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

Your car battery should last about 3 to 5 years…

But many men and women find that they have to modify 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 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’ll teach you in this guide will be simple to do…and anyone will have the ability 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’s completely independent of how often the battery has been charged or discharged.

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

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

Rather, they die early because of 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 dependable, and most widely used form of rechargeable battery in the world.

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

  • Peak is the ideal performance stage, which we attempt to maintain for as long as possible.

  • Decline is a slow process, but one that 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 until a problem arises (like being unable to begin your vehicle for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they’re clean and corrosion 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 because of too much corrosive build up.   But often times, this is easily treated by simply pouring a small quantity of Cola or a DIY anti-corrosion glue (one part water to three parts baking soda) within the corroded areas. 

The acid in the Cola or the alkaline properties in 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: Do not operate any car accessories (radio, lights, or electronics) before turning to the vehicle ignition and driving the vehicle.   When the car 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’re simply relying on the car battery to power those electronic equipment. 

This is detrimental to the car battery because car batteries are not meant for this type of use.

Rather, car batteries are meant to offer a sudden burst of power for ignition.  They are not made to offer prolonged power for electronics and other devices (that is 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 electricity 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 secure and has great battery cables.   The battery needs 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 while creating a security risk.   The same could happen if 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.

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 set up one yourself.   Just make sure it fits 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’ll tell you if your battery will fit their kit — like here (top of page).   These protective battery sleeves are usually made of plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and guard it while still allowing proper 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 (lights, radio, etc.) or the automobile computers.   This is the reason why folks come home from long holidays and locate 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 keep the optimum charge level of your car battery when the car is not in use.   They do this by providing enough electricity for your car accessories and car computer, so they don’t continuously draw current from the car battery when the car is off.   As you can imagine, these chargers are very 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 daily ) and never give your battery a chance to fully recharge.  Repeatedly doing so can dramatically enhance 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…make sure you fully charge your car battery at least once a week because it will greatly increase the life span of your battery.  Do this with a charger, interchanging batteries…or just 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 need for water.   So check the car battery water level indicator regularly and when water is required, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your vehicle 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 have recommended in this guide 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.
