Car Tips: Everything You Need to Know About Your Auto Battery

Do you know enough about your car battery? Not sure exactly how a car battery works?

A car battery is responsible for starting your car, so it’s important that you understand it fully. Getting the right car battery and ensuring that it’s well taken care of is essential for avoiding starting problems and keeping your car running strong.

Fortunately, we’re here to help. In this car tips guide, we’ll tell you everything you need to know about car batteries.

What Does a Car Battery Do?

A car battery provides electricity to your vehicle and helps to power all of the electrical workings of your car. The battery is absolutely essential for your vehicle and helps with a lot of different functions including starting the engine, delivering electricity to the ignition, powering lights and electronics, and more.

A car battery works by converting chemical energy into electrical energy. The energy is released as a direct current and works to provide your vehicle with what it needs for electrical functionality.

In addition to providing energy for starting a car, a battery also works to keep the electric current consistent and steady. It stabilizes the voltage to keep the engine running.

The car battery is extremely important for a vehicle so it’s crucial that it’s working well. When it stops working, you’ll begin to have problems starting your car.

It’s important to get car batteries from a great source and to ensure that any battery you use is made by a reliable manufacturer. You may want to check out if you’re looking for a great car battery.

Different Types of Car Batteries

There are several different types of car batteries and they have different classifications.

These batteries all have a lot of similarities but there are also many differences to be aware of as well. Lifespans, maintenance needs, and strength will all be different with each type of battery.

Here are some of the main types of car batteries that you should know about.

1. Starting, Lighting, and Ignition (SLI) Batteries

A starting, lighting, and ignition battery is a basic type of car battery that is designed to start and run a vehicle and maintain power for electrical systems.

These car batteries are widely available and often come with a new car. They are also maintenance-free.

2. Deep-Cycle Batteries

A deep-cycle battery is a type of battery that offers sustained energy over a long period of time. These batteries are designed to be able to be discharged repeatedly.

While these batteries are primarily used for smaller vehicles such as golf carts and jet-skis, some electric cars will use these batteries as well.

3. VRLA/SLA Batteries

Valve-regulated lead-acid (VRLA) batteries and sealed lead-acid (SLA) batteries are the same. These are batteries that are sealed and that won’t spill if they’re tipped over.

These batteries are made to be very low-maintenance. However, they are unable to be fixed, so you’ll need to get a full replacement if a VRLA battery stops working.

There are two main types of VRLA batteries and these include Absorption Glass Mat (AGM) and Gel Cell batteries.

4. Wet Cell/Flooded Batteries

Flooded car batteries are also known as wet cell batteries and are another option that you can consider using for a vehicle.

These car batteries need an electrolyte solution to work and are similar to AGM batteries. However, unlike AGM batteries, they don’t need a fiberglass mat.

Unlike some other types of batteries, it will be necessary to perform maintenance on these batteries. They’ll need to be inspected regularly and should be replenished with electrolytes.

5. Li-Ion Car Batteries

Li-Ion car batteries are another type of car battery that may be used to provide power to a vehicle. These batteries are rechargeable, and while they are commonly found in consumer electronics, they are often used in electric and hybrid vehicles as well. 

When compared to typical lead-acid or nickel-cadmium rechargeable batteries, these batteries have a higher energy density. These batteries are small and compact and can be charged quickly and efficiently.

Understanding Battery Specifications

There are several key terms related to battery specifications that you should know about and consider when choosing a car battery. Make sure that you know what these are and think about them when choosing a battery for your vehicle.

Here are some of the main terms related to car batteries that you should be aware of.

BCI Number/Group Number

The BCI number, also known as a group number, states the battery’s size and dimensions including length, width, and height. The number also states the location of the terminals as well as their polarity.

You’ll need to be sure to buy a battery that has the right dimensions and polarity for your vehicle.

Cranking Amps (CCA)

Cold-cranking amps are also important to know about. A CCA rating states the number of amps that the battery is able to deliver at 0°F for 30 seconds without dropping below 7.2 volts and becoming unusable.

Without enough cold-cranking amps, the battery will be unable to start your vehicle in cold temperatures.

Reserve Capacity (RC)

Reserve capacity is another important term to know about when trying to understand more about your car battery.

This is an indicator of the length of time that a fully charged car battery will be able to operate if your car’s alternator fails. Having a reserve capacity of at least 25 amps is essential.
