Друкувати сторінкуOn a single battery just connect the red to positive and the black to negative. If you are fitting to a
battery set you will need to identify the first and last battery in the pack. In most cases this is a
simple matter of identifying the terminals that the battery charger is connected to, then attaching
the BE red to positive, black to negative.
The BE can be permanently mounted using screws and nuts, self tapping screws or tie wraps. We
recommend that you mount the BE to a metal surface to help dissipate heat from the unit.
Now all you have to do is leave the connected at all times, during charging and discharging, just
use your battery pack as normal.
RECOVERING SULPHATED BATTERIES
Recovering sulphated batteries is a gradual process. You have to cycle (charge, discharge) the
batteries, with the BE connected, and make sure you never leave the batteries in a discharged or
part discharge state. Depending on how badly sulphated the batteries are, and the size of the
battery pack, this could take anything from a few cycles to more than 20.
If your batteries have not been used for some time, or are very heavily sulphated the battery
voltage may have dropped so low that your modern smart battery charger just thinks the battery is
no good, and will not charge them. These batteries can often still be recovered. One method, for
12 volt batteries, is to use an old type manual charger or regulated low voltage (14 or 15 volts)
power supply that can trickle charge the battery with the BE connected, and with the low voltage
cut off set to the off position, this will enable you to monitor the battery voltage until it reaches at
least 12 volts. Depending on the size of the battery this could take from one day to several days.
Repeat this process if you have more than one battery in the pack, Once you have recovered all of
the batteries in the pack, connect the pack to your regular charger, switch the BE to the, "low
voltage on" position, and cycle the pack. Another method is to connect the sulphated battery in
parallel with a known good battery, this will often be enough to kick start the bad battery. If any of
the batteries in pack fail to respond and still show low voltage discard those batteries and replace
with batteries of the same make and size.
Lead acid batteries are made up of 2 volt cells, so a 6 volt battery has 3 cells and a 12 volt battery
has 6 cells, in most cases of battery failure only one cell needs go dead for a battery to fail.
THE MAIN REASONS FOR FAILURE
(1) A sulphated cell, a build up of lead sulphate on the plates which weakens the acid and
increases the internal resistance of the cell until it can no longer produce energy. The Battery
Extra dissolves the lead sulphate back into the acid solution and stops further sulphate build up.
This significantly extends the life of the battery.
(2) A shorted cell, generally due to shedding of lead particles from the plates building up at the
bottom of the cell, which makes a circuit between the positive and negative plates causing a short
circuit. The Battery Extra slows down the shedding by eliminating the sulphate build up, but it
cannot repair a shorted cell
(3) An open circuit, caused by a connection point in the cell burning out, this is normally the result
of overcharging the battery. The Battery Extra can do nothing to stop this. If you batteries are
getting very hot when charging, this can be an indication of overcharging. Modern battery chargers
will normally revert to a trickle charge when the battery is fully charged. If you have a BE fitted this
will be indicated by a drop in the voltage shown on the unit. If you do not see this voltage drop,
check you charger.
