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 keep this from happening.

We’ll also offer you 8 simple 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 easy to do…and anybody will be able 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’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’s 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.

But most car batteries never make it their complete”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 lightly.

  • Peak is the ideal performance phase, which we seek to keep for as long as possible.

  • Decline is a slow process, but one that gradually 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 before a problem arises (like being not able to start your vehicle for work).

Tip 1: Do a monthly review 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 several batteries are replaced because of too much corrosive build up.   But often times, this can be 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 in the DIY anti-corrosion paste will consume the corrosion away.  

Tip 2: Don’t operate any car accessories (lights, radio, or electronics) before turning to the vehicle ignition and driving the car.   When the vehicle is on, the auto 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 simply relying on the car battery to power those electronics. 

This is detrimental to the car battery because automobile batteries aren’t meant for this type of use.

Rather, car batteries are meant to provide a sudden burst of electricity for ignition.  They are 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’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 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 will ruin the battery — and even cause damage to your car while creating a security risk.   The same could happen if you have awful battery cables (or they are not connected properly).  So check your cables and be sure they have a secure connection also.

Protecting your vehicle 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 doesn’t 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 site where you can place 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 from plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and protect 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 (lights, radio, etc.) or the car computers.   This is the reason why people come home from long vacations and find their car battery dead.  

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the vehicle is not being used.   They do it by providing enough power for your car accessories and car computer, so that they do not always 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 a while.  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 opportunity 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 control.   The most important thing to remember with this tip is…be sure you fully charge your car battery at least once a week because it will 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: Check your vehicle battery’s water level.   Most car batteries indicate whether there’s a need for water.   So check the car battery water level indicator regularly and if water is required, refill the battery with distilled water (and that’s 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 hydrogen and oxygen gases when they’re overcharged.  

  1. It can be explosive.

Tip 8: Assess your vehicle’s alternator.   If you are doing everything we have recommended in this article but your automobile batteries are dying early, you’ll want to look at your car’s alternator (or find a mechanic to check it).   If your alternator is bad it will results in ineffective recharging of your battery and dramatically shorten your battery’s lifespan.
