Scientific Studies Confirm Benefits of Pulse Technology
Recent studies by major universities have confirmed that patented PulseTech® Pulse Technology®, the heart of our battery charging and maintenance systems, provides exceptional benefits to all types of lead-acid batteries.
The studies were conducted in response to a request from the military, scientific and engineering communities for scientific validation of claims that our 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 concluded in the fall of 2000.
Results of the studies confirmed that several significant improvements in lead-acid battery performance are attributable to our PulseTechnology. These improvements are caused by the effect of the technology in reducing the buildup of large lead sulfate crystals on lead-acid battery plates. This buildup is the main cause of battery problems and failure in most vehicles and equipment.
During these studies, x-ray diffraction methods investigated these crystalline buildings regularly. The x-ray diffraction data confirmed the positive effects of pulsing on the battery plate morphology because it showed 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 improve a battery’s ability to accept and store more energy greatly. Because they store more energy, batteries last longer between recharges and are capable of providing more available power than batteries not using our technology.
The effect of the pulsing on the formation of these crystalline structures also increases the battery's durability. PulseTechnology prevents sulfate-induced corrosion that is the primary cause of shedding of active material. By helping prevent shedding, the average life span of the battery can be increased dramatically. Tests show that getting three or more times as many cycles from pulsed batteries as from non-pulsed batteries is possible. As a result, even batteries on frequently - used vehicles and equipment will receive significant benefits.
TESTING ON STORED BATTERIES: During the Oakland University study, testing was also done on stored batteries to determine how PulseTechnology would affect military vehicles that sit unused for long periods of time. The batteries were stored at a constant temperature of 25° C (77° F) for 14 weeks. Some were equipped with Solargizers and others were not.
The final report lists the following results: "There is a distinctive difference in the charge capacity between these two batteries. A battery stored under the influence of pulsation retained its original capacity while the capacity of the battery stored without pulsation lost a considerable amount of charge. The decrease of charge capacity of batteries stored without pulsation decreased linearly with time. After 14 weeks the decrease of charge capacity accounted for about 25% of the battery's original capacity. In this same period of time, the charge of the battery attached to the Solargizer slightly increased. This is probably due to a reconditioning (reforming) process of the battery plates by continuous pulsation.
"Electron scanning microscopy as well as x-ray spectroscopy clearly underline reasons for the preservation process. During the storage of a battery without pulsation, a formation of large crystallographic domains is observed on the surface of positive electrodes. This is in contrast to the morphology of the battery stored with pulses. A smooth, homogeneous surface with significantly smaller crystals was formed during the storage process due to the pulsation effect."
