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 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 simple 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 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’s Lifespan Has A Limit (however most people kill their battery well before it’s time)

Even if you care for 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 many times the battery was 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 because of poor maintenance and care…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 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 gently.

  • Peak is the perfect performance stage, which we attempt to keep 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 nevertheless be used for quite some time, 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 before a problem arises (like being unable to start your vehicle for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure 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 several batteries are replaced due to a lot of corrosive build up.   But often times, this is readily treated by simply pouring a small amount of Cola or a DIY anti-corrosion glue (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 rust away.  

Tip 2: Do not operate any car accessories (lights, radio, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the vehicle 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 simply relying on the car battery to power those electronic equipment. 

This is damaging to the car battery because automobile batteries are not 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 offer prolonged power for electronics and other devices (that is what a deep cycle lead acid battery could be for).   Using your car battery as 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’s repeatedly utilized in this fashion.   So avoid operating any automobile accessories or electronics while the car is off.

Tip 3: Make sure the car battery is secure and has great battery wires.   The battery has to be secured at all times.  If a battery is jostling around it will be impaired and might short circuit.   This will ruin the battery and even cause damage to your car while creating a security risk.   The same could happen when you have awful battery cables (or they are 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 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 doesn’t have one, you can easily install one yourself.   Just be certain 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’ll tell you if your battery will fit their kit — like here (top of page).   These protective battery sleeves are typically made from plastic or an acid resistant, thermal resistant material.   These car battery insulation kits will insulate your battery and protect 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 car is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the automobile computers.   This is the reason why people come home from long vacations and locate their car battery dead.  

Car battery chargers (solar or regular ) will keep the optimum charge level of your car battery when the car is not in use.   They do it by providing enough power for your car accessories and car computer, so they don’t continuously draw current from the car 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 daily ) and never give your battery a opportunity to fully recharge.  Repeatedly doing this can dramatically shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving one 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 with a charger, interchanging batteries…or just going on a car ride long enough to recharge the battery.

Tip 6: Check your car battery’s water level.   Most car batteries indicate if there’s a need for water.   So check the car 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).

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

  1. It can be explosive.

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