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

But lots of 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 give you 8 easy tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this article will be easy to do…and anyone will have the ability 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’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 1 day.

This set lifespan is known as 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.

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

Rather, they die early because of 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 has to be used lightly.

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

  • 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 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 not able to start your car for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they are clean and rust 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 many batteries are replaced due to a lot of corrosive build up.   But often times, this is easily treated simply by 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 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.  Make certain to allow it to 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 to the car ignition and driving the vehicle.   When the car 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’re just 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.

Rather, 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 as a battery which powers electronics, instead of a battery that just gives you a burst of power for ignition, will damage the battery and greatly 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 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 damage your car while creating a security risk.   The same could happen if 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.

Protecting your car battery from big 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 doesn’t have one, you can easily install one yourself.   Just make sure 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 put in your car model and year, and it will 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 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 vehicle is off.  That happens because current is drawn from the battery by car accessories (radio, lights, etc.) or even the car computers.   This is why folks come home from long holidays and find 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 in use.   They do this by providing enough electricity for the car accessories and car computer, so 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 some time.  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 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 you 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 because it’ll greatly increase the life 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 vehicle battery’s water level.   Most car batteries indicate whether there’s a need for water.   So check the vehicle battery water level indicator frequently and when water is required, 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 oxygen and hydrogen gases when they’re overcharged.

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