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

Your car battery should last about 3 to 5 years…

But lots of men and women 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 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 simple to do…and anybody will be able to do these (even if you know nothing about cars or car batteries).

So let’s begin! …

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 care for your car battery perfectly…it will still die 1 day.

This set lifespan is known as the battery’s”Calendar Life” and it’s 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”…

Instead, they die early because of poor maintenance and maintenance…which 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 dependable, and most widely used form 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 you can.

  • 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 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 before a problem arises (like being not able to begin 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 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 vehicle and several batteries are replaced due to a lot of corrosive build up.   But often times, this can be readily treated simply by pouring a small amount 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 in the DIY anti-corrosion paste will eat the rust away.   After the rust is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

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

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

Instead, car batteries are meant to provide a sudden burst of electricity for ignition.  They are 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 which powers electronics, rather than 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 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 will be impaired and might short circuit.   This may ruin the battery — and even cause damage to your car while creating a safety risk.   The same could happen if you have awful battery cables (or they are not connected correctly ).  So check your cables and make sure they have a secure connection as well.

Protecting your car 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 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 will 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 car 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 car is off.  That happens because current is drawn from the battery by car accessories (radio, lights, etc.) or the automobile computers.   This is 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 (regular or solar) will maintain the optimum charge level of your car battery when the car is not being used.   They do it by providing enough power for your car accessories and car computer, so that they don’t continuously draw current from the car 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 will dramatically shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully control.   The main thing to remember with this tip is…make 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 with a charger, interchanging batteries…or just going on a car ride long enough to recharge the battery.

Tip 6: Assess 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 frequently and if water is required, 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.   Never 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: Check your car’s alternator.   If you are doing everything we’ve recommended in this article but your car batteries are still dying early, you’ll want to check your vehicle’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.
