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

Your car battery should last about 3 to 5 years…

But many people find that they have to modify their car battery every 1 to 2 years.

Why is this?

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 prevent this from happening.

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

The tips we will teach you in this article 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’s 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 one day.

This set lifespan is known as the battery’s”Calendar Life” and it is completely independent of how many times the battery has been charged or discharged.

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

Rather, they die early due to poor maintenance and care…that you can do something about.

Lead acid batteries are the oldest, most reliable, and most widely used type 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 gently.

  • Peak is the perfect performance phase, which we attempt to keep 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 may either recondition the battery or keep a close eye on it and try to replace it before a problem arises (like being unable to begin your car for work).

8 Simple Tips To Prolong The Life Of Your Car’s Lead Acid Battery

Tip 1: Do a monthly review of the battery terminals to make sure they are clean and corrosion 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 several batteries are replaced because of too much corrosive build up.   But often times, this can be easily treated simply by pouring a small quantity of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) over the corroded areas. 

The acidity in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the rust away.  

Tip 2: Don’t operate any car accessories (radio, lights, or electronics) before turning to the vehicle 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 isn’t on, and you’re using the car’s electronics, you’re just relying on the car battery to power those electronics. 

This is detrimental to the car battery because car batteries are not meant for this type of use.

Instead, car batteries are supposed to provide a sudden burst of power for ignition.  They’re not made to offer prolonged power for electronics and other devices (that is what a deep cycle lead acid battery could be for).   Using your car battery as a battery which powers electronics, instead of a battery that just provides you a burst of electricity for ignition, will damage the battery and greatly shorten it’s lifespan if it is 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 good battery cables.   The battery needs 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 while creating a safety risk.   The same could happen if you have awful battery cables (or they are not connected correctly ).  So check your cables and be sure they have a secure connection also.

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 insulation kit.   Newer model cars already have these kits installed typically.  But if your car does not 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 site where you can put in your car model and year, and it will tell you if your battery will fit their kit — such as here (top of page).   These protective battery sleeves are usually made of plastic or an acid resistant, thermal resistant material.   These car 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.  This 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 vacations and locate their car battery dead.   But to prevent this, you can use either a car battery charger or a solar battery charger. 

Car battery chargers (solar or regular ) will keep the optimum charge level of your car battery when the car is not being used.   They do this by providing enough power for your car accessories and car computer, so that they don’t always draw current from the vehicle battery when the car is off.   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 this 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 tip is…make sure you fully charge your car battery at least once a week because it’ll greatly increase the life span 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 if there is a demand for water.   So check the vehicle battery water level indicator regularly and when water is required, refill the battery with distilled water (and that is significant, ONLY use distilled water to refill your car battery).

Lead-acid batteries release hydrogen and oxygen gases when they’re overcharged.  

  1. It can be explosive.

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

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