Frequently Asked Questions

What makes the products you carry different from other battery charging and maintenance products available on the market?

PulseTech offers many battery charging and maintenance products that utilize its revolutionary and patented Pulse Technology. This technology is designed to help prevent the main cause of battery problems and failure: sulfation buildup (lead sulfate deposits on the battery plates) and related problems.
Some products may claim to provide the same benefits as PulseTech’s, but most of them merely try to “maintain” the battery by charging them on a constant basis. The problem is too much charging will ultimately overheat and damage the lead plates. In other words, the “cure” could be worse than the disease when not done properly.
Other products even claim to remove lead sulfate deposits from the plates. But this, too, is usually done by over charging the plates with high voltage in order to literally knock the sulfates loose. In this situation, only a few sulfates are removed as active plate material sheds and falls useless away from the battery plates. It’s sort of like blowing up the house just to get rid of the termites.
On the other hand, PulseTech products enable the embedded sulfates to leave the plates and converts them to active electrolyte. They also help prevent sulfates from building up again and won’t harm the battery or the vehicle charging system in any way.

What is a pulse waveform?

PulseTechs Pulse Technology is defined by a distinct “pulse waveform” that has a strictly controlled rise time, pulse width, frequency, and amplitude of current and voltage pulse. It’s the patented combination of the above that makes PulseTech products so different and so effective.

How does Pulse Technology work?

Pulse Technology is a unique, patented process that substantially eliminates sulfation buildup on battery plates, the main cause of lead-acid battery problems and failure. It works by reversing the natural electro-chemical reaction within the battery. In the normal energy transfer process within a lead acid battery, the sulfates in the electrolyte solution (battery acid) travel back and forth between the positive and negative plates, taking on and giving off energy. As lead sulfates form on the plates during the normal charge/discharge cycles, some of the sulfates will root to the plate and enlarge to the point where they will no longer accept or release energy.

Over time these sulfates can build up until battery efficiency is reduced and the battery finally ceases to function. Although there is actually enough reactive material in a battery to keep it working for many years, in most cases it doesn’t because this sulfation buildup prevents the process.

In the past, nothing could effectively be done to stop sulfation buildup and related problems. But Pulse Technology changes all that. This technology is a process that removes excess lead sulfate deposits from the plates and converts them back to active electrolyte.

When used regularly, PulseTech’s battery charging and maintenance systems will also help prevent the lead sulfates from building up again, effectively extending battery service life.

What are the benefits of using Pulse Technology?

The main benefit of Pulse Technology is to ensure battery performance so you can rely on your battery any time you need it. As we said above, by cleaning the battery plates PulseTech’s unique Pulse Technology provides the following benefits:

  • Get better performance by maintaining maximum battery efficiency and reliability
  • Save money on battery costs by extending battery life dramatically
  • Helps batteries charge faster and maintain greater reserve capacity so they can provide more available power to your vehicles and accessories.
  • Help protect the environment by not having to discard batteries prematurely

If Pulse Technology can extend the service life of a battery, how much longer will the battery last?

It’s difficult to determine an exact length of time because service life of a battery varies depending on usage. One independent report stated that Pulse Technology could theoretically “make a battery last forever”, but, obviously that’s a little hard to prove. By using Pulse Technology, though, the life of your batteries will be extended dramatically. Keep in mind that there is actually enough reactive material in a battery to perform the energy transfer process for many, many years, but sulfation buildup has always prevented that from happening. Now, by preventing and even removing sulfation buildup, Xtreme Charge, Solar Pulse and Power Pulse and other products available from PulseTech Products Corporation, Pulse Technology products enable batteries to fulfill their true potential — in performance and life cycle.

PulseTech’s products have been evaluated by NASA, Stennis Space Center, Management Equipment Evaluation Program (U.S. Air Force), the Army Research Lab, battery, auto and boat manufacturers, as well as commercial customers and individuals. The answer from all is the same — “This product does exactly what you say it does!” One evaluating source even stated in their conclusions that “we can’t tell you exactly how long “the application of Pulse Technology” will make a battery last, but we estimate it will add at least eight to ten years of life.”

