to one which is being used, preferably to
the one with the heaviest work load.
failure to do this will result in reduced
performance of the product,
charger operation 4 step charge:
this unit is a battery charger/powerpack,
its first job is to charge the batteries,
upon switching the charger on the
orange l.e.d and green ( or yellow
depending on battery type ) comes on to
show the charger is on full current (
constant current charge step 1 ) when
the batteries reach 14.4 or 14.8 (
depending on battery setting switch ) the
orange l.e.d. will go out and the lower
green l.e.d will come on ( the upper
yellow/green will remain on as well step
2 ) this shows the charger is on
equalizing charge, ie at constant voltage
at 14.4 or 14.8, the equalizing charge
time will depend on the position of the
timing switches. after the equalizing
time is complete, the charger top led
will go off leaving only the lower green
l.e.d., this shows the charger is at
constant voltage at 13.5 volts ( power
pack mode step 3 ). on this mode the
charger will supply its full current if
required to maintain the power supply to
the boat without using the batteries, in
the event of the batteries being
discharger below 11.5 volts ( step 4 )the
charge sequence starts all over again.
The good the bad and the ugly
about batteries.
this is a list of questions and blunt
answers about marine batteries and
battery charging in the form of common
questions and answers. there are so
many old wives tales about this subject
that these questions are compiled from
my interaction with the public in the
last 5 years at international boat shows
Downloaded from www.Manualslib.com manuals search engine
around the world.
the biggest problem in the marine
world is that the public expect the same
solution for all boats , most equipment
is sold as leisure rated equipment, the
larger boat owners who should be using
commercial equipment should not be
surprised with some of these answers,
How long will my batteries last?
this is a very difficult question, in a
nutshell the less you use the battery the
longer it will last, never fully discharge
a battery and always plug in the charger
power pack where ever possible,
remember that the batteries and set up
on most boats from 20-40 ft are for
leisure, if you use the boat for leisure
purposes ie 3-4 weekends per month for
7 months plus 1 x 2 week period in the
summer then expect about 3-5 years out
of the average leisure type battery.
however if you have a crew onboard, or
live onboard, expect about 3-5 months
use out of the same batteries ( in this
case do not blame the batteries, blame
the idiot who fitted a leisure battery in a
commercial installation )
What is the best battery type?
the answer to this is very much based
on the above, for the average leisure
user the best value is the conventional
leisure ( sometimes called deep cycle
but this is a myth ) battery, available at
most chandlers, they will offer you 3-5
years trouble free operation, however if
you think you are going to use these
batteries and give them a heavy duty
cycle then the only person you are
kidding is yourself.
for live on board, crewed, 40 ft plus,
blue water yachts, electric hungry boats
with large inverters, there is only one
option, use what the professionals use,
