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 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 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 get started! …

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 1 day.

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

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

Instead, they die early because of poor maintenance and maintenance…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 has to be used gently.

  • Peak is the perfect performance phase, which we attempt to maintain 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 nevertheless be used for quite some time, but must be watched.

Around this time, you can 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 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 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 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 paste (one part water to three parts baking soda) within the corroded areas. 

The acid in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the rust away.   After the rust is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture.  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 (lights, radio, or electronics) before turning on 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 are 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 sort of use.

Rather, car batteries are meant to provide a sudden burst of power for ignition.  They’re 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 for a battery that powers electronics, instead of a battery that just provides you a burst of electricity for ignition, will damage the battery and significantly shorten it’s lifespan if it’s repeatedly used in this fashion.   So avoid operating any automobile accessories or electronics while the vehicle is off.

Tip 3: Make sure the car battery is safe and has good battery wires.   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 cause damage to your car whilst creating a security risk.   The same could happen when you have awful battery cables (or they are not connected properly).  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 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’ll tell you if your battery will match their kit — such as here (top of page).   These protective battery sleeves are typically made of 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 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 (radio, lights, etc.) or the car computers.   This is the reason why folks come home from long vacations and locate their car battery dead.   But to prevent 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 that they don’t always draw current from the vehicle battery when the car is off.   They’re also useful if you go on plenty 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 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’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 whether there’s 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 significant, ONLY use distilled water to refill your car battery).

Never overcharge your car battery. Lead-acid batteries release hydrogen and oxygen gases when they’re overcharged.  

  1. It can be volatile.

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