Will PulseTech products benefit other electrical components on my vehicle?

Yes. By maintaining your batteries in peak condition, your alternator does not have to work as hard at recharging your vehicle once it has started. The battery will accept a charge more readily and faster so alternator life should be extended. Plus, by maintaining available cranking amps in your battery, there will be more available energy going to your starter. The engine will turn over faster, so your starter should last longer as well.

What are other common causes of battery failure that Pulse Technology will help?

It’s interesting to note that other common causes of battery failure (buckled plates, shedding, overcharging, mossing, etc.) are directly related to sulfation buildup. For example, according to a leading battery service manual buckled plates may be caused by “being overcharged while sulfated or stored in a deeply discharged state.” Sulfate buildup weakens the plates to a point where batteries must be overcharged to accept energy. This will then overheat and warp, or “buckle,” the plates. This service manual also relates shedding of the plates to sulfation buildup. It states that “if material has shed from the plates in small chunks, high charging rates on sulfated plates can be the cause.” All in all, each of these and other common causes can be avoided in most cases through the use of PulseTech’s patented Pulse Technology.

Have any scientific studies been done on Pulse Technology?

Yes. Independent scientific studies by researchers at two major universities have confirmed that PulseTech’s patented Pulse Technology does provide exceptional benefits to all types of lead-acid batteries. These studies were conducted in response to a request from the scientific and engineering communities for scientific validation of claims that PulseTech technology actually improves battery efficiency and lengthens battery life. PulseTech contracted with Oakland University in Rochester, Michigan and Ohio State University in Columbus, Ohio to conduct separate evaluations of the technology. These extensive evaluations began in the summer of 1998 and ended in August 2000.

Results of the studies confirmed that several significant improvements in lead-acid battery performance are attributable to Pulse Technology. These improvements are caused by the effect of exclusive and patented Pulse Technology in reducing the buildup of lead sulfate crystals on lead-acid battery plates.

During these studies, these crystalline buildups were regularly investigated by X-ray diffraction methods. The X-ray diffraction data confirmed the positive effects of pulsing on the battery plate morphology because it shows more even distribution of lead sulfate crystals over the surface area of the battery plates.

It also revealed a significant reduction in the size of the lead-sulfate crystals. These microscopic changes greatly improve a battery’s ability to accept and store more energy. Because they store more energy, batteries are lasting longer between recharges, and they are capable of providing more available power than batteries not using the technology.
The effect of the pulsing on the formation of these crystalline structures also increases the battery’s durability. Pulse Technology prevents sulfate-induced corrosion that is the primary cause of shedding of active material. By helping to prevent shedding, the average life span of the battery can be increased dramatically. Tests show that it is possible to get three to five or more times as many cycles from pulsed batteries than non-pulsed batteries. As a result, even batteries on frequently-used vehicles and equipment will receive significant benefits.

Will PulseTech products work on gel cell batteries?

Yes. They work on any size and any voltage lead-acid battery. This includes all conventional flooded lead-acid batteries and sealed “maintenance-free” batteries, including VRLA, absorbed glass mat (AGM) and gel cell battery types.

How quickly will sulfation buildup occur on a brand new battery?

The rate of sulfation buildup on a battery will vary greatly depending on battery state of charge, usage, age and condition. It will occur faster on batteries that are used infrequently but will still affect frequently-used vehicles (see next question).

Also, keep in mind that even brand new batteries may already be sulfated when they are installed on your vehicle. According to a leading service manual in the battery industry, “since sulfation buildup is likely to occur whenever batteries are neglected for long periods of time, it can occur in new batteries that have been in stock for a period of time as well as used ones.”

Sulfation buildup begins to occur the moment electrolyte (acid) is added to a battery. So as new batteries sit in storage or on a store shelf, they, too, can suffer from this buildup. In order to ensure battery performance at all times, it is best if a Pulse Technology product—such as the Xtreme Charge, SolarPulse or PowerPulse is installed or used on your battery the moment it is installed in your vehicle. Or the Pro-12 is put into use on your batteries in storage and/or waiting for sale.

