But lots of men and women find that they need to modify their car battery every 1 to 2 years.

Why is this?

And what can you do to prolong your vehicle’s battery life?

We’ll show you why automobile batteries die early…and what you can do to prevent this from happening.

We’ll also give you 8 easy tips and tricks to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this article will be simple to do…and anyone will be able to do these (even if you know nothing about cars or car batteries).

So let’s get started! …

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 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 is completely independent of how many times the battery was charged or discharged.

But 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.

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

  • Peak is the perfect performance stage, which we attempt to maintain 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 nevertheless be used for quite a while, 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 before a problem arises (like being unable to start your car for work).

Tip 1: Do a monthly review of the battery terminals to make sure 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 several batteries are replaced because of too much corrosive build up.   But often times, this is readily 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 eat the corrosion away.   Make certain to allow it to dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Don’t run any car accessories (radio, lights, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the vehicle is on, the auto 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 are simply relying on the car battery to power those electronics. 

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

Instead, car batteries are supposed to provide a sudden burst of electricity for ignition.  They are 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 that powers electronics, rather than a battery that just gives you a burst of power for ignition, will damage the battery and significantly shorten it’s lifespan if it’s repeatedly used in this fashion.   So avoid operating any automobile 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 may ruin the battery and even cause damage to your car while creating a security risk.   The same could happen when you have awful battery cables (or they’re not connected correctly ).  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 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 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 will tell you if your battery will fit their kit — such as here (top of page).   These protective battery sleeves are typically made from plastic or an acid resistant, thermal resistant material.   These car 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 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 vacations 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 vehicle is not in use.   They do this by providing enough power for your car accessories and car computer, so they do not continuously draw current from the car 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 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 will dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving one at home to fully charge.   The main thing to remember with this tip is…make sure you fully charge your car battery at least once a week since it’ll greatly increase the life of your battery.  Do this using a charger, interchanging batteries…or simply going on a car ride long enough to recharge the battery.

Tip 6: Check 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 needed, refill the battery with distilled water (and that is 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.   This causes two problems:

  1. It can be explosive.

  2. It also breaks down the composition of the water in the battery — which shortens its lifespan

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