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.

Why is this?

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 keep this from happening.

We’ll also give you 8 easy tips and tricks to maximize the lifespan of your car’s 12 volt battery.

The tips we will teach you in this guide will be easy to do…and anyone 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’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 known as the battery’s”Calendar Life” and it’s completely independent of how often the battery was charged or discharged.

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

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

Rather, they die early due to poor maintenance and maintenance…which you can do something about.

Lead acid batteries are the oldest, most reliable, and most widely used form of rechargeable battery in the world.

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

  • Peak is the ideal performance stage, which we attempt 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 must 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 unable to begin your vehicle 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 make sure they’re clean and rust 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 due to a lot of corrosive build up.   But often times, this is readily 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 acidity in the Cola or the alkaline properties at the DIY anti-corrosion paste will eat the corrosion away.   After the rust is eliminated, use a clean damp rag or sponge to clean up the remaining residue and moisture. 

Tip 2: Don’t run any car accessories (radio, lights, or electronics) before turning on the vehicle ignition and driving the vehicle.   When the car 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 are using the car’s electronics, you’re simply relying on the car battery to power those electronic equipment. 

This is damaging to the car battery because automobile batteries aren’t meant for this sort of use.

Rather, car batteries are supposed to offer a sudden burst of electricity for ignition.  They’re not made to offer prolonged power for electronics and other devices (that’s 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 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 vehicle is off.

Tip 3: Make sure the car battery is safe and has good battery cables.   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 bad battery cables (or they’re not connected properly).  So check your cables and be sure they have a secure connection as well.

Protecting your vehicle battery from large changes in temperature will help maximize the battery’s lifespan.   To do this you can use a car battery insulating material.   Newer model cars already 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 put 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 car 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.  This happens because current is drawn from the battery by car accessories (radio, lights, etc.) or the car computers.   This is why folks 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 vehicle is not in use.   They do this by providing enough electricity for the car accessories and car computer, so that they don’t continuously 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 this will dramatically enhance your battery’s life — unless you use a car battery charger or interchange batteries, leaving you at home to fully charge.   The main 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 simply 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 is a demand for water.   So check the car battery water level indicator frequently and if water is needed, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your vehicle battery).

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

  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’ve recommended in this guide but your automobile batteries are still dying early, you’ll want to check your car’s alternator (or find a mechanic to check it).
