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 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 offer you 8 simple tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this article 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 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 is completely independent of how many times the battery was 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 due to poor maintenance and maintenance…which you can do something about.

Lead acid batteries are the oldest, 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 perfect performance phase, which we seek to keep 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 some time, 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 make sure they are 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 too much corrosive build up.   But often times, this is easily treated by simply 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 at the DIY anti-corrosion paste will consume the corrosion away.   After the rust is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture.  Make certain to allow it to 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 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’re 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 are not meant for this sort of use.

Rather, car batteries are supposed to provide a sudden burst of power for ignition.  They’re not made to provide prolonged power for electronics and other devices (that is what a deep cycle lead acid battery could be for).   Using your car battery as a battery which powers electronics, instead of a battery that just provides 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 car accessories or electronics while the car is off.

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

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car battery from big changes in temperature will help optimize the battery’s lifespan.   To do this you can use a car battery insulating material.   Newer model cars already have these kits installed typically.  But if your car doesn’t have one, you can easily install 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 website where you can put in your car model and year, and it will tell you if your battery will match their kit — like 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 protect it while still allowing proper 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 vehicle is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the automobile computers.   This is why people come home from long vacations 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 electricity for the car accessories and car computer, so they do not continuously draw current from the vehicle 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 some time.  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 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…be 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 with 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 if there is a demand for water.   So check the car battery water level indicator regularly and when water is needed, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your car battery).

Tip 7: Do NOT overcharge your car battery.   Lead-acid batteries release hydrogen and oxygen gases when they are overcharged.   This causes two problems:

  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 vehicle’s alternator.   If you’re doing everything we’ve recommended in this article 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.
