Your car battery should last about 3 to 5 years…

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

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

The tips we will teach you in this guide will be easy 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 (however 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 is completely independent of how often the battery has been charged or discharged.

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

Rather, they die early due to 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 has to be used lightly.

  • 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 gradually ends in the conclusion of the battery.

Batteries in decline can nevertheless be used for quite some time, 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 car 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 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 corrosion around the terminals.   Corrosion destroys the connection between the battery and the vehicle and several batteries are replaced because of too much corrosive build up.   But often times, this can be readily treated simply by pouring a small amount of Cola or a DIY anti-corrosion glue (one part water to three parts baking soda) over the corroded areas. 

The acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the rust away.   Make certain to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Do not run any car accessories (radio, lights, or electronics) before turning on the car ignition and driving the car.   When the vehicle 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 are using the car’s electronics, you are simply relying on the car battery to power those electronic equipment. 

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

Rather, car batteries are meant to offer a sudden burst of power for ignition.  They are not made to provide prolonged power for electronics and other devices (that’s what a deep cycle lead acid battery could be for).   Using your car battery as a battery that 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’s 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 good battery cables.   The battery has 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 whilst creating a safety risk.   The same could happen when you have bad battery cables (or they’re not connected properly).  So check your cables and be sure they have a secure connection also.

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 currently have these kits installed typically.  But if your car does not have one, you can easily set up one yourself.   Just make sure 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 will tell you if your battery will fit their kit — such as here (top of page).   These protective battery sleeves are typically made of plastic or an acid resistant, thermal resistant material.   These automobile 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.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the automobile computers.   This is why folks come home from long vacations and locate 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 keep the optimum charge level of your car battery when the vehicle is not being used.   They do it by providing enough electricity for your car accessories and car computer, so that they don’t always draw current from the car battery when the car is off.   They’re also useful if you go on plenty 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 shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving one 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 since it will greatly increase the life span of your battery.  Do this using a charger, interchanging batteries…or just going on a car ride long enough to recharge the battery.

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

Never overcharge your car battery. Lead-acid batteries release oxygen and hydrogen gases when they’re overcharged.  

  1. It can be explosive.

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