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

But many people find that they need 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 offer you 8 easy tips and tricks 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 be able to perform these (even if you know nothing about cars or car batteries).

So let’s begin! …

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 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 many times the battery was charged or discharged.

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

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

Instead, 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.

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 perfect performance phase, 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 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 before a problem arises (like being unable to begin your car for work).

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

Tip 1: Do a monthly inspection of the battery terminals to make sure they are clean and corrosion free.   One of the first 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 several batteries are replaced because of a lot of corrosive build up.   But often times, this is easily treated simply by 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 at the DIY anti-corrosion paste will eat the rust away.  

Tip 2: Don’t run any car accessories (lights, radio, 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’re using the car’s electronics, you’re simply relying on the car battery to power those electronics. 

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

Rather, car batteries are meant to offer a sudden burst of electricity 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 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 is 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 good battery wires.   The battery needs to be secured at all times.  If a battery is jostling around it will 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 if you have awful battery cables (or they are not connected correctly ).  So check your cables and be sure they have a secure connection also.

Tip 4: Insulate your car battery from extreme changes in temperature.  Protecting your car 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 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 proper ventilation.

Tip 5: Fully charge your car battery at least once a week (use a car battery charger or interchange batteries 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 (radio, lights, etc.) or the automobile computers.   This is the reason why people come home from long vacations and find their car battery dead.   But to avoid this, you can use either a car battery charger or a solar battery charger. 

Car battery chargers (regular or solar) 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 that they don’t always draw current from the car battery when the car is off.   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 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 main thing to remember with this suggestion is…be sure you fully charge your car battery at least once a week because it’ll greatly increase the life 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 vehicle battery’s water level.   Most car batteries indicate if there’s a need for water.   So check the car battery water level indicator frequently and when water is required, refill the battery with distilled water (and that’s important, ONLY use distilled water to refill your car battery).

Tip 7: Do NOT overcharge your car battery.   Never overcharge your car battery. Lead-acid batteries release hydrogen and oxygen gases when they are overcharged.   This causes two problems:

  1. It can be explosive.

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