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

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 simple to do…and anyone will have the ability to do these (even if you know nothing about cars or car batteries).

So let’s begin! …

First, You Should 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 one day.

This set lifespan is called the battery’s”Calendar Life” and it is completely independent of how many times the battery has been charged or discharged.

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

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

Rather, they die early because of 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 perfect performance stage, which we seek 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 until a problem arises (like being not able to start your vehicle 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 rust around the terminals.   Corrosion destroys the connection between the battery and the car and many batteries are replaced due to too much corrosive build up.   But often times, this is 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 in the DIY anti-corrosion paste will eat the rust away.   After the corrosion is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

Tip 2: Do not operate any car accessories (lights, radio, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the car is on, the car alternator generates electricity and charges the vehicle battery after the battery has a voltage drop.   But if the car isn’t on, and you’re 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 automobile batteries aren’t meant for this sort of use.

Rather, car batteries are meant to provide 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 would be for).   Using your car battery for a battery that powers electronics, instead of a battery that just provides you a burst of electricity for ignition, will damage the battery and significantly 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 safe and has great battery wires.   The battery needs to be secured at all times.  If a battery is jostling around it will 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 make sure they have a secure connection also.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car battery from large changes in temperature will help optimize 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 doesn’t have one, you can easily install 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 put 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 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 (lights, radio, etc.) or even the car computers.   This is why folks come home from long vacations and locate their car battery dead.   But to prevent this, you can use either a car battery charger or a solar battery charger. 

Car battery chargers (regular or solar) 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 do not always 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 each day) and never give your battery a opportunity to fully recharge.  Repeatedly doing so can dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully charge.   The most important 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 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: Check your vehicle battery’s water level.   Most car batteries indicate if there’s a demand for water.   So check the car battery water level indicator frequently and if water is required, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your car battery).

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

  1. It can be explosive.

Tip 8: Check your car’s alternator.   If you’re 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 find a mechanic to check it).
