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

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

Why is this?

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 automobile batteries die early…and what you can do to keep this from happening.

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

The tips we’ll teach you in this article will be easy to do…and anyone will have the ability to do these (even if you know nothing about cars or car batteries).

So let’s get started! …

First, You Should Know That Every Car Battery Lifespan Has A Limit (but 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 often the battery was charged or discharged.

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

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

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

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

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

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

  • Decline is a slow process, but one which slowly ends in the termination of the battery.

Batteries in decline can nevertheless be used for quite some time, 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).

8 Simple Tips To Prolong The Life Of Your Car’s Lead Acid Battery

Tip 1: Do a monthly inspection of the battery terminals to be certain they are clean and rust free.   One of the first 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 because of a lot of corrosive build up.   But often times, this is easily treated simply by pouring a small quantity of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) within the corroded areas. 

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

Tip 2: Do not run any car accessories (lights, radio, or electronics) before turning on the car ignition and driving the vehicle.   When the car is on, the auto 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 just relying on the car battery to power those electronics. 

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

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

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

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 doesn’t have one, you can easily set up one yourself.   Just make sure it fits your car’s battery compartment.  Generally the companies selling these battery insulation kits will have a form on their site where you can place in your car model and year, and it will tell you if your battery will match their kit — such as here (top of page).   These protective battery sleeves are typically made from plastic or an acid resistant, thermal resistant material.   These car battery insulation kits will insulate your battery and protect it while still allowing appropriate ventilation.

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

Car battery chargers (regular or solar) will keep the optimum charge level of your car battery when the car is not in use.   They do this by providing enough power for your car accessories and car computer, so they don’t always draw current from the car battery when the vehicle is off.   They’re also helpful if you go on plenty of short car trips (like to work and back each day) and never give your battery a chance to fully recharge.  Repeatedly doing this can dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully control.   The most important thing to remember with this suggestion is…be sure you fully charge your car battery at least once a week because it will greatly increase the life of your battery.  Do this using 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’s a demand for water.   So check the car battery water level indicator regularly and when water is needed, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your vehicle battery).

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

  1. It can be explosive.

Tip 8: Check your car’s alternator.   If you are doing everything we have recommended in this guide but your car batteries are still dying early, you’ll want to look at your car’s alternator (or get a mechanic to check it).
