Your car battery should last about 3 to 5 years…

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 car batteries die early…and what you can do to prevent this from happening.

We’ll also give you 8 simple 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 easy to do…and anybody will have the ability to perform these (even if you know nothing about cars or car batteries).

So let’s begin! …

First, You Ought to Know That Every Car Battery 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 1 day.

This set lifespan is known as 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 full”Calendar Life”…

Instead, they die early because of poor maintenance and maintenance…that you can do something about.

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

Lead Acid Batteries have three life phases — formatting, peak, and decline.

  • Formatting is when the battery is new and needs to be used gently.

  • Peak is the perfect performance stage, which we seek to keep for as long as possible.

  • Decline is a slow process, but one that slowly ends in the termination of the battery.

Batteries in decline can still be used for quite some time, but must be watched.

Around this time, you can either recondition the battery or keep a close eye on it and try to replace it before a problem arises (like being not able to start your vehicle for work).

Tip 1: Do a monthly inspection 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 corrosion around the terminals.   Corrosion destroys the connection between the battery and the car and many batteries are replaced because of a lot of corrosive build up.   But often times, this can be readily 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 acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will consume the rust away.  

Tip 2: Do not operate any car accessories (radio, lights, or electronics) before turning to the vehicle ignition and driving the vehicle.   When the vehicle is on, the car 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 damaging to the car battery because car batteries aren’t meant for this type of use.

Rather, car batteries are supposed to offer a sudden burst of electricity 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, rather than a battery that just provides you a burst of electricity for ignition, will damage the battery and significantly shorten it’s lifespan if it is repeatedly utilized in this fashion.   So avoid operating any automobile accessories or electronics while the car 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’ll be impaired and might short circuit.   This may ruin the battery and even cause damage to your car whilst creating a safety risk.   The same could happen when you have awful battery cables (or they are not connected properly).  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 does not have one, you can easily set up 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 place 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 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 vehicle is off.  This happens because current is drawn from the battery by car accessories (radio, lights, etc.) or the automobile computers.   This is the reason why people come home from long vacations and locate their car battery dead.   But to avoid this, you can use either a car battery charger or a solar battery charger. 

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 it by providing enough power for your car accessories and car computer, so that they don’t continuously draw current from the vehicle 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 chance to fully recharge.  Repeatedly doing so can dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully charge.   The most important thing to remember with this suggestion is…make sure you fully charge your car battery at least once a week because it’ll greatly increase the life 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 whether there is a demand for water.   So check the car battery water level indicator regularly and if water is required, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your car battery).

Tip 7: Do NOT overcharge your car battery.   Lead-acid batteries release oxygen and hydrogen gases when they’re overcharged.  

  1. It can be explosive.

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