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

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

Why is this?

And what can you do to prolong your vehicle’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 simple tips and techniques to maximize the life span of your car’s 12 volt battery.

The tips we’ll teach you in this guide will be simple 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 (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 one day.

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

However, most car batteries never make it their complete”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 type of rechargeable battery in the world.

Lead Acid Batteries have three life phases — formatting, peak, and decline.

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

  • Peak is the ideal performance stage, which we seek to maintain for as long as you can.

  • Decline is a slow process, but one that 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 until 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 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 vehicle and many batteries are replaced because of a lot of corrosive build up.   But often times, this can be easily 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 rust is gone, use a clean damp rag or sponge to clean up the remaining residue and moisture.  Make certain to let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

Tip 2: Don’t operate any car accessories (radio, lights, or electronics) before turning on the vehicle ignition and driving the car.   When the vehicle is on, the car 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’re just relying on the car battery to power those electronics. 

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

Rather, car batteries are supposed to provide a sudden burst of electricity for ignition.  They are 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 power 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 vehicle is off.

Tip 3: Make sure the car battery is safe and has great 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 damage your car while creating a safety risk.   The same could happen if you have bad battery cables (or they’re not connected properly).  So check your cables and be sure they have a secure connection also.

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 insulation kit.   Newer model cars currently have these kits installed typically.  But if your car doesn’t have one, you can easily install 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 site where you can place in your car model and year, and it will 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 guard it while still allowing appropriate 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 even the automobile computers.   This is why folks 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 vehicle is not being used.   They do this by providing enough electricity for the car accessories and car computer, so they do not continuously draw current from the vehicle 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 plenty of short car trips (like to work and back each day) and never give your battery a chance to fully recharge.  Repeatedly doing this will dramatically shorten 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 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 need for water.   So check the vehicle battery water level indicator regularly and if water is needed, 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 oxygen and hydrogen gases when they’re overcharged.  

  1. It can be volatile.

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

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