8 Simple Tips & Trick To Extend The Life Of Your Car Battery

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 vehicle’s battery life?

Well… That’s what we’ll discuss in this article.

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 easy tips and techniques to maximize the lifespan of your car’s 12 volt battery.

The tips we will teach you in this guide will be simple to do…and anybody will be able 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’s 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 1 day.

This set lifespan is known as the battery’s”Calendar Life” and it is completely independent of how often the battery was 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 maintenance…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 earliest, 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 has to be used gently.

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

  • Decline is a slow process, but one which gradually ends in the conclusion 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 before a problem arises (like being unable to begin your vehicle for work).

Tip 1: Do a monthly inspection of the battery terminals to be certain they are clean and rust free.   One of the first 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 car and several batteries are replaced due to too much corrosive build up.   But often times, this is easily 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 at the DIY anti-corrosion paste will consume the corrosion away.  

Tip 2: Don’t operate any car accessories (radio, lights, or electronics) before turning on the vehicle ignition and driving the car.   When the vehicle is on, the auto 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’re 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 type of use.

Instead, car batteries are meant to provide a sudden burst of electricity for ignition.  They’re not made to offer prolonged power for electronics and other devices (that’s what a deep cycle lead acid battery would be for).   Using your car battery for a battery which powers electronics, instead of a battery that just provides you a burst of power for ignition, will damage the battery and greatly shorten it’s lifespan if it’s repeatedly used 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 great battery cables.   The battery needs 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 damage your car whilst creating a security risk.   The same could happen if you have bad battery cables (or they’re not connected properly).  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 vehicle 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 doesn’t have one, you can easily install 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 usually made of plastic or an acid resistant, thermal resistant material.   These car battery insulation kits will insulate your battery and guard it while still allowing appropriate ventilation.

Tip 5: Fully charge 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 car is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the car computers.   This is why people come home from long holidays and find their car battery dead.  

Car battery chargers (solar or regular ) will keep the optimum charge level of your car battery when the vehicle is not in use.   They do this by providing enough electricity for the car accessories and car computer, so that they don’t continuously draw current from the car battery when the car is off.   They’re also helpful if you go on a lot of short car trips (like to work and back daily ) and never give your battery a chance to fully recharge.  Repeatedly doing this will dramatically shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully control.   The most important thing to remember with this suggestion is…be 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 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 is a demand for water.   So check the vehicle 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).

Lead-acid batteries release hydrogen and oxygen gases when they are overcharged.  

  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’ve recommended in this article but your automobile batteries are dying early, you will want to check your vehicle’s alternator (or get a mechanic to check it).
