what is the use of distilled water in battery
Distilled water Distilled water is also commonly used to top off lead acid batteries used in cars and trucks. The presence of other ions commonly found in tap water will drastically reduce an automobile battery's lifespan.
Electrolysis of water This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.
Base oil The least refined type which produced by Solvent Refining. It usually consists of conventional petroleum base oils.
Lithium-ion battery For notebooks or laptops, lithium-ion cells are supplied as part of a battery pack with temperature sensors, voltage converter/regulator circuit, voltage tap, battery charge state monitor and the main connector. These components monitor the state of charge and current in and out of each cell, capacities of each individual cell (drastic change can lead to reverse polarities which is dangerous),[76][unreliable source?] and temperature of each cell and minimize the risk of short circuits.[77]
