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

Your car battery should last about 3 to 5 years…

But lots of 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 car’s battery life?

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

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

The tips we’ll 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 get started! …

First, You Should 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 one day.

This set lifespan is called the battery’s”Calendar Life” and it is completely independent of how many times the battery was charged or discharged.

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

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

Rather, they die early because of 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 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 has to be used gently.

  • Peak is the perfect performance phase, which we seek to maintain for as long as you can.

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

Batteries in decline can still be used for quite some time, but have to 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 unable 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 inspection of the battery terminals to be certain they’re clean and corrosion 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 vehicle and many batteries are replaced due to too much corrosive build up.   But often times, this can be readily treated by simply pouring a small quantity 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 in the DIY anti-corrosion paste will eat the corrosion away.  

Tip 2: Do not run 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 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 detrimental to the car battery because car batteries are not meant for this type of use.

Rather, car batteries are supposed to provide a sudden burst of power for ignition.  They’re not made to provide prolonged power for electronics and other devices (that is 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 significantly shorten it’s lifespan if it is 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 great 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 while creating a security risk.   The same could happen if you have awful battery cables (or they are not connected correctly ).  So check your cables and be sure they have a secure connection also.

Protecting your vehicle battery from big 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 does not 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 website where you can place 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 of 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 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 car computers.   This is the reason why folks come home from long holidays and locate 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 being used.   They do this by providing enough electricity for the car accessories and car computer, so 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 chance to fully recharge.  Repeatedly doing this 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 main 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 span 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’s a need for water.   So check the car battery water level indicator frequently and if water is needed, refill the battery with distilled water (and that is significant, ONLY use distilled water to refill your car battery).

Lead-acid batteries release hydrogen and oxygen gases when they are overcharged.   This causes two problems:

  1. It can be explosive.

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