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

But many men and women find that they need to change their car battery every 1 to 2 years.

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 keep this from happening.

We’ll also give you 8 easy 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 anyone will be able to perform these (even if you know nothing about cars or car batteries).

So let’s begin! …

First, You Ought to Know That Every Car Battery Lifespan Has A Limit (but most people kill their battery well before it’s time)

Even if you take care of 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 many times the battery was 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 full”Calendar Life”…

Rather, they die early because of poor maintenance and care…which 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.

  • Formatting is when the battery is new and needs to be used lightly.

  • Peak is the perfect performance stage, which we attempt to maintain 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 a while, but have to be watched.

Around this time, you can 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 inspection of the battery terminals to be certain they’re 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 a lot of corrosive build up.   But often times, this is easily treated by simply pouring a small quantity 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 rust away.   After the corrosion is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

Tip 2: Don’t operate any car accessories (lights, radio, or electronics) before turning on the car ignition and driving the car.   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 is not on, and you’re using the car’s electronics, you are simply relying on the car battery to power those electronics. 

This is detrimental to the car battery because car batteries are not meant for this sort 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’s what a deep cycle lead acid battery could be for).   Using your car battery for 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 used in this fashion.   So avoid operating any automobile accessories or electronics while the car is off.

Tip 3: Make sure the car battery is safe and has great battery wires.   The battery needs to be secured at all times.  If a battery is jostling around it’ll be impaired and might short circuit.   This may 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 are not connected properly).  So check your cables and be sure they have a secure connection also.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car battery from large changes in temperature will help optimize 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 install one yourself.   Just make sure 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 match their kit — like here (top of page).   These protective battery sleeves are typically made from plastic or an acid resistant, thermal resistant material.   These automobile 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 car computers.   This is why people come home from long holidays and find their car battery dead.  

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the car is not in use.   They do this by providing enough power for your car accessories and car computer, so they do not always 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 helpful if you go on a lot of short car trips (like to work and back daily ) and never give your battery a chance to fully recharge.  Repeatedly doing so can dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully charge.   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 will 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’s a demand for water.   So check the car battery water level indicator frequently and when water is required, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your vehicle battery).

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

  1. It can be volatile.

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