Your car battery should last about 3 to 5 years…

But lots of men and women 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?

We’ll show you why automobile batteries die early…and what you can do to keep this from happening.

We’ll also give you 8 simple tips and techniques 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 have the ability to perform these (even if you know nothing about cars or car batteries).

So let’s get started! …

First, You Should 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 one day.

This set lifespan is called 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 maintenance…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 oldest, most dependable, 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 stage, which we attempt to maintain for as long as you can.

  • Decline is a slow process, but one which slowly ends in the conclusion 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 until a problem arises (like being unable to begin 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’re clean and rust free.   One of the initial 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 many batteries are replaced due to a lot of corrosive build up.   But often times, this can be readily treated by simply pouring a small quantity 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 at the DIY anti-corrosion paste will consume the corrosion away.   Be sure 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 (radio, lights, or electronics) before turning to the vehicle ignition and driving the vehicle.   When the car is on, the auto 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’re simply relying on the car battery to power those electronics. 

This is damaging to the car battery because car batteries are not meant for this type of use.

Rather, car batteries are meant 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, rather than a battery that just provides you a burst of power for ignition, will damage the battery and significantly shorten it’s lifespan if it’s 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 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 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 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 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 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 typically made from plastic or an acid resistant, thermal resistant material.   These automobile 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 car is off.  This happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the automobile computers.   This is why people come home from long vacations and find their car battery dead.  

Car battery chargers (solar or regular ) will keep the optimum charge level of your car battery when the car is not in use.   They do it by providing enough power for your car accessories and car computer, so that they don’t 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 chance to fully recharge.  Repeatedly doing so 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 because 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 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 is important, ONLY use distilled water to refill your vehicle battery).

Tip 7: Do NOT overcharge your car battery.   Never 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.

Tip 8: Assess your vehicle’s alternator.   If you are doing everything we’ve 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).
