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 modify their car battery every 1 to 2 years.

Why is this?

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

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

We’ll show you why car batteries die early…and what you can do to keep 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 guide will be easy to do…and anybody will be able to perform these (even if you know nothing about cars or car batteries).

So let’s begin! …

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 1 day.

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

Once 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 care…which 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 reliable, and most widely used type of rechargeable battery in the world.

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

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

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

Batteries in decline can nevertheless 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 start 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 rust around the terminals.   Corrosion destroys the connection between the battery and the vehicle and several batteries are replaced due to a lot of corrosive build up.   But often times, this is readily treated by simply 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 acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the rust away.   Be sure to let it 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 to 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 isn’t on, and you’re using the car’s electronics, you’re simply relying on the car battery to power those electronics. 

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

Instead, car batteries are supposed to offer a sudden burst of electricity 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 gives you a burst of electricity for ignition, will damage the battery and significantly shorten it’s lifespan if it is 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 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 correctly ).  So check your cables and make sure they have a secure connection as well.

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 insulation kit.   Newer model cars currently have these kits installed typically.  But if your car does not have one, you can easily set up one yourself.   Just make sure 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 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 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 charge 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.  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 find their car battery dead.  

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the car is not in use.   They do it by providing enough power for the car accessories and car computer, so that they don’t 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 opportunity to fully recharge.  Repeatedly doing so 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 most important thing to remember with this suggestion is…make sure you fully charge your car battery at least once a week since it will 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 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 oxygen and hydrogen gases when they are overcharged.   This causes two problems:

  1. It can be explosive.

Tip 8: Check your car’s alternator.   If you’re doing everything we have recommended in this guide but your automobile batteries are dying early, you will want to look at your vehicle’s alternator (or find 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.
