back up at short intervals). This is perfectly
normal and will not cause damage to either
charger or battery. However, if the circuit
breaker continues to operate for a period
in excess of 4 hours it is possible that the
battery is faulty and should be checked
with a hydrometer or by an automotive
electrician.
CHARGING THE BATTERY
Boost Charging
The ‘Boost’ mode has been designed to
automatically charge batteries to a higher
float voltage than the ‘Automatic’ mode
and in many cases a battery will be able
to start a car after only a short period of
charging.
CHARGING BATTERIES IN GOLF
BUGGIES, WHEELCHAIRS, ETC,
USING ‘BOOST’ MODE
The ‘Boost’ position is ideally used for
charging batteries which are used on
a daily basis (e.g. wheelchairs), or for
situations where the battery is used
several times a week such as in golf
buggies. Batteries used for these
applications should be recharged after
each use. Typically the batteries will be
charged after 12-15 hours when using
the ‘Boost’ mode (based on charging
30 ampere wet cell battery used in golf
buggies).
This procedure is not recommended for
sealed/low maintenance batteries, the
charger should be switched over to the
‘Automatic’ mode until the charging
program is completed.
When charging batteries in the ‘Boost’
mode do not charge for longer than 24
hours, as overcharging may occur.
Generally a battery in good condition
which has reached a fully charge state,
should not have any noticeable decrease
in its state of charge when stored for a
couple of weeks.
Batteries only partially discharged, or
batteries of smaller capacity may only
require charging for a few hours in
‘Boost’ mode.
AUTOMATIC CHARGING
In this mode the charger automatically
reduces the charging current as the
battery becomes charged and thereafter
provides just sufficient current to maintain
the battery in a charged condition.
Consequently, batteries may be left on
charge continuously for long periods
without risk of damage resulting from
over charging.
This feature is ideal for charging most
sealed batteries and is particularly useful
for batteries which are installed in boats,
golf buggies, caravans or lawn mowers
where they are only used intermittently.
WARNING
Batteries of the non-sealed type emit
hydrogen gas when in use. This is known
as ‘gassing’. Hydrogen ignites explosively
in confined spaces so never approach
battery cells with a naked flame or cause
sparks in the vicinity of the battery.
Sealed or low maintenance batteries do
not gas so noticeably a ordinary batteries.
Nevertheless, the usual safety precautions
should still be observed.
Please always adhere to battery
manufacturer’s recommendations when
charging batteries.
