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

But many men and women find that they have to change their car battery every 1 to 2 years.

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

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 easy tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we will teach you in this article will be easy to do…and anyone will have the ability to perform 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 (however most people kill their battery well before it’s time)

Even if you take care of your car battery perfectly…it will still die one day.

This set lifespan is known as the battery’s”Calendar Life” and it’s completely independent of how many times 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 complete”Calendar Life”…

Rather, they die early due to 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 type of rechargeable battery in the world.

Lead Acid Batteries have three life phases — formatting, peak, and decline.

  • 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 you can.

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

Batteries in decline can still be used for quite some time, but must be watched.

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

Tip 1: Do a monthly review of the battery terminals to be certain they are clean and corrosion 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 vehicle and many batteries are replaced because of too much corrosive build up.   But often times, this is easily treated by simply pouring a small quantity of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) over the corroded areas. 

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

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

This is detrimental to the car battery because car batteries are not meant for this type of use.

Instead, car batteries are supposed to provide a sudden burst of power for ignition.  They are 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 that powers electronics, rather than a battery that just gives 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 automobile accessories or electronics while the vehicle is off.

Tip 3: Make sure the car battery is secure and has great battery cables.   The battery has to be secured at all times.  If a battery is jostling around it will 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 awful battery cables (or they are not connected properly).  So check your cables and make sure they have a secure connection also.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your vehicle battery from big changes in temperature will help optimize the battery’s lifespan.   To do this you can use a car battery insulating material.   Newer model cars already have these kits installed typically.  But if your car doesn’t have one, you can easily set up one yourself.   Just make sure 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 place in your car model and year, and it’ll 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 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.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the car computers.   This is the reason why people come home from long holidays and locate their car battery dead.  

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the vehicle is not being used.   They do this by providing enough electricity for your car accessories and car computer, so they do not always draw current from the vehicle battery when the vehicle is off.   They’re also useful if you go on a lot of short car trips (like to work and back each day) 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 you at home to fully charge.   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’ll 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 whether there is a demand for water.   So check the vehicle battery water level indicator frequently and if water is required, refill the battery with distilled water (and that is significant, ONLY use distilled water to refill your car battery).

Lead-acid batteries release hydrogen and oxygen gases when they’re overcharged.   This causes two problems:

  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 vehicle’s alternator.   If you’re doing everything we’ve recommended in this guide but your automobile batteries are dying early, you will want to check your car’s alternator (or get a mechanic to check it).
