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

But lots of people find that they have to change their car battery every 1 to 2 years.

Why is this?

And what can you do to prolong your car’s battery life?

Well… That’s what we’ll discuss in this report.

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 simple tips and tricks to maximize the life span of your car’s 12 volt battery.

The tips we will teach you in this article will be simple to do…and anyone 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 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 called the battery’s”Calendar Life” and it is completely independent of how many times the battery was charged or discharged.

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

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

Lead acid batteries are the oldest, most reliable, 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 perfect performance stage, which we attempt to maintain for as long as you can.

  • Decline is a slow process, but one which gradually ends in the termination of the battery.

Batteries in decline can still be used for quite some time, 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 start your vehicle for work).

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 car and several batteries are replaced due to a lot of corrosive build up.   But often times, this can be readily treated by simply pouring a small amount of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) within the corroded areas. 

The acid in the Cola or the alkaline properties in the DIY anti-corrosion paste will consume the corrosion away.  

Tip 2: Do not run any car accessories (lights, radio, or electronics) before turning on the vehicle ignition and driving the car.   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 are using the car’s electronics, you are just 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.

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

Tip 3: Make sure the car battery is secure and has good battery wires.   The battery has to be secured at all times.  If a battery is jostling around it will be impaired and could short circuit.   This may ruin the battery — and even damage 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 big 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 does not have one, you can easily set up 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 website where you can place 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 typically made of plastic or an acid resistant, thermal resistant material.   These car battery insulation kits will insulate your battery and guard it while still allowing proper ventilation.

Tip 5: Fully control 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 vehicle is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the automobile computers.   This is the reason why people come home from long holidays and locate their car battery dead.  

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the car is not in use.   They do it by providing enough power for the car accessories and car computer, so that they don’t continuously 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 daily ) and never give your battery a chance to fully recharge.  Repeatedly doing so can 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 suggestion is…be sure you fully charge your car battery at least once a week since 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: Check your car battery’s water level.   Most car batteries indicate if there is a need for water.   So check the car 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 car battery).

Never overcharge your car battery. Lead-acid batteries release hydrogen and oxygen gases when they are overcharged.   This causes two problems:

  1. It can be volatile.

Tip 8: Assess your vehicle’s alternator.   If you are doing everything we have recommended in this article but your automobile batteries are still dying early, you will 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.