Since sulfate buildup occurs more often with infrequently-used batteries, will I need Pulse Technology even if a vehicle is operated on a frequent basis, like a car or delivery truck?

Absolutely. Even frequently-used batteries charged by the alternator on a consistent basis may suffer from sulfate accumulations. This is especially true for cars, express delivery trucks, buses and other vehicles.
According to a leading service manual in the battery industry, “it is possible for a vehicle to develop an undercharged battery if it is constantly driven at slow speeds and left idling for long periods, as in heavy traffic and combined with high electrical load conditions.” If a vehicle is moving at slower speeds, idling a lot or suffering from an overtaxed electrical system the alternator is not allowed to charge at an optimum rate. The result is a battery that is not fully charged even though the vehicle is running all day. And since it isn’t fully charged, it will begin to sulfate. A vicious circle is then created because the more the battery sulfates the less energy it will accept and the battery will be undercharged even more. Ultimately, it too will become sulfated and fail to provide energy.
By keeping the battery plates clean with Pulse Technology, the battery capacity is increased so it will accept and store energy more efficiently which will help eliminate the problem of undercharging.

Is it true that charging batteries in reverse polarity will desulfate the plates and prepare it for a better recharge?

Absolutely not. This will actually damage your battery and could even lead to an explosion. Attempting to charge a battery in a reverse polarity should NEVER be performed for any reason.
For safe, effective prevention and removal of sulfation buildup on battery plates, use only our Pulse Technology products.

Will weather affect my battery?

Yes. What many people don’t realize is that extreme cases of heat and cold will increase the speed of sulfation buildup and the rate of discharge within a battery. For example, when the weather starts to get hotter, the rate of sulfation buildup will actually double for every 10-degree increase in temperature. That means that if the temperature goes from 75° to 95°, sulfation buildup on battery plates will occur 400% faster than normal. So….batteries stored or in vehicles in warm weather have the potential to fail due to the build up of sulfation, much sooner than batteries stored or in vehicles in cooler weather.

Cold weather, this is a real “Domino Effect” …When it’s cold outside, sulfation buildup in combination with the slow down of the chemical reaction within the battery will rob the batteries ability to provide operational power and is only exaggerated as vehicle fluids thicken due to the cold. This cold condition causes even more available power and capability to be taken from the battery to start the vehicle, so the battery has to work harder than normal to provide additional power demanded by the vehicle and as a result realizes a further reduction in voltage causing faster buildup of sulfates on the lead plates. Also, keep in mind that the battery’s electrolyte can actually freeze if the battery is in an advanced state of discharge, and this could physically damage the lead plates. At 1.270 specific gravity (100% charged) battery acid will freeze at -83°F, at 1.200 it will freeze at -17°F and at 1.140 (completely discharged) it will freeze at only 8°F.

Will PulseTech products damage electrical systems on cars and other vehicles?

It is not possible for any of PulseTech’s products to damage the electrical system on any vehicle. By attaching the product to the battery, the pulsing energy is absorbed within the battery and is not “seen” elsewhere in the system. This technology has been applied to a variety of military vehicles with very sensitive launching systems or computer systems with no interference or problems.

PulseTech products have also been evaluated by a major auto manufacturer and has passed all the emissions tests they put the products through. Their products can only enhance a vehicle electrical system—not detract.

Can these products overcome a battery’s internal resistance?

The internal resistance within a battery is a function of the electro-chemical reaction that is taking place. You would not want to interfere with this as it is part of the energy transfer process. However, you would want to offset the negative impact of this process which is exactly what PulseTech’s patented Pulse Technology accomplishes.
By using this patented Pulse Technology to desulfate a battery on a daily basis, the battery will perform better, last longer, be more dependable and have more available energy for your use.

Will they hold up on day-to-day usage?

Absolutely! One of the reasons PulseTech first took this revolutionary technology to the U.S. Military many years ago was to verify the durability of the product. Because of the patented design and proprietary manufacturing process, their products are as durable, if not more so, than the piece of equipment you are mounting them on! This exceptional durability is also why PulseTech gave Xtreme Charge, SolarPulse and PowerPulse a 5-year limited product warranty!

