Your car battery should last about 3 to 5 years…

But many men and women find that they need to change their car battery every 1 to 2 years.

And what can you do to prolong your vehicle’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 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 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 care for 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 many times the battery has been charged or discharged.

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

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

A Little Background About Lead Acid Batteries Before Our 8 Battery Tips and Tricks…

Lead acid batteries are the oldest, most reliable, and most widely used form 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 ideal performance stage, which we seek to keep for as long as possible.

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

Batteries in decline can nevertheless 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 until a problem arises (like being not able to begin your car for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they’re clean and rust free.   One of the initial 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 due to a lot of corrosive build up.   But often times, this is readily treated by simply 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 at the DIY anti-corrosion paste will consume the corrosion away.  

Tip 2: Do not operate any car accessories (radio, lights, or electronics) before turning to the car 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 is not on, and you are using the car’s electronics, you’re simply relying on the car battery to power those electronics. 

This is damaging to the car battery because automobile batteries are not meant for this type of use.

Instead, car batteries are supposed 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 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’s 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 secure 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 could short circuit.   This will ruin the battery — and even damage your car while creating a security 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 also.

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 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 usually made from 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 shut-off 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 (radio, lights, etc.) or the car computers.   This is the reason why folks 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 keep the optimum charge level of your car battery when the car is not in use.   They do it by providing enough power for your car accessories and car computer, so they do not 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 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 most important 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 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 if there is a need for water.   So check the car battery water level indicator regularly and if water is required, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your vehicle battery).

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

  1. It can be explosive.

Tip 8: Check your car’s alternator.   If you are doing everything we’ve recommended in this article but your car batteries are dying early, you’ll want to look at your car’s alternator (or find a mechanic to check it).
