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

Your car battery should last about 3 to 5 years…

But many men and women 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 keep 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 guide 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 get started! …

First, You Ought to Know That Every Car Battery 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 1 day.

This set lifespan is called the battery’s”Calendar Life” and it’s completely independent of how often the battery has been charged or discharged.

However, most car batteries never make it their full”Calendar Life”…

Rather, 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 oldest, most dependable, and most widely used form of rechargeable battery in the world.

  • 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 possible.

  • Decline is a slow process, but one that slowly ends in the conclusion 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 until a problem arises (like being unable to start your car for work).

Tip 1: Do a monthly review of the battery terminals to be certain 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 car and several batteries are replaced due to too much corrosive build up.   But often times, this is 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 consume the rust away.   After the corrosion is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture.  Be sure to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Don’t operate any car accessories (lights, radio, or electronics) before turning to the car ignition and driving the vehicle.   When the car is on, the car alternator generates electricity and charges the vehicle battery after the battery has a voltage drop.   But if the car isn’t on, and you’re using the car’s electronics, you’re simply relying on the car battery to power those electronic equipment. 

This is damaging to the car battery because automobile batteries aren’t meant for this type of use.

Instead, car batteries are supposed to provide a sudden burst of electricity for ignition.  They are not made to offer prolonged power for electronics and other devices (that is what a deep cycle lead acid battery would be for).   Using your car battery for a battery which 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 vehicle is off.

Tip 3: Make sure the car battery is secure and has good battery wires.   The battery needs to be secured at all times.  If a battery is jostling around it will be impaired and could short circuit.   This may ruin the battery and even damage your car while creating a security risk.   The same could happen when 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.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your vehicle 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 already 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 website where you can place in your car model and year, and it will tell you if your battery will match their kit — such as here (top of page).   These protective battery sleeves are usually made from 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 interchange batteries if you have to).   Your car battery drains even when the vehicle is off.  This 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 locate their car battery dead.  

Car battery chargers (solar or regular ) 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 your car accessories and car computer, so they do not continuously draw current from the vehicle battery when the vehicle is off.   As you can imagine, these chargers are extremely useful…especially if you go on a trip or leave your car unused for a while.  They’re also helpful 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 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 because 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: Assess your vehicle battery’s water level.   Most car batteries indicate whether there is a demand for water.   So check the vehicle battery water level indicator regularly and when water is needed, refill the battery with distilled water (and that’s 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 volatile.

  2. It also breaks down the composition of the water in the battery — which shortens its lifespan

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