INFINITUM STORE: How Do Desulfators Work?

How Infinitum Desulfators work

As most batteries are idle longer than they're charged, the batteries are left discharging for longer periods of time than when they are charged.

Charging: 2PbSO4 + 2H20 → Pb + PbO2 + 2H2SO4

Discharging: Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H20

This causes water and lead sulfate (PbSO4) to form at a faster rate than it can be reconverted back to lead, lead dioxide and water. Lead sulfate that's left sitting, originally spongy, will eventually crystallize. Once in crystal form, the lead sulfated cannot be reconverted, even when the battery is being charged. This causes a reduction in active material (the lead and lead dioxide) and surface area where chemical reaction takes place. Eventually, the battery will no longer have the capability to supply enough cranking current to start a car. This process, also known as sulfation, is the main cause why batteries fail prematurely!

The Infinitum Desulfator generates Amplitude Modulated Pulses (AMP) at the resonance frequency of the crystals to shatter the covalent bonds that hold it together. This allows the lead sulfate to be reconverted once the battery is charged. A battery free from lead sulfate crystals will have its life span stretched to its maximum! No more premature failure due to sulfation!

Lead sulfate crystallization causes more than 3/4 of batteries to die before their designed life span!

How your batteries die due to sulfation

Spongy Sulfation

Stage 1: Spongy Sulfation

The lead sulfate is still in its spongy form. In this form, the lead sulfate and water in the battery is converted back to lead, lead dioxide and water when the battery is charged. The internal impedance of the battery is very low (usually < 6 mΩ).

Barrier Sulfation

Stage 2: Barrier Sulfation

Covalent bonds form and small crystals start to appear on lead plates. The internal impedance of the battery would be higher than that of a battery with spongy sulfation. The battery may not be able to crank a car.

Crystallized Sulfation

Stage 3: Crystallized Sulfation

Large crystals with very strong bonds have formed on the lead plates. There is very little surface area on the plates where chemical reactions can take place. The internal impedance of the battery is very high. The battery cannot crank a car.

Battery Status Display

Green LED - Battery voltage is above 12.5V. The Green LED must be on when the engine is running. Red LED - Battery voltage is below 12V. You should never see this when the engine is running! If your engine is running and no LEDs are illuminated, either the unit has failed (which is unlikely) or your alternator has failed. When you crank the car, you may notice the Red LED illuminated for a short while, then the Green LED lights up. This is normal. During cranking, current is drawn out of the battery, causing a drop in voltage. At this moment, the Red LED indicates the voltage drop. After the alternator kicks in, the Green LED will illuminate, confirming that the voltage is above 12.5V.

Test results in reviving a 'dead' battery

Charging characteristics of a 'dead' battery 17Ah, 12V Sealed Lead Acid Battery

A randomly chosen sealed lead acid battery of 17 Ah, 12V that was abandoned for 6 months was selected for this test.
The initial battery voltage measured was 6.0V and attempts to recharge it failed as it will not take charging current. The maximum charging current achieved was 0.2 A – 0.3 A.
The same battery was fitted with the Infinitum Desulfator and charged for 10 hours and results were recorded as above.
The results clearly showed a successful revival of a dead battery.
