Review Everything You Need to Know About Battery Sulphation, Desulfation, Desulfators & Rejuvenation

  • Why should I care about sulfation?
    Battery sulfation is a wasting disease that claims the life of up to 80% lead acid batteries in use worldwide. There is actually enough reactive material still in these batteries to keep them working for many years, however, the sulfate buildup eventually prevents the batteries from performing efficiently or being able to adequately hold a charge.

  • How does Pulse Technology help?
    Pulse Technology has been PROVEN to remove naturally occurring lead sulfates from the battery plates and returns them to the electrolyte solution. Used consistently, Pulse Technology prevents the larger sulfate crystals from forming allowing more room in the battery to store energy which in turn allows the battery to operate at maximum capacity.

  • How do you prevent Sulfation?

    The simplest answer in helping to prevent sulfation is to keep your batteries attached to a smart charger--thus keeping them fully charged when not in use.

    We wrote an article relating to this topic that presented some questions and evidence regarding the impact of desulfators in preventing and removing sulfate buildup. It is found in our November issue of Pulse Talk linked here.

  • What is the difference between desulfation and desulphation?
    The short answer... nothing. It is simply the difference between British English and American English. Both spellings or the derivatives of both (i.e. desulfation, desulphating, desulfated, desulphated) are even used interchangeably on the same publications.

  • Will My Desulfanator Charge My Battery?

    Yes and No.

    Generally speaking the on-board desulfanators (properly pronounced desulfators) will not charge your battery. In fact many will use your batteries power to run through its pulse phases. This will actually run down your batteries voltage to the point of being drained if the desulfator has no built in auto shutoff. Some only operate when they detect current from your battery charger and work in conjunction with the charger.

    The battery charger desulfators are a smart charger and a desulfator built into one unit. And yes these will charge or maintain your battery at full charge.

  • So what exactly is a Battery Management Program (BMP)?

    The Battery Management Program or BMP for short is a system developed by PulseTech to test, recover, charge, and maintain lead acid based batteries. The environmental, physical and financial benefits gained are nearly immediate and are ongoing.


    Recover & Charge

    • Use the XC100-P, XCR-20, SC-6, SC-12 Patented High Frequency Pulse
    • Recover Any Type Lead Acid Battery: Wet, Gel, AGM
    • Over 70% Of 'Dead' Batteries Can Be Restored


    • High Frequency Low Profile Solar Pulse Desulfators (i.e. SP-2, SP-5)
    • 12V, 24V, 36V, 48V Onboard Power Pulse High Frequency Desulfators
    • Multiple Storage Batteries RediPulse 12 Bank Pro12 Desulfator
    • Keeps Batteries In Peak Operating Condition Longer

  • What is a Desulfator?

    A desulfator is a device that when attached to a lead acid battery will clean the internal plates. They remove hardened sulfate crystals that have built up as a result of sulfation (see: What is Sulfation?). True desulfators use a pulse frequency to desolve these crystals vs. the less effective voltage pulse

  • Battery Desulfators - Do They Work?

    Yes, battery desulfators work. Those who say otherwise either have not tested one and or work for a battery company and don't want to diminish sales. To read more on this subject read this blog post.

  • What Is Sulfation?

    Sulfation is the buildup of lead sulfate (PbSo4) crystals on your battery plates.

    Contrast image of built up of sulfate crystals on a battery.All lead acid batteries will suffer from the effects of sulfation. It is the unwanted byproduct of the natural double sulfate chemical reaction that generates electricity within the battery. When a battery is in use, the active material on your battery’s plates, lead and lead dioxide, react with the electrolyte or sulfuric acid (H2SO4) to generate electricity. During this process a thin layer of non-crystalline solid lead sulfate is deposited on the plates.

    During charging, this sulfate deposit is supposed to be converted back to lead dioxide and sulfuric acid restoring the battery back to its pre-discharged state. However, the process is not perfect. Incomplete charging or prolonged time left in a discharged state will convert the amorphous (non-crystalline) lead sulfate into a hardened crystalized form diminishing the ability of the battery to reach full charge.

  • I live off the grid and have 32 deep cycle batteries charged by solar panels, seasonal hydro and a generator. My system is 48V with Magnum inverters. Do you have anything like the XC100-P that would work to increase battery life?

    48 volt Series DiagramIt sounds like you want to prevent / remove the debilitating effects of sulfate in your batteries and would be best served with an on-board desulfator.

    The size of your battery bank may be best served by using 1 of 2 methods. A 36-48V High Powered Industrial Desulfator (BLS-36/48-Multi-F) made by Battery Life Saver or by breaking your system down into multiple sub-series and use the 12V or 24V units.

    Example a 48V system utilizing four 12 volt batteries could use four 12V Power Pulses or two 24V Power Pulses or one 48V unit.

  • My battery is already a couple of years old. Is it too late for Pulse Technology to work?
    No it’s not too late. In fact, desulfators can return your battery to a like new condition and will feel like you have full capacity again. In addition, when used on new batteries, they can extend battery life up to 5 times.
