Sealed Lead-acid battery

About[]

Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a 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.

"Used in vehicles, alarm systems and uninterruptible power supplies. The major advantage of this chemistry is its low cost - a large lead-acid battery (e.g. 70Ah) is relatively inexpensive compared to batteries based on other chemistries, but this is most likely due to its popularity. However, this historically important battery type has a lower energy/mass than other battery types now available." [1]
