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.

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 car batteries die early…and what you can do to prevent this from happening.

We’ll also give you 8 simple tips and techniques 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 do 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 known as the battery’s”Calendar Life” and it’s completely independent of how often the battery was charged or discharged.

Once a battery reaches the end of its”Calendar Life” it will become unusable.

But most car batteries never make it their complete”Calendar Life”…

Rather, they die early because of poor maintenance and maintenance…which you can do something about.

Lead acid batteries are the earliest, most dependable, and most widely used type of rechargeable battery in the world.

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

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

  • Decline is a slow process, but one which slowly ends in the conclusion 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 until a problem arises (like being not able to begin your vehicle for work).

Tip 1: Do a monthly review of the battery terminals to be certain 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 vehicle and many batteries are replaced due to a lot of corrosive build up.   But often times, this is readily treated by simply pouring a small quantity of Cola or a DIY anti-corrosion glue (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 eat the corrosion away.   Be sure 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 vehicle 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 isn’t on, and you are using the car’s electronics, you are just 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 sort of use.

Rather, car batteries are supposed to offer a sudden burst of electricity for ignition.  They’re 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 for 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 utilized in this fashion.   So avoid operating any car accessories or electronics while the car is off.

Tip 3: Make sure the car battery is secure 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 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 make 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 insulation kit.   Newer model cars already have these kits installed typically.  But if your car doesn’t have one, you can easily set up 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 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 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 shut-off 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 even the automobile computers.   This is the reason why folks come home from long vacations and locate their car battery dead.  

Car battery chargers (regular or solar) will keep the optimum charge level of your car battery when the car is not in use.   They do this by providing enough power for the car accessories and car computer, so that they don’t continuously draw current from the vehicle battery when the vehicle 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 useful if you go on a lot of short car trips (like to work and back daily ) and never give your battery a opportunity to fully recharge.  Repeatedly doing this can dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully control.   The main thing to remember with this suggestion is…be sure you fully charge your car battery at least once a week since 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 car battery’s water level.   Most car batteries indicate whether there’s a demand for water.   So check the vehicle battery water level indicator frequently and when water is required, 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 are overcharged.   This causes two problems:

  1. It can be volatile.

Tip 8: Check your car’s alternator.   If you’re 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).
