As they are not expensive compared to newer technologies, lead–acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities.
Energy density is very important for battery performance. It affects how big and heavy a battery can be. More energy density means batteries can be smaller and lighter. This is great for making thinner phones, longer-range electric cars, and more efficient drones. It also helps make batteries cheaper by needing less material.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts.
