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

But lots of 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 car’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 simple 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 anybody will have the ability 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 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 many times the battery has been charged or discharged.

Once a battery reaches the end of its”Calendar Life” it will become unusable.

But 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.

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

Lead acid batteries are the earliest, most reliable, and most widely used form 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 gently.

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

  • Decline is a slow process, but one which gradually 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 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 vehicle for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they’re clean and corrosion free.   One of the first 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 several batteries are replaced because of too much corrosive build up.   But often times, this is readily treated by simply 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 acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will consume the corrosion away.  

Tip 2: Don’t run any car accessories (lights, radio, or electronics) before turning to the car ignition and driving the vehicle.   When the vehicle 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’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.

Rather, car batteries are meant to offer a sudden burst of power for ignition.  They are not made to offer 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 which 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’s repeatedly used in this fashion.   So avoid operating any car accessories or electronics while the vehicle is off.

Tip 3: Make sure the car battery is safe and has good battery cables.   The battery has to be secured at all times.  If a battery is jostling around it’ll be impaired and might 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’re not connected properly).  So check your cables and make sure they have a secure connection as well.

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 insulation kit.   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 fits 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 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 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 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 (radio, lights, etc.) or the automobile computers.   This is why folks come home from long vacations and find their car battery dead.  

Car battery chargers (regular or solar) will keep the optimum charge level of your car battery when the vehicle is not being used.   They do this by providing enough power for the car accessories and car computer, so that they don’t continuously 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 helpful if you go on plenty of short car trips (like to work and back each day) and never give your battery a chance to fully recharge.  Repeatedly doing this can 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…be sure you fully charge your car battery at least once a week since it will greatly increase the life span of your battery.  Do this using a charger, interchanging batteries…or simply 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 is a demand for water.   So check the car battery water level indicator regularly 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 are overcharged.

Tip 8: Assess your vehicle’s alternator.   If you’re doing everything we have recommended in this article but your car batteries are still dying early, you will want to check your vehicle’s alternator (or find a mechanic to check it).
