The 5 Functions Of A Car Battery—And How They Influence Products

“Basics”—often a humdrum of out of context garble. “The basics” saying is holding for this piece today, though, and it influences battery products the next time you go shopping. Get to know some of the 5 functions of a car battery (to start, at least) and track down the next “best” battery that “fits the bill.”

What Are The Functions Of A Car Battery—Does It End With Just Five, Though?

The battery of a car (as we see today) is usually useful when it comes to several vital functions (“5” just being a start) for your car vehicles:


1. A battery stores chemical material for conversion to electrical energy.
2. A battery starts up the ignition system of your vehicle.
3. A battery keeps the energy system of your vehicle sustainable.
4. A battery transfers initial currents of energy over to an alternate performance system of your vehicle (an alternator).
5. A battery receives and gets a regulation update from a measuring system to keep enough ‘charge’ for the next ‘startup’ session (a regulator for voltage).


It is also important to note that aside from the functions above, most customers/consumers primarily for one particular purpose.


• The battery as a starter and cranking (“strong” cranking at that) is usually a requirement so that the engine gets enough of currents of energy.


• The engine of your car will usually contain an alternator, which takes the transference of those energy currents from the starting process—and sustains the energy from there.

Historically, in the ’50s, it was typical for more significant (and instead space-consuming) variations of the modern car battery we know of today.

Here are some of the exemplary functions of the starter car battery back in the old days:

• Motor units that can often fill up almost an entire field—relatively speaking, of course
• Batteries that often use oils for motors that belong to the highly viscous category, which can be quite wasteful to the environment
• Amperage for cold cranking of around (at the least) four hundred for engines to start-up or “crank” in harsh weather conditions
• Batteries that usually contain a much longer time for actually delivering the cranking process in a typical session (yikes)
• Also, engines of the system often operate on massive carbon action along with the gasoline—not so environment-friendly, relatively speaking

Most of the starter battery today is, of course, relatively safer but also more convenient in part due to a bunch of improvements prevalent of our age.


• Cutting edge technology for the ignition system; utilizing different connector systems that link both the methods for electric and security features of the vehicle.
• Batteries today can create a new network system that reduces corrosive damage and other performance problems.
• The new improvement in batteries helps the battery not to drain too much of its energy.
• Modern batteries can absorb varying electric spikes when it comes to voltage
• The cells today can now act as an absorbing platform for different harmful situations.

The improvements in the reference above, mind you, are just some of the features that are in prominence in our day and age for the battery automotive
The above makes sense because the compact nature of newer systems saves for a lot of space and energy.

Curious Question: Why Do Cars Need Batteries, Anyway?

This issue is a good question and one in which it will (probably) surprise no one that a battery is useful for just about a lot of things we enjoy today.


• An array is a summary or makeup of chemical processes that turn into electric units that a vehicle (literally) can use—your car, in this case.
To add some proximity for an example in comparison, let us compare a key component in the human body with that of a battery.


• There are mitochondria, which is a storage house for our human cells—from blood to bones, as is the case.


• There is a battery cell, which is a storage house for the cells that can convert chemicals to electricity—from your battery product to your vehicle’s engine.

On that note, here is a quick rundown on a battery cell’s chemical – electronic exchange process:

1. Batteries usually go with a standard 6-cell format that produces around 2 voltage units, and each one of the cells possesses 2-plates around them (grid-like lead materials)—this your standard 12v battery unit.
2. The plates often take a dip in a surrounding battery acid (Sulphur acid)—from there, movement of the 2-plates “ignites” (so to speak), acting the catalyst process.
3. This movement of acid will produce in one of the leads plates (dioxide) a bunch of lead base sulfate and some ion components.
4. The movement of the plate of dioxide (lead) now produces a reaction to the plate adjacent to it—producing both hydrogen and lead base sulfate
5. The previous steps then create a result that provides electron components, which swirl around for an overall electric generation
6. The movements then go around the terminals of the battery, all the way to your vehicle’s engine.

NOTE: The connector cables, as well as your terminals in the battery, are partly responsible for why you can kind of “jump” process an array when it is at discharge, so the chemical – electrical exchange process goes both ways, friends.

Where Is Battery In Car (Yours), In Terms Of Location?

You can pretty much find the location in the form of a “box” like the structure of your car’s front-engine—you will need to lift the cover at the front, of course.

It will also be evident to notice that along with the shape of your battery (often “box” like too), your car’s engine will possess spaces for specific tools.


• Terminal points for junctures
• Connector points for cables

Though not part of the five functions of a car battery in the discussion, you will still need to know where the location of your car’s engine in case you want to jumpstart a dead car battery, too, anyway.
