David Energy Inc was established in November1991.We are rejuvenating car batteries for local fleet vehicle cmpanies like taxi, truck and buses. We have our own invented material for desulfation of sulfated lead plates.Our technology BRS material and desulfator, is the unique in the world in efficient desulfation of SULFATED lead plates. Any prematurely dead lead acid battery is rejuvenated by our technology as long as its plates are mechanically sound.Our products are offered under POWERTEC. OEM brands are available for international orders.Currently our batteries or battery desulfating systems are introduced in overseas market like; Phillippines, Indonesia,Nigeria,Mexico,Bangladesh,and Colombia. If you are looking for a new business opportunity, consult us for more information.Also we are buying scrap batteris for local smelter on a large size volume base. We like to grow together with any overseas partners in this area also. Korea has been using lots of scrap batteries for remelting them for lead acid batteries.As one division, we are introducing new fuel saver techniques. Our fuel saver is working by the principle of cavitation. It atomizes liquid fuel when the fuel passes through the changing pressure grooved spaces. It has been tested and proven by Korean Automobile Performance Laboratory. As its special feature as a greenhouse gas reduction function, Chinese company is going to distribute this itm nationwide in this year 2012. We recommend our customers to use EFIE or MAF/MAP enhancers together to ensure the fuel saving results. Otherwise old carburetted car can adopt this device without EFIE or MAP enhancer.The technology is protected by international patents in every country.
