PowerPulse: What Is It And Do They Work? PulseTalk October 2026

In this month’s edition of PulseTalk, we will be exploring the PowerPulse onboard desulfators and how they should be used within a Battery Maintenance System (BMS). These tiny, yet powerful, devices help ensure peak battery performance and can extend battery life up to three times using patented pulse technology.

PowerPulse is a battery maintenance technology designed to help reduce sulfation in lead-acid batteries. It sends high-frequency electronic pulses through the battery, which can help break down sulfate crystals and improve battery performance and lifespan.

Sulfation is one of the most common causes of battery failure. When a battery remains partially discharged for extended periods, sulfate crystals can build up on the battery plates, reducing its ability to hold a charge. PowerPulse technology aims to minimize this buildup and keep the battery operating more efficiently.

Many vehicle owners, RV users, and equipment operators use PowerPulse devices to maintain batteries during storage or regular use. While it cannot repair severely damaged batteries, it may help extend battery life, improve charging efficiency, and support more reliable starting performance when used as part of a proper battery maintenance routine.

So, How Does the PowerPulse Work?

PowerPulse works by sending high-frequency electronic pulses through a lead-acid battery. These pulses help reduce sulfate crystal buildup on the battery plates, improving charge acceptance, maintaining performance, and potentially extending battery life by minimizing one of the primary causes of battery degradation.

The PowerPulse uses a patented pulse technology that reduces and prevents sulfation buildup on lead acid based batteries. The ongoing process allows the batteries to be completely charged and to give off a complete discharge. This constant equalization effect reduces internal resistance in the batteries, leaving them in like new condition.

You will save many man-hours needlessly replacing ‘spent’ batteries and will obviously not have to spend your hard earned cash buying new batteries as often. For batteries used in starting vehicles there is an added benefit; lower internal resistance means there will be less wear and tear on your starter and alternator.

How Do You Deploy the Power Pulse?

The PowerPulse onboard desulfators come in four standard voltages: 12V, 24V, 36V and 48V. They can be used with any lead acid based battery system including VRLA, Gel, Flooded and AGM batteries. You would then create an individual or series connection matching the above voltages. Ideally, you would want to deploy the PowerPulse on a battery system that is charged regularly as they utilize less than 2% of the battery’s own energy to operate. Over time, if the system is not regularly charged, the batteries will become discharged. This energy usage would be akin to a parasitic drain.

We like to use these onboard desulfators more in a preventative scenario vs. a restorative rejuvenating scenario. How does the saying go? An ounce of prevention is worth a pound of cure. It seems far easier and less costly to prevent sulfation before it starts. Can they be used in both situations, most definitely yes, but we feel Pulse Tech has created better tools, mainly desulfating chargers, to more efficiently deal with the debilitating effects of sulfation. It could take the PowerPulse 2-10 weeks to reverse the effects of a heavily sulfated deep cycle battery while a desulfating charger could complete the task in 24-72 hours. In short, proper charging algorithms coupled with patented pulse technology are essential and time is money.
