Your car battery should last about 3 to 5 years…

But many men and women find that they have to change 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 tricks to maximize the lifespan of your car’s 12 volt battery.

The tips we will teach you in this article will be easy to do…and anybody will have the ability 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’s completely independent of how often the battery has been charged or discharged.

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

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

Rather, they die early due to poor maintenance and care…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 stage, which we seek 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 nevertheless 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 car for work).

8 Simple Tips To Prolong The Life Of Your Car’s Lead Acid Battery

Tip 1: Do a monthly review of the battery terminals to make sure they’re clean and corrosion free.   One of the first problems most people have with their car battery is the build-up of corrosion around the terminals.   Corrosion destroys the connection between the battery and the car and several batteries are replaced due to too much corrosive build up.   But often times, this is readily treated simply by 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 in the DIY anti-corrosion paste will eat the rust away.   After the corrosion is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture.  Make certain to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

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

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

Instead, car batteries are meant 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 greatly shorten it’s lifespan if it’s 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 secure 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 whilst creating a security risk.   The same could happen when you have bad battery cables (or they are not connected properly).  So check your cables and make sure they have a secure connection as well.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car battery from big changes in temperature will help maximize 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 does not 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 match 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 automobile 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 car is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the car computers.   This is why people come home from long holidays and find their car battery dead.   But to avoid 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 car is not being used.   They do this by providing enough electricity for the car accessories and car computer, so that they do not always draw current from the car battery when the car is off.   They’re also helpful 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 can 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 suggestion 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 using a charger, interchanging batteries…or just going on a car ride long enough to recharge the battery.

Tip 6: Assess your car battery’s water level.   Most car batteries indicate if there’s 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 is significant, ONLY use distilled water to refill your vehicle battery).

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

  1. It can be explosive.

Tip 8: Assess your vehicle’s alternator.   If you are doing everything we have recommended in this article but your automobile batteries are still dying early, you’ll 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.
