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

But lots of 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 vehicle’s battery life?

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

We’ll also give you 8 simple tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this article will be easy to do…and anybody will have the ability 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 is completely independent of how often 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.

Lead acid batteries are the earliest, 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 phase, which we seek to maintain 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 a while, 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 not able to start your car for work).

8 Simple Tips To Prolong The Life Of Your Car’s Lead Acid Battery

Tip 1: Do a monthly review 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 a lot of corrosive build up.   But often times, this is readily 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 acidity in the Cola or the alkaline properties in the DIY anti-corrosion paste will eat the corrosion away.   After the rust is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

Tip 2: Don’t operate any car accessories (lights, radio, or electronics) before turning to the car ignition and driving the car.   When the car is on, the auto alternator generates electricity and charges the vehicle battery after the battery has a voltage drop.   But if the car is not on, and you’re using the car’s electronics, you are simply relying on the car battery to power those electronics. 

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

Instead, car batteries are meant to provide a sudden burst of power for ignition.  They are not made to offer 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 that powers electronics, rather than 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 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 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 cause damage to your car whilst creating a safety risk.   The same could happen if you have bad battery cables (or they are not connected correctly ).  So check your cables and be sure they have a secure connection as well.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car battery from big changes in temperature will help maximize 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 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 fit their kit — such as here (top of page).   These protective battery sleeves are usually made from plastic or an acid resistant, thermal resistant material.   These automobile battery insulation kits will insulate your battery and guard 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.  That happens because current is drawn from the battery by car accessories (radio, lights, 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 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 they do not always 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 helpful if you go on a lot of short car trips (like to work and back each day) and never give your battery a opportunity to fully recharge.  Repeatedly doing so will dramatically shorten your battery’s life — unless you use a car battery charger or interchange batteries, leaving you 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’ll 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: Assess your vehicle battery’s water level.   Most car batteries indicate if there is a demand for water.   So check the car battery water level indicator frequently and when water is needed, 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’re overcharged.

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