The BATTERY SMACKER is a Battery De-sulfator,
Battery Rejuvenator & Battery Re-charger all in one.
Works best on flooded lead acid batteries.

A customer asked about Smacking AGM batteries - (Absorbed Glass Mat batteries) AGM Batteries have very little water, in the form of  concentrated sulfuric acid soaked fiberglass mats sandwiched between the plates. There will be less of a charging response, but... Put enough of those AGMs in parallel, it'll add up to enough water to absorb all of the energy that is entrained. A simple explanation of the flooded batteries vs AGM batteries can be found here. (9/19/18)

Bob Boyce the Battery Smacker Inventor writes :

I developed the Battery Smacker technology in the 80s, it just was not brought out as a product for market until more recent years. I use a much larger Battery Smacker type system (Toridal Power System) on my own battery banks, ones that are designed for the specific batteries used, and the voltages of the battery banks. I have 4 separate solar power systems in use here for the house, shop, and outbuildings. The newest one delivers 7 times the power of the solar array source, to the battery bank.

I have decades of experience with solar power systems. In the 80s, I had a lot of experience with AGM batteries, as we had to replace them yearly in the governmental backup power systems. I was given all of the 12V 100 A/H batteries that were removed, so I used them myself. It is the experience that I gathered from those years, that initially caused me to become biased against AGM for renewable energy systems. The government would rather replace them yearly, than to deal with relying on people to maintain flooded lead/acid systems. I found that even with the charging profiles tailored precisely to the battery manufacturers specifications, the best battery life we ever had was 3 to 4 years from the AGM batteries.

At that time, Johnson Controls was the preferred vendor of the batteries for the government. I used my earlier version of the Battery Smacker on my own battery banks of these. After migrating to flooded cells after my retirement from the Pentagon, I found that identical capacity flooded cells, properly maintained, would last a minimum of 7 years, without a Battery Smacker. I've helped redesign several solar power systems for neighbors since moving here in 1997. I did not sell those systems, they were designed, sold, and delivered by solar energy companies. One of these had been installed in 2008 to supply power for a pair of 2012 underground bunkers for a doctor. In 2010, he asked around for someone to help him, both of his systems were not working. The contractor had installed 2 huge AGM battery banks, and both had failed before the doctor could move in. I was referred, went out to inspect the systems, the AGM batteries had dried out. I had the doctor order new batteries, and he ordered the same exact kind from a solar outlet in Arizona. They were delivered by truck, and he had a contractor install them. I went out to check the systems, and they were installed correctly. I configured the solar and generator backup charging systems for the charge profile recommended by the battery manufacturer. The systems ran fine for 3 years, then began having capacity problems. The backup generator was automatically coming online more and more to take over for the failing batteries. In 2013, I had him buy flooded lead/acid batteries, Trojan L-16H. I installed them myself, and reconfigured the charging systems for the battery profile. Those battery banks are still in operation today. So, that again confirmed my earlier AGM experience, but with modern AGM batteries.

I will never buy AGM type batteries for off-grid systems. The battery companies love them, because they do not last as long as properly maintained flooded lead/acid batteries. There is no justification for the higher price when they last half as long or less than the flooded batteries. I just gave away fully functional 12 year old flooded lead/acid 125 Amp/Hr 12V batteries earlier this year, because I bought a replacement battery bank of Trojan L-16H batteries for my own solar power system. The guy I gave them to put them in his logging trucks and heavy equipment. He bragged that they are better than the new batteries he had bought. I guess that's from being connected to Battery Smackers for years!

There is so little water in AGM batteries, that they are ruined very quickly by gassing, which is what most lead/acid charging systems do in order to stir the electrolyte to prevent stratification. So you must set the charging profile to exactly match not only the profile, but the manufacturers brand name, of the AGM batteries purchased. Most of these renewable energy systems only have a single profile for ALL AGM batteries, while the charging profile is very specific for each and every manufacturers brand. This is because different brands have differing concentrations of sulfuric acid in the fiberglass mats, which directly affects cell voltage (hence charging profile) of the batteries.

The battery smacker IS compatible with AGM... The difference is, less longitudinal energy is absorbed per battery because of the very small amount of water per cell. The battery smacker will not increase out gassing, but the renewable energy charging systems can, if not set precisely. If the batteries lose too much moisture, there is not enough water left to absorb the longitudinal energy. This is why more batteries in parallel is much better. If those AGM batteries dry out, damage to electronics can occur from excess unabsorbed longitudinal energy spreading out through the electrical power bus to inverters and other electronics being powered. The flooded batteries normally absorb ALL of that energy, the water soaks it up!


The Battery Smacker is Single phase output, that takes power from a wall wart transformer (AC to DC). 15 volts DC and approx. .10 to .5 amps (1.5 to 7.5 watts of electromagnetic power from the wall socket converted by the transformer to DC current) The few watts of power is only running the microprocessor and mosfet driver and fet. It creates short output pulses. The Battery Smacker has 2 toroids inside, one is the longitudinal inductor toroid (-) and the 2nd one is a RF choke or anti-toroid (+) in which removes the longitudinal energy, so that is does not damage the electronics in which what it is hooked up too. ( for instance, frying the wall wart, or your solar panel controller ) The inductor toroid inside is a mini radiant energy capturer, ( not a typical transformer.) The Battery Smacker is a femtosecond pulse generator cycling between 2 programs. The adjust pot. varies the ratio of time spent on each program. The Battery Smacker circuit will de-sulfate and also charge the battery that it is hooked up to. The Battery Smacker is driven with non-hertzian energy ( also called longitudinal energy) that runs 2 programs from the micro processor. 1) transverse output and a 2) a non-hertzian output. It switches back and forth between the 2 outputs. Designed to charge and de sulfate your batteries. You can adjust these 2 programs to go one side or the other with a potentiometer on the side of he box. It works very well for de sulfating batteries! and also will charge your batteries at night, with no sun. No moving parts! Will last a long time. Two year warranty.
