Yes. We offer several types of chargers including the XC100 Xtreme Charge, the X2 dual station Xtreme Charge and the SC-12 Pulse Charger – 12-station charger.

The Xtreme Charge single and dual station units are state-of-the-art "smart" charging systems that are actually four chargers in one. It's a state-of-the-art charging system (up to 2.5 amps) that works with all 12-volt lead-acid battery types including conventional flooded lead-acid batteries and sealed "maintenance-free" batteries, including VRLA, AGM and gel cell batteries. They also works off either 110- or 220-volt ac power so it can be used virtually anywhere in the world. At the same time, the Xtreme Charge uses our unique and patented Pulse Technology to remove sulfation buildup. Use either of these Pulse Chargers to return unreliable 12-Volt lead-acid batteries to active service.

The SC-12 is a multiple (12 station) 6A battery charger. It is a portable charger that can solve your battery problems much more quickly – times 12! It not only charges 12 batteries at a time but will maintain and condition them as well. It's ideal for all service facilities that deal with multiple vehicles with multiple batteries.

Yes, if you are using our Pulse Technology products. Although our products are designed for keeping good, new batteries in peak condition for a longer period of time, some of them can 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 our 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 it 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 of 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.

Yes. The Xtreme Charge range of chargers are AC powered.

PulseTech offers many battery charging and maintenance products that utilize our 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 ours, 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 electrolytes. They also help prevent sulfates from building up again and won't harm the battery or the vehicle charging system in any way.

It depends on the model. The standard Xtreme Charge (XC100-P) is designed for use on 12-Volt systems (2-6V batteries in series connection or one 12V battery only) unless it's connected to the QuadLink and can then maintain up to 4 12-Volt batteries.

The XC100 PARALLEL is designed for use on two 12V batteries connected in parallel. The SolarPulse (SP-2 and SP-5) are designed for use on 12V batteries.

The PowerPulse 24, 36 and 48-volt systems can work on batteries in parallel or individual batteries that are "voltage specific" which means they are designed to work only with their designated voltages: A 24-Volt PowerPulse on a 24-volt battery system only, and so on. They can also work on batteries in series: A 12-Volt PowerPulse can be used to charge 2 6-Volt batteries in series.

The 2-Station Xtreme Charge (X2) is designed for use on two 12-Volt batteries or a 24-Volt battery system. Two QuadLinks can also be connected allowing the charge of up to 8 12-Volt batteries or up to FOUR 24V commercial systems composed of two 12V batteries connected in series

The Pro-12-RP is designed to maintain up to 12 batteries at a time when in storage and/or waiting on a store shelf for sale.

The QuadLink is designed to maintain as many as four 6 or 12-Volt batteries depending on the capabilities of the battery charger.

We suggest you use the Xtreme Charge (XC100) if stored indoors with access to AC power or SolarPulse SP-2 or SP-5 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.

If you need to keep multiple batteries maintained then one of our QuadLink Kits is ideal. It comes with an Xtreme Charger and one or two QuadLink Multipliers (depending on which kit you decide on – either the XC-QL4-K1 or X2-QL4-K2) and will maintain either 4 or 8 batteries in peak condition.

Keep in mind that 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.

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.

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 our patented Pulse Technology.

Yes. They work on any size 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.

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.

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.

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.

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.

It is not possible for any of our 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.

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

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 our patented design and proprietary manufacturing process, our products are as durable, if not more so, than the piece of equipment you are mounting them on! This exceptional durability is also why we gave Xtreme Charge, SolarPulse and PowerPulse a 5-year limited product warranty!

These units can be moved from battery to battery if the customer 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.

Yes. Although all of our 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.

Our SolarPulse range of products produce a charge for voltage maintenance when the battery's voltage falls below a predetermined point along with the desulfation process via a separate circuit. It provides enough power to offset the normal daily discharge of a battery (usually 3.1mA to 10.1mA depending on the battery chemistry) plus a nominal amount of parasitic drain. This was recently verified independently by one of the major U.S. auto manufacturers. Keep in mind, though, that while they do supply a charge and pulsing to the battery, the charge rate is not sufficient to charge a completely dead battery in a short time frame.

PowerPulse is a battery maintenance system designed to prevent sulfation buildup only. It will not charge.

Use of these Pulse Technology products will enable chargers to do their work more efficiently. Since they help keep the battery plates free of sulfate deposits, it takes less time to charge the battery and battery capacity is increased so it has greater discharge capabilities and it will last longer between charges.

While we cannot tell you all the details as this is part of our patented process; we can tell you this much...The Xtreme Charge shows 25%, 50% or 75% based on a composite result comprised of multiple readings over time gathered and reported on by its microprocessor. These factors gathered by our patented algorithms and compiled and reported on by the Xtreme Charges microprocessor determines a reading of 25%, 50% or 75% charged. The 100% reading is shown based on a composite result gained from amperage acceptance over a given time period under charge and the level it has dropped down to over another period of time. As one technical editor stated in an article about our products – "The Xtreme Charge brings Dad's old buzzing box of diodes into the computer age!"

Yes, clipping two sets of leads (one of each from two separate channels) on the SC-12 to a battery will safely double the amperage going to a given battery allowing a faster charge which is especially useful when charging a larger battery. Always top the battery off for a few hours with one channel (one set of leads) after bulk charge is complete.

• 25% - 9.8 to 12.0V
• 50% - 12.0V to 12.4V
• 75% - 12.4V – 12.6V
• 100% 12.6 – 13.8V

Note: for battery state of charge indications the Quick Battery tester is a very basic open circuit voltage meter designed to help determine when a battery should be recharged. It is not intended to be used for in depth diagnostics.

Good – 13.8V to 14.7V, Bad – 14.7V - up

Note: the Quick Battery tester is only a basic open circuit voltage meter designed to help determine if there may be a fault in the charging system – the "Bad" indicator light only lights as a result of a High voltage limit of 14.7V or higher – there is no low voltage indicator for a "Bad" reading.
