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 offer you 8 easy tips and tricks to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this article will be simple to do…and anybody will have the ability 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 (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 is completely independent of how often the battery was charged or discharged.

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.

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 ideal performance stage, which we seek to keep 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 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 unable to begin your vehicle for work).

Tip 1: Do a monthly review 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 rust around the terminals.   Corrosion destroys the connection between the battery and the car and several batteries are replaced due to 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 glue (one part water to three parts baking soda) over the corroded areas. 

The acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat 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 car 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’re just relying on the car battery to power those electronics. 

This is detrimental to the car battery because automobile batteries are not meant for this type of use.

Rather, car batteries are supposed to offer a sudden burst of power for ignition.  They are not made to provide 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 which powers electronics, instead of a battery that just gives you a burst of electricity for ignition, will damage the battery and greatly 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 great battery cables.   The battery needs to be secured at all times.  If a battery is jostling around it will 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 when you have awful battery cables (or they are not connected properly).  So check your cables and be 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 insulating material.   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 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 car 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.  This happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the car computers.   This is the reason why people come home from long holidays and locate their car battery dead.  

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the vehicle is not in use.   They do this by providing enough electricity for the car accessories and car computer, so that they don’t continuously 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 a while.  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 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 most important thing to remember with this tip is…be 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 just going on a car ride long enough to recharge the battery.

Tip 6: Assess your car battery’s water level.   Most car batteries indicate if there is a demand for water.   So check the car battery water level indicator frequently and if water is needed, refill the battery with distilled water (and that’s significant, ONLY use distilled water to refill your car battery).

Never overcharge your car battery. Lead-acid batteries release hydrogen and oxygen gases when they’re overcharged.  

  1. It can be explosive.

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