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

But lots of people 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?

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 easy 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 be able 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 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 1 day.

This set lifespan is known as the battery’s”Calendar Life” and it is 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 due to poor maintenance and care…which you can do something about.

Lead acid batteries are the earliest, most reliable, and most widely used form of rechargeable battery in the world.

  • Formatting is when the battery is new and has to be used gently.

  • Peak is the perfect performance stage, which we seek 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 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 car for work).

Tip 1: Do a monthly review of the battery terminals to make sure they’re clean and corrosion 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 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) over the corroded areas. 

The acid in the Cola or the alkaline properties in the DIY anti-corrosion paste will eat the corrosion away.   After the rust is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture.  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 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 just relying on the car battery to power those electronic equipment. 

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

Instead, car batteries are meant to offer 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 could be for).   Using your car battery as a battery which powers electronics, instead of a battery that just provides you a burst of electricity 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 vehicle 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’ll be impaired and could short circuit.   This will ruin the battery — and even cause damage to your car whilst creating a security risk.   The same could happen if you have bad battery cables (or they are not connected correctly ).  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 maximize 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 doesn’t have one, you can easily install 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 car battery insulation kits will insulate your battery and protect it while still allowing appropriate ventilation.

Tip 5: Fully control 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.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the car computers.   This is why folks come home from long vacations and find their car battery dead.  

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the vehicle is not in use.   They do this by providing enough electricity for your car accessories and car computer, so they do not always draw current from the car battery when the car is off.   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 shorten 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 since it’ll greatly increase the life span 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: Assess your vehicle battery’s water level.   Most car batteries indicate if there is 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).

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

  1. It can be explosive.

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

Tip 8: Check your car’s alternator.   If you are doing everything we have recommended in this article but your automobile batteries are dying early, you will want to look at your vehicle’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.
