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

But many people find that they have 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 automobile 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 life span of your car’s 12 volt battery.

The tips we will teach you in this guide will be simple to do…and anyone will be able 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’s 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 known as the battery’s”Calendar Life” and it’s completely independent of how many times the battery was charged or discharged.

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

Rather, they die early due to poor maintenance and maintenance…which you can do something about.

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

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

  • Peak is the ideal performance phase, 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 nevertheless be used for quite a while, but must 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 not able to start 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 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 car and many batteries are replaced due to too much corrosive build up.   But often times, this can be readily treated simply by pouring a small quantity of Cola or a DIY anti-corrosion glue (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 consume the corrosion away.   After the corrosion is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

Tip 2: Do not run any car accessories (lights, radio, or electronics) before turning to the car ignition and driving the vehicle.   When the car 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 automobile batteries aren’t meant for this sort of use.

Instead, car batteries are meant to offer a sudden burst of power for ignition.  They’re not made to provide prolonged power for electronics and other devices (that’s what a deep cycle lead acid battery could 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’s repeatedly used in this fashion.   So avoid operating any car accessories or electronics while the car is off.

Tip 3: Make sure the car battery is safe and has good battery cables.   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 whilst creating a security risk.   The same could happen if you have bad battery cables (or they are not connected correctly ).  So check your cables and make sure they have a secure connection also.

Protecting your car battery from big changes in temperature will help optimize the battery’s lifespan.   To do this you can use a car battery insulation kit.   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 website where you can place in your car model and year, and it’ll tell you if your battery will match their kit — like here (top of page).   These protective battery sleeves are typically 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 interchange batteries if you have to).   Your car battery drains even when the car is off.  This happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the automobile computers.   This is why people come home from long holidays and locate their car battery dead.  

Car battery chargers (regular or solar) will keep the optimum charge level of your car battery when the car is not in use.   They do this by providing enough power for your car accessories and car computer, so that they don’t always draw current from the car battery when the vehicle is off.   As you can imagine, these chargers are extremely useful…especially if you go on a trip or leave your car unused for some time.  They’re also helpful 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 so will dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully charge.   The main 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 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 vehicle battery water level indicator frequently and when 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 hydrogen and oxygen gases when they’re overcharged.  

  1. It can be volatile.

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

Tip 8: Check your vehicle’s alternator.   If you’re doing everything we’ve recommended in this article 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.
