8 Simple Tips & Trick To Extend The Life Of Your Car Battery

Your car battery should last about 3 to 5 years…

But lots of people find that they have to modify their car battery every 1 to 2 years.

And what can you do to prolong your car’s battery life?

Well… That’s what we’ll discuss in this article.

We’ll show you why car batteries die early…and what you can do to keep this from happening.

We’ll also offer you 8 simple tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we will teach you in this guide will be simple to do…and anybody will have the ability to do these (even if you know nothing about cars or car batteries).

So let’s begin! …

First, You Ought to Know That Every Car Battery Lifespan Has A Limit (however most people kill their battery well before it’s time)

Even if you care for your car battery perfectly…it will still die 1 day.

This set lifespan is known as the battery’s”Calendar Life” and it is completely independent of how many times the battery has been charged or discharged.

Once a battery reaches the end of its”Calendar Life” it will become unusable.

However, most car batteries never make it their full”Calendar Life”…

Instead, they die early because of poor maintenance and maintenance…that you can do something about.

A Little Background About Lead Acid Batteries Before Our 8 Battery Tips and Tricks…

Lead acid batteries are the earliest, most dependable, and most widely used form of rechargeable battery in the world.

  • Formatting is when the battery is new and needs to be used gently.

  • Peak is the perfect performance stage, which we attempt to keep for as long as possible.

  • Decline is a slow process, but one that gradually ends in the conclusion of the battery.

Batteries in decline can still be used for quite a while, but must be watched.

Around this time, you can either recondition the battery or keep a close eye on it and try to replace it before a problem arises (like being unable to begin your car for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they’re clean and rust free.   One of the initial problems most people have with their car battery is the build-up of corrosion around the terminals.   Corrosion destroys the connection between the battery and the car and many batteries are replaced due to a lot of corrosive build up.   But often times, this can be readily treated by simply pouring a small amount of Cola or a DIY anti-corrosion glue (one part water to three parts baking soda) over the corroded areas. 

The acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will consume the rust away.  

Tip 2: Don’t run any car accessories (lights, radio, or electronics) before turning on the car ignition and driving the vehicle.   When the vehicle is on, the car alternator generates electricity and charges the vehicle battery after the battery has a voltage drop.   But if the car isn’t on, and you’re using the car’s electronics, you’re simply relying on the car battery to power those electronics. 

This is detrimental to the car battery because automobile batteries aren’t meant for this sort of use.

Rather, car batteries are supposed to provide a sudden burst of electricity for ignition.  They are not made to provide prolonged power for electronics and other devices (that is what a deep cycle lead acid battery would be for).   Using your car battery as a battery which powers electronics, instead of a battery that just provides you a burst of power for ignition, will damage the battery and greatly shorten it’s lifespan if it’s repeatedly used in this fashion.   So avoid operating any car accessories or electronics while the vehicle is off.

Tip 3: Make sure the car battery is safe and has great battery wires.   The battery needs to be secured at all times.  If a battery is jostling around it will be impaired and might short circuit.   This will ruin the battery — and even damage your car whilst creating a security risk.   The same could happen if you have bad battery cables (or they’re not connected correctly ).  So check your cables and make sure they have a secure connection as well.

Protecting your car battery from large changes in temperature will help optimize the battery’s lifespan.   To do this you can use a car battery insulation kit.   Newer model cars currently have these kits installed typically.  But if your car does not have one, you can easily set up one yourself.   Just be certain it matches your car’s battery compartment.  Generally the companies selling these battery insulation kits will have a form on their site where you can put in your car model and year, and it will tell you if your battery will fit their kit — such as here (top of page).   These protective battery sleeves are usually made from plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and guard it while still allowing proper ventilation.

Tip 5: Fully control your car battery at least once a week (use a car battery charger or interchange batteries if you have to).   Your car battery drains even when the vehicle is off.  This happens because current is drawn from the battery by car accessories (radio, lights, etc.) or the automobile computers.   This is the reason why folks come home from long vacations and locate their car battery dead.   But to prevent this, you can use either a car battery charger or a solar battery charger. 

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the car is not in use.   They do it by providing enough electricity for the car accessories and car computer, so that they don’t continuously draw current from the vehicle battery when the vehicle is off.   As you can imagine, these chargers are very useful…especially if you go on a trip or leave your car unused for a while.  They’re also useful if you go on a lot of short car trips (like to work and back daily ) and never give your battery a opportunity to fully recharge.  Repeatedly doing this will dramatically shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully control.   The main thing to remember with this suggestion is…be sure you fully charge your car battery at least once a week since it will greatly increase the life span of your battery.  Do this with a charger, interchanging batteries…or just going on a car ride long enough to recharge the battery.

Tip 6: Assess your car battery’s water level.   Most car batteries indicate if there is a need for water.   So check the car battery water level indicator frequently and if water is needed, refill the battery with distilled water (and that is significant, ONLY use distilled water to refill your car battery).

Tip 7: Do NOT overcharge your car battery.   Lead-acid batteries release hydrogen and oxygen gases when they’re overcharged.  

  1. It can be explosive.

  2. It also breaks down the composition of the water in the battery — that shortens its lifespan

Tip 8: Assess your car’s alternator.   If you are doing everything we’ve recommended in this article but your automobile batteries are still dying early, you will want to look at your car’s alternator (or get a mechanic to check it).   If your alternator is bad it will results in ineffective recharging of your battery and dramatically shorten your battery’s lifespan.
