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.

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 simple 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 simple 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 Lifespan Has A Limit (but 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 called 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 complete”Calendar Life”…

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

Lead acid batteries are the earliest, most reliable, 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 stage, which we attempt to maintain for as long as you can.

  • 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 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 not able to start 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 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 several batteries are replaced because of a lot of corrosive build up.   But often times, this can be easily treated by simply 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 acidity in the Cola or the alkaline properties in the DIY anti-corrosion paste will eat the rust away.   After the corrosion is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

Tip 2: Do not run any car accessories (radio, lights, or electronics) before turning on the vehicle ignition and driving the car.   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 is not on, and you are using the car’s electronics, you are simply relying on the car battery to power those electronic equipment. 

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 could be for).   Using your car battery for a battery that powers electronics, instead of a battery that just gives you a burst of electricity for ignition, will damage the battery and significantly shorten it’s lifespan if it’s repeatedly used in this fashion.   So avoid operating any automobile accessories or electronics while the car is off.

Tip 3: Make sure the car battery is safe and has good battery cables.   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 cause damage to your car whilst creating a security risk.   The same could happen if you have awful battery cables (or they’re not connected properly).  So check your cables and be sure they have a secure connection as well.

Protecting your car battery from big 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 doesn’t 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 place in your car model and year, and it will tell you if your battery will match their kit — like here (top of page).   These protective battery sleeves are usually made of 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 car is off.  That happens because current is drawn from the battery by car accessories (radio, lights, etc.) or even the automobile computers.   This is why people come home from long holidays and find their car battery dead.   But to prevent this, you can use either a car battery charger or a solar battery charger. 

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 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 car is off.   As you can imagine, these chargers are extremely useful…especially if you go on a trip or leave your car unused for some time.  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 so will dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully control.   The most important thing to remember with this suggestion is…make sure you fully charge your car battery at least once a week because it’ll greatly increase the life span 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 if there’s a need for water.   So check the car battery water level indicator frequently and when 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 oxygen and hydrogen 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 — which shortens its lifespan

Tip 8: Assess your car’s alternator.   If you are doing everything we’ve recommended in this article but your car batteries are still dying early, you’ll want to check 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.
