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

But many people find that they need to modify their car battery every 1 to 2 years.

And what can you do to prolong your car’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 easy tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we will teach you in this guide will be simple to do…and anybody 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 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’s completely independent of how many times the battery was charged or discharged.

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

Instead, 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 oldest, most dependable, and most widely used type of rechargeable battery in the world.

Lead Acid Batteries have three life phases — formatting, peak, and decline.

  • Formatting is when the battery is new and needs to be used lightly.

  • Peak is the perfect performance stage, which we attempt to maintain for as long as possible.

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

Batteries in decline can still 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 car for work).

Tip 1: Do a monthly review of the battery terminals to be certain they are clean and rust 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 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) within the corroded areas. 

The acidity in the Cola or the alkaline properties at the DIY anti-corrosion paste will consume the rust away.  

Tip 2: Do not operate any car accessories (lights, radio, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the vehicle 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 are using the car’s electronics, you’re just relying on the car battery to power those electronic equipment. 

This is detrimental to the car battery because automobile batteries are not meant for this sort 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’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 power for ignition, will damage the battery and significantly shorten it’s lifespan if it is repeatedly utilized in this fashion.   So avoid operating any automobile accessories or electronics while the car is off.

Tip 3: Make sure the car battery is safe 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 may ruin the battery and even damage your car whilst creating a security risk.   The same could happen if you have awful battery cables (or they are not connected properly).  So check your cables and be 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 fits 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 fit their kit — like 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 appropriate ventilation.

Tip 5: Fully charge 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 vehicle is off.  This happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the automobile 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 it by providing enough power for your car accessories and car computer, so that they do not always draw current from the car 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 will dramatically enhance 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 will greatly increase the life of your battery.  Do this with 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 demand for water.   So check the vehicle battery water level indicator frequently and if water is needed, refill the battery with distilled water (and that’s significant, 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.  

  1. It can be volatile.

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

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