Prolonged operation in excess of the
maximum ratings may cause the over-
loads to operate, switching the charger
output off. If this occurs, switch off the
charger and allow it to cool. The overload
will automatically reset and allow charging
to continue. However, if the thermal
overload repeatedly operates, it is possible
that the battery is faulty and should be
checked with a hydrometer and/ or Hella
Battery Tester, Part No. 7100.
The charger is also provided with fuse
protection in the input circuit, which will not
blow in normal operation. If the fuse blows,
replace only with a fuse of identical type
and rating.
Repeated fuse blowing indicates a
possible fault in the charger. In these
circumstances, you should contact an
authorised service agent.
CHARGING RATE (HI/LO)
The recommended charging rate for most
batteries is 100% of rated capacity. This
means that a 50 amp-hour battery would
normally be charged at 10 Amps for
10 hours.
Occasionally it may be necessary to charge
at a higher current in order to reduce
the charging time. A rough guide can be
calculated by dividing the rated capacity of
the battery by the continuous current rating
of the charger, e.g. a 60 amp-hour battery
requires 6 hours at 10 Amps.
BANK CHARGING
Several batteries may be charged
simultaneously by connecting each of them
in parallel with the charger, using separate
jumper leads for the purpose.
Charging time can be calculated by adding
the individual capacities of the batteries
in the bank and dividing this sum by the
continuous current rating of the charger.
Hi/ Lo setting may be used according
to requirements.
LOW MAINTENANCE
BATTERIES
The characteristics of low maintenance
batteries are somewhat different from
those of ordinary lead-acid batteries.
When fully charged, the low maintenance
battery does not gas as noticeably as
ordinary batteries. Nevertheless, the
usual safety precautions should still be
observed.
SAFETY INFORMATION
WARNING
Working in the vicinity of a lead-acid
battery is dangerous due to the emission
of explosive gases. These explosive gases
can be ignited by a spark, cigarette or
naked flame such as a cigarette lighter or
matches.
•
Keep sparks and naked flames away
from battery at all times.
•
Never smoke or light a cigarette near
a battery.
•
Take extreme care with metal objects
and tools including items of jewellery
such as rings and watch bands. Metal
objects touching the battery terminals
may cause sparks or serious heat
burns to the user or wearer.
•
Do not allow tools to drop on the
battery and never temporarily place
tools on top of a battery.
•
When testing or working on or around a
lead-acid battery it is advisable to wear
protective eye glasses.
•
When testing or charging a lead-acid
battery, ensure that the area you are
working in has plenty ventilation. Never
test or charge a battery in a confined
area.
•
Do not use the charger in rain
or expose it to water from hoses or
sprinklers.
Lead-acid batteries contain Sulphuric Acid.
