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

But lots of people find that they need to change their car battery every 1 to 2 years.

Why is this?

And what can you do to prolong your vehicle’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 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 anybody will be able 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 (but most people kill their battery well before it’s time)

Even if you care for 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 was charged or discharged.

But 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 dependable, and most widely used form of rechargeable battery in the world.

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

  • Peak is the perfect performance stage, which we attempt to keep for as long as you can.

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

Batteries in decline can still be used for quite a while, 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 not able to begin your car for work).

Tip 1: Do a monthly inspection of the battery terminals to make sure they are 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 car and many batteries are replaced because of a lot of corrosive build up.   But often times, this is readily treated simply by pouring a small amount 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 consume the corrosion away.   After the corrosion is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture.  Be sure to allow it to dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Do not run any car accessories (radio, lights, or electronics) before turning to the vehicle ignition and driving the car.   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 are just relying on the car battery to power those electronics. 

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

Instead, car batteries are supposed to provide 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 provides 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 car accessories or electronics while the car is off.

Tip 3: Make sure the car battery is secure and has good battery cables.   The battery has to be secured at all times.  If a battery is jostling around it will be impaired and might short circuit.   This may ruin the battery and even damage your car whilst creating a security risk.   The same could happen when 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.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your vehicle battery from big changes in temperature will help maximize 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 site where you can place in your car model and year, and it will 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 protect it while still allowing proper ventilation.

Tip 5: Fully charge 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 car is off.  This happens because current is drawn from the battery by car accessories (lights, radio, etc.) or the car computers.   This is the reason why people come home from long vacations and locate 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 electricity for the car accessories and car computer, so they do not continuously draw current from the car battery when the car is off.   They’re also useful if you go on a lot of short car trips (like to work and back daily ) and never give your battery a opportunity to fully recharge.  Repeatedly doing this will 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…be sure you fully charge your car battery at least once a week since it’ll greatly increase the life 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’s a demand for water.   So check the vehicle battery water level indicator regularly and if water is needed, refill the battery with distilled water (and that’s significant, 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 are overcharged.  

  1. It can be explosive.

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

Tip 8: Assess your vehicle’s alternator.   If you’re doing everything we have recommended in this guide but your car batteries are dying early, you’ll want to check 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.
