INTRODUCTUCTION
This charger is manufactured using the highest quality components, latest manufacturing
processes & systems, along with very strict quality control, to achieve the highest quality
levels in the industry.
Incorporating a unique micro-processor controlled eight stage charging system, This
system intelligently assesses battery condition, state of charge and size, and produces a
charge rate to suit the battery, making battery charging safer, faster and much more effective
in charging and maintaining a battery or small 12v battery banks.
A heavy duty switch to select battery voltage for the microchip controlled automatic eight
stage charging system, provides accurate detection, monitoring and control of the charging
output voltage and current in turn preventing serious over charge or short charging of the
battery. This prevents battery plate oxidization, evens the consistency of the battery
electrolyte, minimizes battery temperature rising while charging recovers the battery
capacity faster and extends battery life.
The “Lead-acid (AGM) / Calcium” or “Gel” selector switch alters the charging stage voltage
parameters allowing all types of batteries to be effectively charged and ready for optimal
use.
The Zero volt start allows the charger to be connected to very flat batteries, and along with
the Desulphation stage give these batteries the best chance possible in recovery.
Temperature compensated voltage adjustment automatically adjusts the charging voltage
according to the environmental ambient temperature. In summer, this function helps
decrease battery heat generated while charging, thus minimizing the loss of battery
electrolyte and preventing battery deformation caused by excessive heat during charging
cycles.
Whilst charging the battery, it is common to see the voltage and percentage of charge LED
display to fluctuate up and down. When a battery is first connected, voltages will climb well
over the selected voltage and later drop back down. This will have an effect on the
percentage of remaining charge display as the on-board software will calculate this figure
based on the battery voltage reading. After the battery charger finishes its bulk and
absorption stages, the charge voltages will slowly settle back down, thus giving an accurate
reading of remaining charge, so please allow appropriate time to gather an accurate reading
of percentage of remaining charge.
Intended Use
The SP61090 - 6,12, 24 Volt Battery Charger is ideal for the home handyman or small
workshop, designed to efficiently charge 6, 12 or 24 Volt lead acid automotive, Motorcycle,
marine and light industrial type batteries, Including Calcium-Calcium (Cal-Cal), Calcium-
Silver (Cal-Ag), Lead Antimony, Absorbed Glass Matt (AGM) and Gel battery types.
These chargers are intended only for use in non-explosive and dry environments.
Never use or put the charger down in any liquid, oil or water.

Operation
How to use:
1) Check the battery is suitable for this charger.
2) Select the correct battery voltage by rotating the Voltage selection switch.
3) Connect the charger Positive (Red) Lead to the Positive of the battery.
4) Connect the charger Negative (Black) Lead to the Negative of the battery.
5) Plug the charger into the power socket & turn on the charger.
6) Select the battery type by repeatedly pressing the battery type selector until the
correct type is illuminated on the display.
Gel = Gel Batteries, Lead Acid = Lead Antimony & AGM Batteries, Calcium =
Calcium (Ca-Ca or Ca-Ag)
7) Charging is now taking place.
8) When the battery capacity bar graph is fully lit up, the battery is fully charged & the
charger has gone into its maintenance stage. You can disconnect the charger, or
leave the charger connected, if left connected the charger will maintain the battery in
a fully charged state without causing any damage to the battery or charger.
Note: The charger will remember the last battery type selected, even after disconnection
from the power, and will only change when changed manually by the user. This is very
useful if you are charging a lot of batteries, or the unit is permanently connected to a
battery bank and the 240V power may be frequently disconnected and reconnected.
LED Display:
•Battery Type Selected – “GEL”, “LEAD
ACID”, “CALCIUM”
•Charging Voltage – Shows the Voltage
of the battery while charging.
•All bars on battery will flash if the
charger has determined that the battery
may be faulty.
The battery bar graph will display the percentage of charge in the battery, when all bars
are illuminated the battery is fully charged.

As well the red & white terminals
on battery bar graph display will
flash, if the charger is connected
to the battery with reverse
polarity.

Charging Stages:
Stage 1 – “Desulphation”
In this initial start-up stage, a high frequency voltage pulse (0.5 sec) is to assist in “waking
up” a deeply discharged battery. This method of pulse charging can also help to reduce
build-up of sulphate crystals that may have formed on the battery plates during the time it
was discharged. This stage will last as long as it takes the battery to reach approximately
10 volts. If the connected battery is only slightly discharged, this stage may only be
activated for a short time before automatically switching to the next “soft start” stage.
Stage2 – “Soft Start”
Most conventional Battery Chargers will immediately apply a high charging voltage and
current output. This creates a large amount of gas and heat from the battery, and when
the consistency of the battery electrolyte / state of cell charge is uneven and a full load
charging characteristic can result in a period of potentially damaging overcharging.
The Soft Start function eliminates this situation by starting the charging process slowly and
softly, battery electrolyte and cell charge is able to even out, before receiving the main bulk
charge. This significantly improves the battery charging capability and reception.
Stage 3 – “Bulk”
This is the main hard charging stage, where the charger will operate at the maximum rated
current output, until the battery reaches a pre-set voltage determined by the battery type
selection. Charging time period is determined by the capacity and charge state of the
battery.
Stage 4 – “Absorption”
After the Bulk stage, the charger will automatically begin to reduce its current output
depending on the charge acceptance of the battery, while maintaining a constant voltage
(determined by the battery type selection). When the current reduces to a predetermined
threshold level charging will automatically halt, allowing the analysis stage to be performed
Stage 5 - “Analysis” (Testing the battery while charging)
After the Absorption charging state, the battery charger will start the “Analysis” stage and
will stop charging the battery for approximately 2 minutes. At this point, if the battery
voltage is sensed at below 12.6V, the battery alarm and faulty battery indicators and alarm
will sound. If the battery voltage is equal to or above 12.6V, the next Boost stage will start.
Stage 6 – “Boost”
After successfully analysing the battery condition, the charger will enter the Boost charge
stage, which will charge at a slightly higher voltage ensuring the battery attains a 100% full
charge. The current output is limited at 25% of the maximum rated charger output. When
the current drops to the pre-set level or a maximum of 15 minutes is reached the charger
will enter the last float charge stage.
Stage 7 – “Float”
This stage will “even out” the voltage between all cells maintaining a constant voltage with
a reduced current, thus prolonging the battery service time. If a load is applied to the
battery and the battery voltage drops below 6.2 volts (6 Volt Setting), 12.4 volts (12 Volt
Setting) or 24.4 volts (24 Volt Setting), the charger will restart from the absorption stage.

6
Stage 8 – “Maintain”
This final stage regulates the fully charged battery. A small pulse charge is applied at
0.5Hz to maintain the battery at its fully charged state and ready to be used at any time. If
a load is applied to the battery and the battery voltage drops below 6.2 volts (6 Volt
Setting), 12.4 volts (12 Volt Setting) or 24.4 volts (24 Volt Setting), the charger will restart
from the absorption stage.
