Lead-acid batteries, invented in 1859 by French physicist Gaston Plante, are the oldest type of rechargeable battery. Despite having the second lowest energy-to-weight ratio (next to the nickel-iron battery) and a correspondingly low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in cars to provide the high current required by automobile starter motors.
Meanwhile millions batteries damaging every day, millions dollars wasting every hours, milions pollution hanppenning every second. Because normal work life of a lead acid battery only 2 years[300~500times deep cycle charging]. The 1 AAA battery can pollute 1 square meter earth! How can we do? Accumulator recondition instrument / Battery repair equipment befallen on the world, it's not only can help our human being reduce the pollution and cost, but also can give you a way to feed your family, a chance to come true your future dream. Our job is design more intelligent maintain tools of lead acid battery year by year.
We hope to establish a good relationship with those people whom want to do battery fixing services. It's our both honour to have a chance do this great kind job called environment protect project. For our next generation, next next and next generation, for continued being.
