The PulseTech PowerPulse PP-12-L is not a charger. This on-board device utilizes revolutionary ReNew-IT Pulse Technology to safely prevent the main cause of battery problems and failure: sulfation.

Over time, the chemical reaction of lead acid batteries, force sulfates to leave their liquid state, adhere to and build up on the lead battery plates. This build-up of sulfur crystals inhibits the electrolyte from reacting with the plates and slowly kills your battery. The phrase, "my battery never seems to have the power it used to!" is a common remark, that does not need to be uttered when you use a Power Pulse onboard desulfator. The PP12L will prevent sulfation from occurring and can even reverse the effects and recondition batteries that have become sulfated.

Selected as a Top 50 Product by Automotive Engineering magazine, the 12-Volt PowerPulse is designed to ensure maximum battery performance on single 12-volt lead-acid batteries. It also works on two or three 12-volt batteries connected in parallel. The PP-12-L is ideal for virtually any kind of vehicle or equipment that is charged on a regular basis, including cars, over-the-road trucks, delivery trucks, boats, emergency vehicles, generators and much more. It comes with 3/8 lugs that connect directly to the battery terminals.

Why waste time and money replacing batteries prior to their expected life span? Start using the PP12L PowerPulse on-board desulfator today to extend the life of your new lead acid batteries up to 2-3x. With the cost of lead continually rising, It is worth the investment!

FAQs About This Product

Ask a Question

  • 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.

    Rate This Answer:

  • Can this desulfator handle (4) 100AH batteries in parallel (12V system)?
    Yes, but you may want to install 2 on a system of that size. Generally, I don't like to exceed one for every 200-300ah.
    Rate This Answer:

  • I have a 36-volt golf cart (6 ea 6-volt batteries wired in series). What power pulse unit should I be looking at buying?

    You could use 3 of the PP-12-L but it would be easier to use the PP-36-L which is specific for 36V carts.

    Rate This Answer:

  • I have dual batteries on my super duty diesel just wanted to see if I would need one for each battery. Don't want to buy 2 per truck if I don't need to...
    If your batteries are near each other then one desulfator can reach across. However if they are on opposite side of the vehicle one unit will not extend that far.
    Rate This Answer:

  • Does this unit desulfate only while the battery is energized by a working alternator or does it continue to work while the engine is at rest?
    It will work during a charge sequence and after charge is complete. If the vehicle is left sitting for a long period of time, the Power Pulse will stop working when the voltage hits 10.5V
    Rate This Answer:

  • Can Power pulse be hooked directly into the operating system of a car to protect the Battery while traveling?
    It is best to have the Power Pulse connected directly to the battery terminals.
    Rate This Answer:

  • I have 4- 6V batteries wired in series for my RV. What do you recommend? I am also interested in a solar charger for trickle charging the same. Recommendations?
    I will assume your question is in regards to desulfating batteries and will assume you are set up to run 12V in your RV. I think we can kill two birds with one stone and would benefit from using the SP-5 solar charger by Pulsetech.
    Rate This Answer:

  • Is this required if using all AGM batteries?
    This is not a requirement, but is a good idea to use on any lead acid based battery. Yes AGM and Gel are considered lead acid based.
    Rate This Answer:

  • Will this work with agm batteries,and will one work with 3 4d marine batteries connected in parallel?
    Yes these work on all types of lead acid based batteries including WET, AGM and GEL. When working with larger batteries such as the 8D and 4D I prefer to use one desulfator per battery.

  • Hello,I have 4 12 volt batteries in parallel. Do you offer a desulfator for this?ThxEric
    You can use any of the 12V onboard desulfators. Depending on the size of your batteries you could use two evenly spaced on your batteries.
