4. Troubleshooting
If FAB does not activate it may be due to one of the following or a combination:
• Unit connected incorrectly (reverse polarity) – change the wires to the correct terminals.
• Bad connection – clean and tighten connection terminals of FAB unit.
• Battery has a short – have an electrician inspect the problem.
• Battery voltage is below the activation voltage – change to mode 1 constant or recharge the battery.
• 5 amp blade fuse on positive cable is blown, open fuse holder and replace blade fuse.
5. Warning
• FAB is supplied with wires 400mm in length. The (Black) negative wire only can be extended up
to a max. of 700mm so when the cables are spread apart they will reach terminals 1.5m apart.
• If checking state of health of multiple individual batteries, allow a cooling down period of 30 sec
between each test to avoid damage to unit and voiding of warranty.
6. Important
• Ampere Hours (Ah) is the rating for reserve capacity for auxiliary applications and is not to be
confused with Cold Cranking Amp (CCA) the rating for engine starting applications.
• Although FAB will help reduce electrolyte boil-off, levels should be checked monthly.
• Always use caution and wear protective clothing and eye protection when working with batteries.
• Ensure unit is fi xed clear of any moving parts and wires are zip tied to avoid damage.
• Do not use solvents to clean the unit.
7. Warranty
• Megapulse
• The warranty is not transferable and does not restart if and when a faulty unit is replaced.
• The warranty does not cover misuse, accident, alteration or abnormal operation.
• No warranty exists for usage outside specifi cations.
• For warranty replacement return faulty units to a Megapulse reseller with proof of purchase.
TM
warranty covers defects in workmanship and materials for 7 years from purchase date.
8. For Applications Using 6v, 36v & 48 volt
• The red LED when used on the above voltage applications indicate that the battery has the
reached 80% depth of discharge and should be recharged immediately.

Installation & User Guide
Congratulations on purchasing the most
effective technology available today for
obtaining maximum performance & maximum
service life from your Lead-Acid batteries.

Pulse technology
MegapulseTM FAB is not a charger, it is a proven electronic device using a patented Pulse Technology
to help batteries work harder and last longer by preventing a common cause of premature battery
failure ‘Sulphation build-up on the battery plates’. Pulse Technology has been independently tested
and proven by respected scientifi c organizations around the world to be an effective remedy against
Sulphation. Pulse Technology has also been in Military use since 1974.
How to install MegapulseTM FAB
1. Simply install the FAB cables onto the positive and
negative battery terminals of a single battery or a battery
bank (refer to diagrams in section 3).
2. FAB will start de-sulphation of battery or batteries immediately
after the installation and commissioning sequence has completed.
3. Secure FAB with screws near the battery or use a Nylon zip
fastener to secure FAB to the battery or battery cables.
What you will see after installing FAB
• FAB will go through a commissioning and battery load test sequence,
where it will establish the health of your battery (12v & 24v applications only).
• The battery load test will then be repeated every 21 hours (12v & 24v applications only).
• FAB will go through a commissioning and battery voltage test sequence, where it will establish
the depth of discharge of your battery ( 6v, 36v & 48v applications only).
• The battery voltage test will then be carried out every 30 seconds so that the state of
charge is continually monitored (6v, 36v & 48v applications only).
• After activation FAB will fl ash either Green or Red depending on the result of the relevant
battery tests mentioned above.
What do Green LED fl ashes mean?
• Repeated Green LED fl ashes (12v & 24v applications only) mean your battery successfully passed
the load test and will be maintained in peak condition by having FAB permanently installed.
• Repeated Green LED fl ashes (6v, 36v & 48v applications only) mean your battery is in a charged state.
• If you move FAB to other batteries, make sure it is installed for a minimum period of 6 weeks.
Megapulse_User_Guide indd 2 27/4/11 10 59 24 AM
What do Red LED fl ashes mean?
• Red LED fl ashes (12v & 24v applications only) mean ‘check battery’, (refer to the list of
items to check below).
• Red LED fl ashes (6v, 36v & 48v applications only) mean that the battery or battery bank
is discharged to 80% and must be recharged immediately.
• FAB restores lost capacity due to sulphation within a minimum period of 6 weeks providing
the battery is mechanically sound.
Factors resulting in Red LED Flashes
CHECK THE FOLLOWING:
• Low electrolyte – add de-mineralized water to bring cell levels to maximum.
• Battery is low in charge or fl at – recharge battery immediately.
• Sulphation – FAB is designed to eliminate this problem within a minimum period of 6 weeks.
• Poor connections – Check all wires connected to the battery or batteries are fi rm and clean.
• Battery case distortion – batteries sag over time due to high temperatures in engine bays.
Nothing can be done to rectify this problem.
• Battery plate corrosion - over time battery plates will corrode and batteries will eventually fail
from this cause at the end of their service life.
• Plate material shedding – this is due to road vibration combined with chronic under-charging
causing the plate material to be soft and fall out of the plate grid.
• By Installing FAB charging effi ciency is maximized, therefore reducing plate material shedding
by keeping it fi rm and in place.
What you can do to help slow down Sulphation
• Keep FAB permanently installed on your batteries.
• Refrain from discharging batteries below 50% depth of discharge.
• Recharge batteries as soon as possible after discharge.
1. General information
• Installing FAB is quick, easy and requires no special skills or tools.
• FAB is compatible with all charging systems and is protected against accidental reverse
polarity connection.
• FAB must be installed directly on the battery or battery bank.
• Multiple Units can be installed in series confi guration on large battery banks to achieve
voltages above 48v. For specifi c installation diagrams please email info @megapulse.net
• Each FAB conditions 1500 Ah of capacity, adding more FAB raises the rating by 1500 Ah each
time. For specifi c installation diagrams please email: info@megapulse.net
• FAB will begin to pulse the battery immediately after the commissioning sequence with
the correct amount of pulse energy regardless of the battery test result.
• FAB is water, dust and vibration proof, complying to IP67 waterproof rating.
• FAB is equipped with a 3 second start up delay to eliminate sparking upon connection
to the battery.
• FAB automatically deactivates when the temperature of the internal electronics rises beyond 70c.
• FAB is equipped with a push button 3 Mode Activation Switch to easily switch between modes
to cover most Lead-Acid battery applications.
• Mode 1 (constant) suitable for all applications. Mode 2 (window) suitable for when radio
interference is experienced on AM band, switching to mode 2 deactivates the unit while driving
and re-activates the unit when the engine is off. Mode 3 (high activation) suitable for electric
vehicles if interference is experienced during operation. The factory default setting is mode 1 constant.
• FAB employs an intelligent state of health detection system, automatically adjusting the pulse
output to achieve maximum de-sulphation in the shortest time possible.
• FAB performs an industry standard battery load test (12v, and 24v applications only).
• Load test result displayed as: Green LED = battery Ok / Red LED = check battery.
• FAB performs the load test after installation and repeats the test every 21hr (12v and 24v
applications only) providing the battery is not under charge.
• The on-board battery load test is limited to batteries of 10 Ah capacities and above.
• FAB is supplied with an external 5 amp blade fuse on the positive cable.
COMMISSIONING SEQUENCE UPON INSTALLATION
1. Orange (Mode) LED’s light up to indicate unit start-up.
2. If the battery is below 13v (12v systems) the load test is performed or below 26v for 24v systems.
3. Red or Green LED will fl ash depending on the battery load test result (12v & 24v applications only).
4. Red or Green LED will fl ash depending on the battery state of charge test result(6v, 36v &
48v applications only).
2. Changing the Activation Mode
After FAB has activated, press the Mode Select switch, wait for LED to confi rm activation mode.
