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 vehicle’s battery life?

We’ll show you why automobile batteries die early…and what you can do to prevent this from happening.

We’ll also give you 8 simple tips and tricks to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this article will be simple to do…and anyone will have the ability to do 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 (but most people kill their battery well before it’s time)

Even if you care for your car battery perfectly…it will still die one 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.

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

Instead, 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 dependable, 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 needs to be used gently.

  • Peak is the ideal performance stage, which we seek 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 have to 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 vehicle 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 be certain they’re 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 because of 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 consume the corrosion away.   Make certain to allow it to dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Don’t operate any car accessories (radio, lights, or electronics) before turning on the vehicle ignition and driving the car.   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 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 type of use.

Rather, car batteries are meant to provide a sudden burst of power for ignition.  They’re not made to provide 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 provides you a burst of power for ignition, will damage the battery and greatly shorten it’s lifespan if it is repeatedly utilized in this fashion.   So avoid operating any automobile accessories or electronics while the car is off.

Tip 3: Make sure the car battery is secure and has great battery cables.   The battery has 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 cause damage to your car while creating a safety risk.   The same could happen if you have awful battery cables (or they’re not connected properly).  So check your cables and make 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 insulating material.   Newer model cars currently 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 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 appropriate 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 car computers.   This is why people 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 (solar or regular ) will maintain the optimum charge level of your car battery when the car is not being used.   They do this by providing enough electricity for the car accessories and car computer, so they do not always draw current from the car 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 helpful if you go on plenty 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 one at home to fully control.   The main thing to remember with this tip is…be 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 with a charger, interchanging batteries…or just going on a car ride long enough to recharge the battery.

Tip 6: Assess your car battery’s water level.   Most car batteries indicate whether there is a demand for water.   So check the vehicle battery water level indicator frequently and if water is required, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your vehicle battery).

Tip 7: Do NOT overcharge 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.

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