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

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?

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 prevent this from happening.

We’ll also offer you 8 easy tips and techniques to maximize the lifespan 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 get started! …

First, You Should Know That Every Car Battery’s 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 known as the battery’s”Calendar Life” and it’s completely independent of how many times the battery was 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 complete”Calendar Life”…

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

Lead acid batteries are the earliest, 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 perfect performance phase, which we attempt to keep 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 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 until a problem arises (like being unable to begin your vehicle for work).

Tip 1: Do a monthly review of the battery terminals to be certain they’re clean and corrosion free.   One of the initial 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 many batteries are replaced due to a lot of corrosive build up.   But often times, this is easily treated simply by pouring a small amount of Cola or a DIY anti-corrosion paste (one part water to three parts baking soda) over the corroded areas. 

The acidity in the Cola or the alkaline properties in the DIY anti-corrosion paste will consume the corrosion away.   After the corrosion is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture.  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 (radio, lights, or electronics) before turning on the vehicle 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 is not on, and you’re using the car’s electronics, you’re 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 meant to offer a sudden burst of power for ignition.  They’re not made to provide prolonged power for electronics and other devices (that’s what a deep cycle lead acid battery would be for).   Using your car battery as a battery which powers electronics, instead of a battery that just gives you a burst of power for ignition, will damage the battery and greatly shorten it’s lifespan if it is repeatedly utilized in this fashion.   So avoid operating any car accessories or electronics while the vehicle is off.

Tip 3: Make sure the car battery is safe and has good battery wires.   The battery has to be secured at all times.  If a battery is jostling around it will be impaired and might short circuit.   This will ruin the battery — and even damage your car while creating a security risk.   The same could happen if you have bad battery cables (or they are not connected correctly ).  So check your cables and make sure they have a secure connection also.

Protecting your car 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 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’ll tell you if your battery will fit their kit — like here (top of page).   These protective battery sleeves are typically made of plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and protect it while still allowing appropriate 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.  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 vacations and locate their car battery dead.  

Car battery chargers (solar or regular ) will maintain the optimum charge level of your car battery when the car is not being used.   They do it by providing enough electricity for the car accessories and car computer, so that they don’t always draw current from the car battery when the vehicle 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 useful if you go on plenty of short car trips (like to work and back each day) and never give your battery a chance to fully recharge.  Repeatedly doing this can 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 suggestion is…make sure you fully charge your car battery at least once a week because 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 car battery’s water level.   Most car batteries indicate whether there’s a need for water.   So check the car battery water level indicator regularly and when water is required, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your vehicle battery).

Tip 7: Do NOT overcharge your car battery.   Lead-acid batteries release hydrogen and oxygen gases when they’re 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’ve recommended in this guide but your automobile batteries are dying early, you will want to look at 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.
