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

But lots of men and women find that they need to modify their car battery every 1 to 2 years.

Why is this?

And what can you do to prolong your vehicle’s battery life?

Well… That’s what we’ll discuss in this article.

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

We’ll also give you 8 simple 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 anybody will be able 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 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.

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

Rather, they die early due to poor maintenance and maintenance…that you can do something about.

Lead acid batteries are the oldest, 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 lightly.

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

  • 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 some time, 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 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’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 is 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.   Be sure to let it 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 car ignition and driving the car.   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 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 automobile batteries are not meant for this sort of use.

Instead, car batteries are supposed 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 could be for).   Using your car battery as a battery that powers electronics, instead of a battery that just gives you a burst of electricity for ignition, will damage the battery and greatly shorten it’s lifespan if it is 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 safe and has great battery wires.   The battery needs 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 damage your car whilst creating a security risk.   The same could happen if you have awful battery cables (or they are not connected correctly ).  So check your cables and be sure they have a secure connection also.

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 currently 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 website 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 of plastic or an acid resistant, thermal resistant material.   These car battery insulation kits will insulate your battery and guard it while still allowing appropriate 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 the reason why people come home from long holidays 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 this by providing enough power for the car accessories and car computer, so they do not always draw current from the car battery when the car is off.   As you can imagine, these chargers are extremely useful…especially if you go on a trip or leave your car unused for a while.  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 you at home to fully charge.   The most important thing to remember with this tip is…make sure you fully charge your car battery at least once a week because it’ll greatly increase the life span 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 car 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).

Never overcharge your car battery. Lead-acid batteries release hydrogen and oxygen gases when they’re overcharged.  

  1. It can be volatile.

Tip 8: Check your car’s alternator.   If you are doing everything we have recommended in this guide but your automobile batteries are still dying early, you will want to check 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.
