Batteries often fail because “sulfates” slowly develop and cover the battery plates. This sulfating process also weakens the electrolyte and this combined with the gradual coating of the plates slowly and almost imperceptibly reduces the battery’s ability to receive, store and then deliver power. This sulfating process gradually impairs battery function and causes a capacity loss until the battery can no longer perform the desired task and so the battery is deemed to have “failed”. However using an Auto Pulse Battery Desulfator can reverse the process by dissolving the sulfates, cleaning the plates and restoring the electrolyte strength so improving a battery’s life and capacity for an extended period.


The High-frequency Peak Pulse delivers an electronically controlled pulse to the battery causing crystalline sulfates to dissolve back into the electrolyte and so restoring battery function and electrolyte strength regaining the batteries ability to receive charging current and deliver discharge current.


• Automotive batteries • Motorbike batteries • Marine, jetski batteries • Truck, RV batteries • Electric golf carts • Electric cars and scooters • Electric bicycles • Electric wheelchairs • Earthship / off-grid battery banks • UPS battery banks • DC systems of electrical substations • Telecommunication hubs • Wind farm storage systems • Solar farm storage systems • Back-up system battery banks • DC starting systems of generators

Many desulfator products use an old technology inductor design to generate the pulse to desulfate a battery. This old technology creates a harsh inductor peak that can be damaging to the battery plates.

Utilising our new capacity pulsing method a “soft” peak is generated so dissolving sulfates without damaging the battery plates.
Old technology also requires a large inductor so necessitating a physically large desulfator device whereas using our advanced technology design the Auto Pulse Desulfator device is very compact yet provides BIG performance.

In a similar manner to a Pulse battery charger (charge – rest –charge – rest etc) a cyclic desulfating pulse function (pulse – rest – pulse – rest etc) optimizes a batteries recovery process. This method of desulfation has been implemented in the new Auto Pulse Desulfator

Increases Battery Power
Extends Battery Life
Battery Charge Faster
Longer Discharge
Prevents Sulfate Build-up
Reduces Evaporation


Fully Automatic voltage selection. 12V 24V 36V and 48V
New Cyclic pulse generation method for improved capacity recovery
Soft” Peak Pulsing
Auto cutoff function to prevent over discharge of battery
User Configurable override for manual voltage selection


Just Red terminal connect to battery positive and black terminal to battery negative. And Auto Pulse Battery Desulfator can cutoff when battery’s voltage is low.


If the battery voltage is very low the automatic voltage selection may fail to set the correct voltage. In this instance it is possible to manually set the desired operating voltage. By pressing the voltage select button. The LED screen will first display the working voltage and if you want to then alter the working voltage setting just presses the key again and the unit will change to next value. After setting the desired voltage the display will switch off to conserve battery power.
