   en.wikipedia.org/wiki/Lead–acid_battery

   The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

   In the 20th century most electric vehicles used a flooded lead–acid battery due to their mature technology, high availability, and low cost. Lead–acid batteries powered such early modern EVs as the original 1996 versions of the EV1.

   The main benefit of the lead–acid battery is its low cost; its main drawbacks are large size and weight for a given capacity and voltage. Lead–acid batteries should never be discharged to below 20% of their capacity, [67] because internal resistance will cause heat and damage when they are recharged. Deep-cycle lead–acid systems often use ...

   A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps.. A valve regulated lead‐acid (VRLA) battery, commonly known as a sealed lead-acid (SLA) battery, [1] is a type of lead-acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel, proportioning of the negative and ...

   The sodium-ion battery is meant for stationary storage and competes with lead–acid batteries. It aims at a low total cost of ownership per kWh of storage. This is achieved by a long and stable lifetime. The effective number of cycles is above 5000 and the battery is not damaged by deep discharge.
