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

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.

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 keep 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 article will be easy to do…and anyone will have the ability to perform these (even if you know nothing about cars or car batteries).

So let’s begin! …

First, You Should Know That Every Car Battery’s Lifespan Has A Limit (but 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 often the battery has been charged or discharged.

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

Instead, they die early because of poor maintenance and care…which you can do something about.

Lead acid batteries are the earliest, most dependable, 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 attempt to keep for as long as possible.

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

Batteries in decline can nevertheless be used for quite a while, but must 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 begin your vehicle for work).

Tip 1: Do a monthly review of the battery terminals to make sure they’re 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 due to too much corrosive build up.   But often times, this can be easily treated by simply 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 acidity in the Cola or the alkaline properties in the DIY anti-corrosion paste will eat the rust away.  

Tip 2: Don’t operate any car accessories (radio, lights, or electronics) before turning on the car ignition and driving the car.   When the car is on, the car alternator generates electricity and charges the car battery after the battery has a voltage drop.   But if the car is not on, and you’re using the car’s electronics, you’re 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 type of use.

Instead, car batteries are supposed to provide a sudden burst of power for ignition.  They’re not made to offer prolonged power for electronics and other devices (that is what a deep cycle lead acid battery could be for).   Using your car battery for a battery that powers electronics, instead of 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 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 secure and has great battery cables.   The battery needs to be secured at all times.  If a battery is jostling around it will 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 if you have awful battery cables (or they’re not connected properly).  So check your cables and make sure they have a secure connection also.

Protecting your car battery from big changes in temperature will help maximize 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 set up 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 site where you can put in your car model and year, and it’ll 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 proper 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.  This happens because current is drawn from the battery by car accessories (radio, lights, etc.) or even the automobile computers.   This is the reason why people come home from long holidays 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 in use.   They do it by providing enough electricity for the car accessories and car computer, so they do not continuously draw current from the car battery when the vehicle is off.   They’re also helpful if you go on plenty 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 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 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 car battery’s water level.   Most car batteries indicate whether there is a need for water.   So check the car battery water level indicator frequently and if water is required, refill the battery with distilled water (and that is significant, ONLY use distilled water to refill your vehicle battery).

Tip 7: Do NOT overcharge your car battery.   Lead-acid batteries release oxygen and hydrogen gases when they’re overcharged.   This causes two problems:

  1. It can be volatile.

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

Tip 8: Assess your car’s alternator.   If you’re doing everything we have recommended in this guide but your car batteries are dying early, you will want to check 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.
