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

But lots of men and women 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 easy tips and techniques 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 anyone will be able to perform these (even if you know nothing about cars or car batteries).

So let’s begin! …

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 called the battery’s”Calendar Life” and it’s 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”…

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

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

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

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

  • Decline is a slow process, but one which gradually 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 begin your car for work).

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

Tip 1: Do a monthly review of the battery terminals to be certain they are clean and corrosion free.   One of the initial problems most people have with their car battery is the build-up of rust around the terminals.   Corrosion destroys the connection between the battery and the vehicle and many batteries are replaced due to too much corrosive build up.   But often times, this can be readily 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 at the DIY anti-corrosion paste will eat the corrosion away.   Make certain to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Don’t run any car accessories (radio, lights, 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 car battery after the battery has a voltage drop.   But if the car is not 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 automobile batteries aren’t meant for this type of use.

Rather, car batteries are meant to provide 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 that powers electronics, rather than a battery that just provides you a burst of electricity 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 needs 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 while creating a safety 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.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car battery from large changes in temperature will help maximize 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 does not 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 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 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 vehicle is off.  That happens because current is drawn from the battery by car accessories (radio, lights, etc.) or even the car computers.   This is why people come home from long vacations and find their car battery dead.  

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 this by providing enough electricity for the car accessories and car computer, so they do not always draw current from the car battery when the car is off.   As you can imagine, these chargers are very useful…especially if you go on a trip or leave your car unused for some time.  They’re also helpful 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 so can 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 tip is…make 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 vehicle battery’s water level.   Most car batteries indicate whether there’s a need for water.   So check the vehicle battery water level indicator regularly and when 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.   Never overcharge your car battery. Lead-acid batteries release oxygen and hydrogen gases when they are overcharged.  

  1. It can be volatile.

Tip 8: Assess your car’s alternator.   If you’re doing everything we’ve recommended in this guide but your automobile batteries are dying early, you will want to look at your car’s alternator (or find 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.
