Sulfation can mean the eventual death of a car's battery which could mean the death of an engine at the most inopportune moments.

If you consider a car's powerplant to be its heart, then the electrical system would be its central nervous system. Like any central nervous system, the car's electrical system controls nearly every aspect of a car's operation. From the engine firing sequence and climate control system to the car's electronic safety system, they're all heavily dependent on the reliable operation of the car's electrical system.

As modern cars grow more sophisticated with even more electronics than before, the stability and reliability of a car's electrical systems gains even more importance.


Any voltage fluctuations would mean detrimental errors might occur in any of the systems mentioned above. In the worst case scenario, if the safety systems were to malfunction, it might even result in an accident. Sensors in the Electronic Stability Program and Auto Braking System might get inaccurate readings from electrical interruptions which might cause abnormal reactions from these systems.

Importance of your car's battery

The battery plays a big part in a car's electrical system as it is also laid with one of the most important tasks in a car. The task being getting the engine started when needed.

The battery is integral in keeping the vehicle's auxiliary systems functional even when the engine is off. Examples include the clock, radio and windows. A major component that the battery supports is the starter motor which is used to fire up the engine.

A car's battery is regularly charged when the engine is running while the alternator powers the car's electrical system and restores the battery's electrical energy.


When the battery's ability to hold a charge is compromised, one would find it difficult to start the engine. This would bring about the hassle of getting the vehicle hooked up to another with jumper cables in an attempt to breathe life into the engine once more.

What is battery sulfation?

A normal car acid battery consists of a series of oppositely charged lead and lead oxide plates that divide into cells within the battery. The battery cells are filled with a mixture of 65% distilled water and 35% sulphuric acid or electrolyte solution. Electrolytes produce electrons and while under charge, the electrons move between the plates discharging energy in the form of volts. The lead plates convert this energy into electricity. Each cell can produce about 2.1 volts of charge which means a 12.6 volt battery requires six cells.

Battery sulfation impedes a battery's ability to accept, hold and deliver a charge. If left unchecked, sulfation would disable a battery's usability way before its designed service life. This would be a costly preposition considering a car's battery can cost anything from $100 to $200. If properly guarded against sulfation though, a battery's service life can be extended for years beyond its designed service life.

When a battery is left unused for a long time, sulfation occurs as the electrolyte solution begins to break down. Sulphur in the solution separates from the electrolyte and attaches to the lead plates and eventually gets converted into lead sulphuric crystals.

The crystals coat the plate and prevent them from conducting effectively. This means the battery will be unable to provide enough electricity to the ignition coils to turn the engine over. The situation is made worse now that the electrolyte solution is weaker because the sulphuric acid has turned into crystals and now delivers much less charge.
The weakened battery with its limited storage capacity and ability to give and receive charge adversely affects the battery's State of Charge (SOC). State of Charge refers to the amount of electrical energy left in a battery. For example, the battery indicator on your handphone reflects the battery's SOC which is usually represented in percentages from 0 - 100% with the battery's maximum SOC being 100%.

To prevent sulfation, a battery needs to be kept in a fully charged state. Though disconnecting the battery might slow the rate of sulfation, sulfation and natural discharge will still occur.

What is the solution?

There are however devices on the market that will help to prevent sulfation occurring on your car battery. Max~Zone is one such device that employs a state of the art Pulse Technology.

Pulse desulfation technology uses pulses of electrical energy that are tuned to the molecular frequency of the sulphur crystal. The pulsing will break the bonds of the crystals and dissolve it back into the electrolyte solution, saving the weak battery from having to be replaced.

Such devices like Max~Zone come with bolt-on simplicity. The small electronic box is hooked up next to a car's battery and sends out high frequency pulses to the battery through its Intelligent Fuzzy Pulser to counteract the battery's sulfation rate.


Max~Zone, with its intelligent Fuzzy Pulser technology, will be able to disulphate a sulphated battery with only a 50% maximum SOC to regain up to 80% maximum SOC. The battery will be able to maintain its 80% maximum SOC throughout its service life. The Max~Zone product though is more than just a desulfator as it also improves ignition as well with its multi-spark technology that sends multiple pulses within a single pulse in an engine that isn't equipped with it. This results in less misfires which in turn leads to better combustion within the engine.

Improved combustion also means less carbon build up within the engine. The 25,000 volt plasmatic ignition from the Max~Zone device dissolves carbon deposits and are expelled through the exhausts. This results in a cleaner combustion chamber, pistons, spark plugs and valves which results in less wear and tear on these engine components.


Further enhancing the combustion process is the ionizing feature that applies a magnetic field to the fuel. This process changes the polarities of the fuel and thus allows the hydrocarbons in the fuel to react more spontaneously and burn more efficiently.

The device also acts as a voltage regulator to ensure that power levels throughout your car's electrical system is stabilised. This ensures there's no electrical fluctuation within the car's systems and prevents a malfunction.

Once your car's electrical system is stabilised, the Max~Zone device presents other improvements that stem from a stable and reliable current in your electrical system. You get smoother acceleration, gear changes in an automatic gearbox becomes smoother, air-conditioner works with improved efficiency and the audio system becomes louder and clearer.

With the installation of a product like Max~Zone, you can ensure that your car's electrical system and most importantly, the battery will be well maintained and be able to serve out its designed service life and beyond with minimum reduction in its performance.