Does the Xtreme Charge models have to stay on the same battery permanently or can you move them from battery to battery?

These units can be moved from battery to battery if you chooses to do so, but we strongly suggest you install them and use them on a regular basis. Remember that sulfation buildup happens 24-hours a day from the first moment the battery is “born” or acid is loaded into the battery. Although you can use Pulse Technology as a part-time fix, a continuous installation will give a much more effective result because not only do they eliminate the existing buildup, they also prevent the lead sulfates from building up again.

Can they be used on more than one battery at a time?

It depends on the model. The standard Xtreme Charge (XC100) is designed for use on 12 Volt systems (2-6V batteries in series connection or one 12V battery only). The XC100 PARALLEL is designed for use on two 12V batteries connected in parallel.

Do any PulseTech products work on 6-volt lead-acid batteries?

Yes. Although all of their products are designed for 12 volt systems application of Pulse Technology on 6 volt batteries can be achieved through series connection of 6 volt batteries creating a 12, 24, 36 or 48 volt system. Product use is dependent on final overall system voltage

Which product should I use when storing my vehicles for long periods of time?

We suggest you use the Xtreme Charge if stored indoors with access to AC power or SolarPulse SP2 or SP5 if stored outdoors without access to AC power but access to the Sun’s energy. Besides preventing sulfation buildup, they also prevent the normal loss of battery power no matter how long your vehicle or equipment sits unused—even months at a time.

For example, under normal conditions a battery will lose 1% of its energy a day while the vehicle sits unused. That means it will not take long for a battery to become completely discharged, especially if it was not fully charged in the first place. Xtreme Charge and Solar Pulse will not allow those batteries to loose energy and will maintain them indefinitely. The Solar Pulse will maintain and condition the battery and the Xtreme Charge will Charge, Maintain and Condition the battery every day.

If you do not have access to ac power or sunlight, you can use PowerPulse. Keep in mind that PowerPulse was designed more for vehicles and equipment that are used frequently or charged on a regular basis vs. those that are stored. Yet, based on lab testing, a 12-Volt PowerPulse will maintain a 12-volt battery for approximately 2 to 3 months off a full charge if left unattended. We’re not saying the vehicle will always start at that point, but the battery will be free of sulfation buildup, will be able to be jump-started into action, and it will recharge and hold a charge like a new battery.

Is it possible to recover a dead battery that will no longer accept a charge?

Yes, if you are using a PulseTech product. Although their products are designed for keeping good, new batteries in peak condition for a longer period of time, some of them can, in most cases, be used to bring batteries that will not accept and hold a charge back to useful condition.

Here’s what you do: Use a PulseTech 390PT (741X390) Digital Battery Analyzer to determine if the battery is a good candidate for recovery (Note: Even though the analyzer may read “REPLACE BATTERY,” it could still be recoverable.)

The ideal way to recover a battery is to use the Xtreme Charge 20A Pulse Recovery / Maintenance Charger. Make sure the cells are filled with distilled water and attach the battery to the Pulse Charger. If the Bad Battery light begins to flash, it is indicating a problem and the battery is probably not recoverable. If the light does not flash, you can proceed.

Leave the Charger on the battery for at least 36 hours. At any given point during the charge is may shut off automatically so it won’t overcharge your battery. During the “off” period it is no longer charging but you will notice that it will continue to pulse condition the battery. As it continues to pulse and de-sulfate the battery it is likely to cycle through the charge and pulse sequence a number of times before the battery is brought back up to an improved condition. The number if times it may cycle will be dependent upon a number of factors including the age of the battery and the time it may have been sitting unused, the depth of discharge, the physical size of the battery (amount of plate surface area) and the depth or state of sulfation damage that may have occurred.

Next, use the PulseTech PT390 digital battery analyzer as mentioned above to check the battery for improvement. If there has been at least a 20% increase in Cold Cranking Amps (CCA), you may proceed repeating the process as needed using the analyzer to check for improvement.

Keep in mind that some very badly sulfated battery plates could take several days to clean. Also, not all batteries can be totally recovered. If a battery has a short circuit or physical damage, it is impossible to bring back.
