What is a 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.

Are lead-acid batteries a good choice?

Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by starter motors.

What is a lead acid battery?

1. Sealed Lead–Acid (SLA): Widely employed in small UPS systems, emergency lighting, and wheelchairs. SLA batteries are preferred in healthcare settings like hospitals and retirement homes due to their affordability, reliability, and minimal maintenance requirements. 2.

What is a flooded lead-acid battery?

Flooded lead-acid batteries, also known as wet-cell batteries: Flooded lead-acid batteries have liquid electrolyte that circulates freely between the lead plates. These batteries require regular maintenance, as the water that evaporates with time needs to be regularly replenished and electrolyte levels need to be monitored.

What are valve regulated lead-acid batteries?

Valve-regulated lead-acid batteries (VRLA batteries), also known as sealed lead-acid batteries (SLA batteries): These batteries are sealed, meaning electrolyte cannot leak or spill out. They also don’t require adding water to the cells, which makes them maintenance-free.

Do lead-acid batteries use relativity?

It was discovered early in 2011 that lead–acid batteries do in fact use some aspects of relativity to function, and to a lesser degree liquid metal and molten-salt batteries such as the Ca–Sb and Sn–Bi also use this effect. 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water.
