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 vehicle’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 prevent this from happening.

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

The tips we’ll teach you in this guide will be easy to do…and anybody will be able 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’s 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 one 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.

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

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

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

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

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

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

Batteries in decline can still 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 until a problem arises (like being not able to begin your car for work).

Tip 1: Do a monthly review of the battery terminals to make sure 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 several batteries are replaced because of a lot of corrosive build up.   But often times, this can be readily treated simply by pouring a small amount of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) within the corroded areas. 

The acidity in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the rust away.   After the rust is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

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

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

Instead, car batteries are meant to offer a sudden burst of electricity for ignition.  They are not made to offer prolonged power for electronics and other devices (that is what a deep cycle lead acid battery would be for).   Using your car battery for a battery which powers electronics, instead of 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 utilized in this fashion.   So avoid operating any car accessories or electronics while the car is off.

Tip 3: Make sure the car battery is safe and has great battery cables.   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 damage your car whilst creating a security risk.   The same could happen if you have bad battery cables (or they are not connected properly).  So check your cables and be 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 install 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 website where you can place in your car model and year, and it’ll tell you if your battery will fit their kit — like here (top of page).   These protective battery sleeves are typically made of plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and protect it while still allowing proper ventilation.

Tip 5: Fully charge 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.  That 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 holidays and find their car battery dead.  

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the car is not in use.   They do it by providing enough power for the car accessories and car computer, so that they do not always draw current from the car battery when the car is off.   They’re also useful if you go on plenty 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 enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully charge.   The most important thing to remember with this tip is…make sure you fully charge your car battery at least once a week because it will greatly increase the life of your battery.  Do this with a charger, interchanging batteries…or simply 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 required, 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 hydrogen and oxygen gases when they’re overcharged.  

  1. It can be volatile.

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