in about 3 minutes, which means
that a battery-powered machine left permanently on charge can often be used in place
of a 1-phase mains-powered machine (see
Section 2.5 ).
