PBC88S and PBC168S Battery Charger procedure notes:
1. These battery chargers all use the eight stage charging process. The charging time of
each stage depends on the size of the battery and the capacity of battery. An in-
depth explanation of each stage is shown below.
2. These battery chargers all have protection systems installed.
If the 12V output clamps come into contact, there will be no safety issues.
If the two clips are connected to the battery in reverse polarity, there will be
no problems, apart from the battery not charging.
If the 12V clamps are connected to a 24V battery, there will be no problems.
If the charger is connected to the battery longer than necessary, the battery
will never be overcharged.
This charger has a built-in temperature control system, in the case where the
temperature rises above 55 degrees Celcius, the temperature control system
will reduce the output power until the temperature drops to safe levels
There is a safety fuse installed within the unit, and is not accessible from the
outside the battery charger.
3. This charger can automatically select GEL, AGM and Lead Acid batteries for charging,
however, if battery that needs to be charged is Calcium or silver/calcium type
battery, you must set this option manually by holding the button on the front panel
for 3 seconds, which will make the Calcium LED show up on the screen, hence,
beginning the charge mode for Calcium type batteries.
4. This unit also has a DC power supply mode. If you double click the button on the
front panel, the DC supply LEDs will light up on the screen. The clamp can then
output 13.5V, 8Amp or 16 Amp for your 12V DC electrical appliances. The DC output
mode has short circuit and overload protection. If something goes wrong, simply
restart the system.
5. The front LED screen display shows:
Percentage of charged battery capacity.
Battery terminal LED light that illuminates in order to warn user about a short
circuit or reverse polarity.
Faulty battery indicator.
Calcium battery selected or DC supply selected.

8 Stage Charging process:
Our chargers are specifically designed with the ability to start at 0V, which means that if the
battery has been drained to zero volts, the charger can still charge the battery voltage back
up to 8V, provided the battery is not faulty. During this initial start-up stage, the charger
uses frequency voltage pulses which assist in “waking up” the discharged battery. This
method of pulse charging helps reduce the 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 until the battery reaches approximately 8 volts. If the connected battery is only
slightly discharged, this stage may last a short time before automatically switching to the
soft stage. However, if the battery is unable to charge up to 8V after 30 minutes, this
indicates that the battery is faulty, which will illuminate the “faulty battery” LED screen on
the battery charger.
During this stage, output voltage will be pulsing at 13V at 0.1Amp.
After the battery is connected, most conventional “Smart” battery chargers will immediately
apply a high charging voltage and current output. This produces a large amount of gas and
heat which is generated by the battery and can cause individual battery cell voltages to be
uneven. Uneven cell voltages can cause individual cell overcharging or undercharging,
lessening the overall life span of your battery. The soft start function counteracts this issue
by starting the charge process slowly. Battery electrolyte and cell voltage is given a chance
to even out prior to the main bulk charging processes, greatly increasing the battery’s
During this stage, output voltage is 13V at 2.5A or 5A.
This is the main charging stage, where the charger will operate at its maximum output
current and voltage until it reaches the required level of charging. This level of charging will
be indicated during the battery type selection process using the chemistry selection button
on the charger. (IMPORTANT: different types of batteries use different chemistries within
the batteries and thus have different maximum voltage levels for charging). The charging
period of this stage is determined by the capacity and charged state of the connected
battery and will vary between different battery types.
During this stage, the charging voltages are as follows:
1. Gel, AGM, Lead Acid Battery: 14.5V at 8A or 16A.
2. Calcium Battery: 15.2V at 8A or 16A.
After the bulk stage, the charger will start to automatically reduce its current output while
maintaining the required voltage (depending on the chemistry of the battery). When the
current reaches a predetermined threshold level, charging will halt allowing the next
analysis stage to be performed.
At this stage, the charging voltages are as follows:
1. Gel, AGM, Lead Acid Battery: 14.5V, current slowly drops down to 1.5A~2A.
2. Calcium Battery: 15.2V, current slowly drops down to 2A~3A.
Analysis (Testing the battery whilst charging):
After the absorption stage, the battery charger will begin the analysis stage and will stop
charging the battery for approximately one minute. At this point, if the battery voltage
drops too quickly below set parameters, the battery error indicator will illuminate, which
indicates that your battery may be faulty. If this occurs, please see your local auto
electrician to have your battery evaluated. If the battery passes this test with no issues
detected, it will then move to the boost stage.
During this stage, charger will have no output for one minute, if battery voltage drops lower
than 12.6V, the “faulty battery” light will turn on and also emit a beeping sound. If the
battery passes this test with no issues detected, it will then move to the boost stage.
After a successful result from the analysis stage, the charger now enters the Boost stage
where voltage is increased to maximum and the current is reduced to approximately 25% of
the rated output. This stage charges the battery safely up to a 100% fully charged state.
During this stage, charger will output a pulse voltage:
1. Gel, AGM, Lead Acid: 15.2V
2. Calcium: 16.5V
The frequency of the pulse depends on the how charged the battery is. If battery is not
charged by a large amount, the pulse frequency is fast and the average charging current is
large. If the battery is almost full, the pulse frequency is slow and the average charging
current is small. When average current drops to 1A~2A or approximately 2hours has
elapsed, it will move onto the next stage.
This stage supplies a constant voltage to the battery in order to counteract the temperature
increase and self-discharge of the battery.
The charger output voltage during this stage is as follows:
Gel, AGM, Lead acid: 13.5V
The current output is negligible as it is very small. After 2 hours has elapsed, the charger will
move onto the next stage.
This stage evens out voltage between all cells and will maintain a constant pulse voltage
with a very small current. This stage will remain on indefinitely while the battery is
connected and is perfect for long term maintenance for vehicles or stand-alone batteries
that will not be used for long periods of time such as winter storage. Keeping your battery
on the maintenance stage while charging will ensure it is always 100% charged and will
reduce the chances of sulphation, extend battery life and improve serviceability. During long
term maintenance, it is important to periodically check fluid levels in the battery if it is NOT
a sealed or maintenance free design.
The charger output voltage values are the same as the previous stage, but will now become
