But many people find that they need 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?

Well… That’s what we’ll discuss in this article.

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

We’ll also offer you 8 simple tips and tricks to maximize the lifespan of your car’s 12 volt battery.

The tips we’ll teach you in this article will be easy to do…and anybody will have the ability to perform 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’s completely independent of how many times the battery has been 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”…

Rather, 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 oldest, 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 lightly.

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

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

Batteries in decline can nevertheless 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).

Tip 1: Do a monthly review of the battery terminals to make sure they’re 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 many batteries are replaced because of a lot of corrosive build up.   But often times, this is easily treated simply by 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 acidity in the Cola or the alkaline properties at the DIY anti-corrosion paste will consume the corrosion away.   After the rust is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture.  Make certain to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Do not run any car accessories (lights, radio, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the car is on, the car alternator generates electricity and charges the car battery after the battery has a voltage drop.   But if the car isn’t on, and you’re 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 are not meant for this type of use.

Rather, car batteries are meant to provide 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 that powers electronics, rather than a battery that just provides you a burst of electricity for ignition, will damage the battery and greatly shorten it’s lifespan if it’s repeatedly utilized 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 wires.   The battery has to be secured at all times.  If a battery is jostling around it’ll be impaired and could 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.

Tip 4: Insulate your car battery from extreme changes in temperature.  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 currently have these kits installed typically.  But if your car does not have one, you can easily install 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 website where you can put 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 of plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and guard it while still allowing appropriate ventilation.

Tip 5: Fully control 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 car computers.   This is the reason why people come home from long vacations and locate their car battery dead.   But to avoid this, you can use either a car battery charger or a solar battery charger. 

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the car is not being used.   They do it by providing enough electricity for the car accessories and car computer, so they don’t continuously draw current from the vehicle 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 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 one 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 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: Check your car 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 when water is needed, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your car battery).

Never 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 — that shortens its lifespan

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