Your car battery should last about 3 to 5 years…

But lots of men and women find that they need 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?

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 be able to do 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 (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 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.

After a battery reaches the end of its”Calendar Life” it will become unusable.

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

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

A Little Background About Lead Acid Batteries Before Our 8 Battery Tips and Tricks…

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

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

  • Peak is the ideal performance phase, 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 nevertheless be used for quite a while, 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 until a problem arises (like being not able to start your car for work).

Tip 1: Do a monthly review 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 rust around the terminals.   Corrosion destroys the connection between the battery and the vehicle and many batteries are replaced due to too much corrosive build up.   But often times, this can be readily treated simply by pouring a small quantity of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) within the corroded areas. 

The acidity in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the corrosion away.   After the corrosion is gone, 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: Do not operate any car accessories (lights, radio, or electronics) before turning to the vehicle ignition and driving the vehicle.   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 are just relying on the car battery to power those electronics. 

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

Instead, car batteries are supposed to offer a sudden burst of electricity for ignition.  They’re 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, instead of a battery that just provides you a burst of power for ignition, will damage the battery and significantly 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 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 damage your car whilst creating a security risk.   The same could happen if you have bad battery cables (or they are not connected properly).  So check your cables and be sure they have a secure connection as well.

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 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 site where you can place in your car model and year, and it’ll tell you if your battery will match 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 protect it while still allowing proper ventilation.

Tip 5: Fully charge 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 the reason why folks come home from long holidays and find their car battery dead.   But to prevent this, you can use either a car battery charger or a solar battery charger. 

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the vehicle is not being used.   They do this by providing enough electricity for the car accessories and car computer, so they do not continuously draw current from the vehicle 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 enhance 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 suggestion is…make sure you fully charge your car battery at least once a week because it’ll greatly increase the life span of your battery.  Do this using 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 whether there is a need for water.   So check the vehicle battery water level indicator regularly and if water is needed, refill the battery with distilled water (and that’s significant, ONLY use distilled water to refill your vehicle battery).

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

  1. It can be explosive.

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