Batteries
The MegaDumper is fitted with four 12V/20Ah deep-cycle gel VRLA batteries in two parallel
series circuits to deliver 24VDC (nominal) to the motor and control circuits.
The batteries are sealed and maintenance-free, with a nominal lifespan of five years.
However, battery life is dependent on several factors, including the number of charge
cycles, the average discharge depth, and environmental conditions.
4.5.3.1
Charging the batteries
To recharge the batteries, plug one end of a 1-phase extension lead into the appliance
socket on the machine, and the other end into a 1-phase mains power outlet.
A full charge usually takes about 10 hours. The machine can be used while on charge.
The battery 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 a 200kg bin in about 5 minutes, which
means that in most cases a battery machine can be operated as a 1-phase mains
machine (see duty cycle table in
4.5.3.2
Maximising battery life
Observing the following rules can help to maximize the life of the batteries:
-
Place the batteries on charge every night (not just when they are flat).
-
Do not allow the machine to sit with flat batteries for more than 24 hours.
-
Do not operate the machine when the voltmeter reads less than 24V.
Batteries are supplied with a 12-month warranty, separate from the warranty on the rest
of the machine.
Battery charger
The MegaDumper is fitted with a digital smart charger which accepts 1-phase mains power
at 85-264VAC (multi-voltage) and 50/60Hz, with a maximum current draw of 3 Amps.
The charger outputs up to 6 Amps of continuous direct current at 27.2 Volts, for a maximum
power output of 160 Watts.
The battery charger is in an enclosed plastic case and is protected against short-circuit,
current overload, over-voltage, and over-temperature conditions.
Battery box
The MegaDumper batteries are contained in a separate battery box, which is mounted
beside the main enclosure and connected to the powerpack with a 175A Anderson plug.
This allows the battery box to be quickly removed for offsite charging, or multiple battery
boxes to be charged and swapped for 24/7 operation.
