Invented in 1859 by French physicist Gaston Plant, lead acid battery is 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 motor vehicles to provide the high current required by automobile starter motors.

A lead acid battery is an electrical storage device that uses a reversible chemical reaction to store energy. It uses a combination of lead plates or grids and an electrolyte consisting of a diluted sulphuric acid to convert lectrical energy into potential chemical energy and back again. The electrolyte of lead-acid batteries is hazardous to your health and may produce burns and other permanent damage if you come into contact with it!

Lead-acid battery industry, the country’s environmental shock wave continues, the industry did not expect is that not only environmental standards by the policy impact of small businesses, some large enterprises also was ordered to suspend production for rectification, lead-acid battery industry is almost across the board suffer. Requirements for protection from the current situation appears too high is a factor, China Battery Industry Association, vice president of full-time Wang Jing Zhong said that if by some provinces in the implementation of the 500-meter distance protection requirements, very few companies

In general, lead acid battery is damaged in terms of capacity and service life if discharged below the recommended cut-off voltages. It is widely recognized that the lead calcium alloy grid batteries are susceptible to over discharge damage. For example, if a lead acid battery was discharged to zero (0) volts, and left standing in either open circuit or on load for a long period of time, severe sulphation would occur, raising the internal resistance of the battery to an abnormally high level. In such an extreme case, the battery would not accept charge. Although over discharging IBT lead acid batteries is not recommended, they have been designed to withstand small levels of over discharge, provided that the battery is not left in a discharged state for a long period of time. It is necessary to avoid the over discharge situation as much as possible. To prevent this from happening, for some applications, it may be possible to incorporate a low voltage alarm and cut off circuit.
