Seal lead acid Battery

Lead-acid batteries have been known for a substantially long period of time and have been employed commercially in a relatively wide variety of applications. Lead-acid batteries have been used for many diverse applications. Such applications include use as a starting, lighting and ignition power source for vehicles (SLI), use in marine batteries for starting, lighting and other auxiliary power requirements, as a motive power source for use in golf carts and other vehicles and other applications of this sort. Lead-acid batteries have been employed in a variety of stand-by power applications to provide a power source when the main power source becomes inoperable. Lead-acid batteries have also been employed in many other applications, e.g., uniform power distribution, power damping applications, and even for small electronic devices such as video cameras and cassette players. In general, a lead acid battery is a battery which has a stable characteristic at a lower cost as a secondary battery and which is used widely as an electric power source of a movable type for use in a portable electronic apparatus, a starter for automobile or a golf cart and a stationary type for use in a back up electric source for computer. The lead-acid electrochemical system has provided a reliable energy source which is capable of being manufactured in automated production while providing acceptable quality. Based on the quantity of acid present in a battery, lead-acid batteries are classified as either flooded or starved electrolyte batteries.
