All You Need To Know about Lead-Acid Batteries


Lead-acid batteries have been the dominant technology in automotive batteries since it was invented. There have been many advancements in lead-acid battery technology since then, and today’s batteries are much more reliable, longer lasting and environmentally friendly than their predecessors of the late 19th century. If you are looking for lead-acid car battery for sale, you’re in the right page. In this article, we’ll go over some of the most important lead-acid battery technologies, car batteries prices and some of the best benefits they provide consumers like you.

What Are Lead-Acid Batteries?

The lead-acid battery is a type of battery that uses lead and sulphuric acid as its electrolyte and it was the first rechargeable battery. Lead is a chemical element with atomic number 82, sulphur is a non-metal with atomic number 16, and the chemical formula for sulphuric acid is H2SO4. There are many types of lead-acid batteries, but the most common one you will see at an auto repair shop or gas station is called the wet cell.

How Do Lead-Acid Batteries Work?

A lead acid battery is made up of two electrodes, a negative cathode and a positive anode, which are separated by a liquid electrolyte. This liquid is usually a sulphuric acid solution. When the battery is being charged, the electric current from the charger provides electrons to the cathode (negative) side of the battery. At this point, some of these electrons find their way into the electrolyte and react with sulphuric acid to produce hydrogen gas and lead sulphate on that electrode.

A lead-acid battery is a type of rechargeable battery that uses lead plates immersed in an acid electrolyte to generate electric current. Lead-acid batteries are used in automobiles, trucks, and other vehicles because they are inexpensive, reliable and can be easily recharged by connecting them to a charging device. The voltage generated by the battery is 2 volts per cell so a 12 volt car battery will have 6 cells inside it.

What Are The Benefits Of Lead-Acid Batteries?

There are a number of benefits to lead-acid batteries. Compared to the other type car batteries prices, lead-acid battery are inexpensive, easy to maintain, and have been around for a long time. They don’t require any maintenance at all and can be left in storage for years without damaging the battery. Lead acid batteries also have very low self-discharge rates, which means that they will still hold their charge when sitting idle for months at a time. Least of all, these batteries are environmentally friendly because they don’t contain any harmful chemicals or heavy metals.

How Long Do Lead-Acid Batteries Last?

One of the most important things to know about automotive batteries is how long they last. When a battery is new, it can provide up to 80% of its original capacity. Over time, the battery loses its ability to hold a charge, and may need to be replaced after five years or less. Some lead-acid batteries are designed with reserve capacities that allow them to function for 10 or more years without additional charging. These so-called deep cycle lead acid batteries are ideal for use in power tools like lawn mowers and chainsaws, but they require careful maintenance. If left unused for too long, the chemicals in these batteries will degrade over time and eventually render them unusable.
