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.

And what can you do to prolong your car’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 easy tips and tricks to maximize the lifespan of your car’s 12 volt battery.

The tips we’ll teach you in this guide will be easy to do…and anyone will have the ability to do 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 care for your car battery perfectly…it will still die one day.

This set lifespan is called the battery’s”Calendar Life” and it is completely independent of how many times the battery has been 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 full”Calendar Life”…

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

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 has to be used gently.

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

  • 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 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 inspection of the battery terminals to be certain they’re 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 is readily treated simply by pouring a small amount of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) over the corroded areas. 

The acid in the Cola or the alkaline properties in 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. 

Tip 2: Do not run any car accessories (radio, lights, or electronics) before turning to the car ignition and driving the vehicle.   When the vehicle is on, the car alternator generates electricity and charges the vehicle battery after the battery has a voltage drop.   But if the car is not on, and you’re using the car’s electronics, you are just relying on the car battery to power those electronics. 

This is damaging to the car battery because automobile batteries are not meant for this sort of use.

Instead, car batteries are supposed to provide a sudden burst of electricity for ignition.  They are not made to provide 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, rather than a battery that just gives you a burst of electricity for ignition, will damage the battery and greatly shorten it’s lifespan if it is repeatedly used in this fashion.   So avoid operating any car accessories or electronics while the vehicle is off.

Tip 3: Make sure the car battery is safe and has good battery wires.   The battery needs to be secured at all times.  If a battery is jostling around it’ll be impaired and could short circuit.   This will ruin the battery and even cause damage to your car whilst creating a safety 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 also.

Tip 4: Insulate your car battery from extreme changes in temperature.  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 already have these kits installed typically.  But if your car doesn’t have one, you can easily install one yourself.   Just be certain it matches 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 usually made of 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 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 (radio, lights, etc.) or the automobile computers.   This is why people come home from long holidays and locate their car battery dead.  

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 it by providing enough power for the car accessories and car computer, so that they don’t always draw current from the car battery when the car is off.   As you can imagine, these chargers are extremely 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 each day) 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 you at home to fully control.   The most important thing to remember with this tip is…make sure you fully charge your car battery at least once a week because it will greatly increase the life of your battery.  Do this with a charger, interchanging batteries…or simply going on a car ride long enough to recharge the battery.

Tip 6: Check your vehicle battery’s water level.   Most car batteries indicate if there’s a demand for water.   So check the car 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 vehicle battery).

Lead-acid batteries release oxygen and hydrogen gases when they are overcharged.   This causes two problems:

  1. It can be volatile.

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

Tip 8: Assess your car’s alternator.   If you are doing everything we’ve recommended in this article but your automobile batteries are dying early, you will want to look at your car’s alternator (or get 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.
