Below is just one of our Case Stories about how we were presented with a design problem and solved it to create a viable, producible and profitable product for the client.

We welcome your inquiries on how we might add value to your product line.

Robert J. Mulligan-President
Bradenton, FL

Designed, Produced 400,000 small Solar Panels
for a major U.S. Military Battery Component Manufacturer.

This battery conditioning product had bounced around with three firms before it became successful and found a proper market. PHOTON TECHNOLOGIES was involved with the original inventor, the two subsequent firms and the final producer who made the product a great success.

The inventor of this battery de-sulfating product discovered a unique characteristic of older batteries and how a typical lead-acid battery ages, especially due to low charging levels.

When a common lead-acid battery as is used in cars, trucks, boats and military vehicles stays uncharged for a period of time the battery lead plates become coated with sulfation crystals which come from the sulfuric acid within the battery. As the hard dense crystals become attached to the plates, the specific gravity of the sulfuric acid becomes lower (as can be measured with a hydrometer). In other words, the water portion of the acid solution becomes higher as the sulfation crystals are deposited onto the plates.

When the sulfation crystals coat the plates, the electric energy stored in the plates cannot come out and new electrical energy cannot be absorbed. The sulfation crystals become an insulator to prevent recharging and discharging.

A common method of rebuilding a older, "sulfated" batteries is to expose them to a high DC voltage, typically 16 to 20 volts, which will tend to overheat the battery plates and force the sulfation crystals to become dislodged from the plates, which then fall to the bottom of the battery case. The problem with this method of desulfation is that it can warp the plates so that they short out by touching each other, and the hard crystals can be come dense enough at the bottom of the case that they also will short out the plates.

Overvoltage charging of a lead-acid battery to break the sulfation crystals is not an ideal solution to renew an older battery since it can be destructive and may lead to an early end to the battery’s life.

The original inventor of the desulfation technology that PHOTON TECHNOLOGY involved with, discovered that the sulfation crystals had a particular "resonance" frequency where they would dissolve back into the sulfuric acid solution, on a molecular level, not in "chunks" that settle to the battery case bottom.

The first several producers of this unique product, all powered by PHOTON TECHNOLOGIES small solar panels, aimed their solar powered battery desulfation products toward the consumer market, thinking that the average battery owner would prefer to extend the lifetime of their boat, car, truck or tractor battery by attaching the battery desulfator to the battery +/- terminals from time to time to do maintenance "cleaning" of the battery plates.

Unfortunately, the average consumer thought that the product was just another quick-fix gimmick plus the cost of the original versions of the product was higher than the cost of simply buying a new battery, therefore, while the technology was valid, the market focus was not.

The final and successful owner of the patent and technology ignored the previous ventures and took a close look at markets that:

1-Needed batteries that were always capable of being fully recharged and discharged.

2-Needed batteries that were immediately ready to use.

3-Eliminated the need for long-lead time replacement of specialized batteries.

4-Could afford a higher cost product based on the above needs and would purchase high volume, repeat orders.

That market was the United States military.

The U.S. Military had faced many years of transit and fighting type vehicles held in their depots because the batteries which were responsible for starting these large diesel and turbine engines had degraded due to battery sulfation an d could not realistically be used dependably in fighting and support vehicles.

The large scale introduction of the new version of the solar powered battery desulfation was an immediate success. PHOTON TECHNOLOGIES designed the solar panel used in this product and produced close to a half million of them for the solar battery pulsing product.
