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

But many 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?

We’ll show you why car batteries die early…and what you can do to prevent this from happening.

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

The tips we’ll teach you in this article 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 Ought to Know That Every Car Battery’s 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 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.

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

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

A Little Background About Lead Acid Batteries Before Our 8 Battery Tips and Tricks…

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 has to be used lightly.

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

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

Batteries in decline can nevertheless be used for quite a while, but have to be watched.

Around this time, you may 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 start your vehicle for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they are clean and rust 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 car and many batteries are replaced because of a lot of corrosive build up.   But often times, this can be easily treated simply by pouring a small quantity of Cola or a DIY anti-corrosion glue (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 consume the corrosion away.  

Tip 2: Do not run any car accessories (radio, lights, or electronics) before turning on 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 is not on, and you’re using the car’s electronics, you’re 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 sort of use.

Instead, car batteries are supposed to provide a sudden burst of electricity 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 as a battery that powers electronics, rather than 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 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 good battery wires.   The battery has to be secured at all times.  If a battery is jostling around it’ll be impaired and might short circuit.   This may 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 correctly ).  So check your cables and make 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 optimize the battery’s lifespan.   To do this you can use a car battery insulating material.   Newer model cars currently 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 site where you can put 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 typically 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 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 even the automobile computers.   This is the reason 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 it by providing enough electricity for your car accessories and car computer, so that they don’t always draw current from the vehicle 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 useful if you go on a lot of short car trips (like to work and back each day) and never give your battery a chance to fully recharge.  Repeatedly doing this will dramatically shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully charge.   The main thing to remember with this suggestion is…make sure you fully charge your car battery at least once a week since it’ll greatly increase the life span 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: Check your car battery’s water level.   Most car batteries indicate whether there is a need for water.   So check the car battery water level indicator regularly and when water is required, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your car 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 volatile.

  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 have recommended in this guide but your car batteries are dying early, you will want to look at your car’s alternator (or get a mechanic to check it).
