MAINTENANCE
AGM BATTERY CHARGING
To maximize the life of your AGM battery, it is important
that it is properly charged. As with all lead-acid batteries,
both over- and under-charging an AGM battery will result
in
shortened service life
. The AGM batteries are sealed
for life units and do not require any fluid top up.
Figure 32. Battery Series Connections
The EB500 Mini Dumper is equipped with an on-board
SMART charger (Figure 33) which maintains the battery
full charge condition without resulting in over charging.

Charging System Inspection
The charger's AC power cord should be free of breaks
or cuts and the wall plug socket should be clean and
free from debris.
The cable connectors from the on-board charger should
be clean and properly mate with the battery terminals to
ensure a sound connection.
Battery Inspection
Check battery cables are not damaged.
Connectors should be free of corrosion.
Make sure battery cable post or eyelet connectors are
tight to avoid arcing.
Charging Guidelines
When the batteries have been discharged to
¼ full
as
indicated on the battery gauge it is time to have the
batteries fully charged. Plug the on-board battery charger
power cord into a 240 VAC power outlet.
Allow batteries to complete a full charge and
do not
disconnect until fully charged
. Once fully charged, the
on-board
SMART
battery charger will indicate a
GREEN
status light indicating that the batteries are fully charged.
DO NOT
charge batteries i.e. if the batteries have only
discharged to
¾ full
as indicated on the battery gauge.
There is no need to connect the battery charger power
cable to the AC power outlet.
It is recommended to use the Mini Dumper until the
batteries have discharged to
¼ full
as indicated on the
battery gauge, then place the batteries into a full charge

cycle.
ALWAYS
charge batteries in a well ventilated area as
gasses (fumes) may be released through the pressure
relief valve if the batteries are excessively over-charged.
NEVER
charge a frozen battery.
Ideal charging temperatures: 32°F to 104°F (0°C to 40°C)
