Write the chemistry of recharging the lead storage battery?

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.

Lead–acid batteries (under 5 kg) account for 1.5% of all portable secondary battery sales in Japan by number of units sold (25% by price).^[1] Sealed lead–acid batteries accounted for 10% by weight of all portable battery sales in the EU in 2000
