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 easy 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 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.

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

However, 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.

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

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

  • Peak is the ideal performance phase, which we seek to maintain for as long as possible.

  • Decline is a slow process, but one which 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 may 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 begin your vehicle for work).

Tip 1: Do a monthly review of the battery terminals to be certain they’re 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 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 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 consume the corrosion away.   Be sure to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Do not run any car accessories (lights, radio, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the car is on, the auto alternator generates electricity and charges the car battery after the battery has a voltage drop.   But if the car isn’t on, and you are using the car’s electronics, you are simply relying on the car battery to power those electronic equipment. 

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

Instead, car batteries are supposed to offer 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 could be for).   Using your car battery for a battery which powers electronics, rather than a battery that just gives 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 automobile 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 could short circuit.   This will ruin the battery and even cause damage to your car while creating a security risk.   The same could happen if you have bad battery cables (or they’re not connected correctly ).  So check your cables and make sure they have a secure connection as well.

Protecting your vehicle 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 fit their kit — such as here (top of page).   These protective battery sleeves are usually made of plastic or an acid resistant, thermal resistant material.   These car battery insulation kits will insulate your battery and protect it while still allowing appropriate 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 car is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the automobile computers.   This is the reason why people come home from long holidays and locate their car battery dead.  

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the vehicle is not in use.   They do this by providing enough electricity for the car accessories and car computer, so that they do not continuously draw current from the car battery when the vehicle is off.   As you can imagine, these chargers are very useful…especially if you go on a trip or leave your car unused for a while.  They’re also useful if you go on a lot of short car trips (like to work and back daily ) 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 main thing to remember with this suggestion is…be sure you fully charge your car battery at least once a week since 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: Assess your vehicle battery’s water level.   Most car batteries indicate whether there is a demand for water.   So check the vehicle battery water level indicator regularly and if water is needed, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your vehicle battery).

Lead-acid batteries release oxygen and hydrogen gases when they are overcharged.

Tip 8: Check your vehicle’s alternator.   If you’re doing everything we have recommended in this article but your car batteries are dying early, you will 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.
