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?

Well… That’s what we’ll discuss in this article.



The tips we’ll teach you in this guide will be easy to do…and anyone will have the ability to do these (even if you know nothing about cars or car batteries).

So let’s begin! …



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.


Instead, they die early because of poor maintenance and maintenance…which you can do something about.

Lead acid batteries are the earliest, most dependable, and most widely used type of rechargeable battery in the world.



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

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


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 not able to begin your vehicle for work).



The acid in the Cola or the alkaline properties in the DIY anti-corrosion paste will eat the rust away.   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 (radio, lights, or electronics) before turning to the car 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 is not on, and you’re using the car’s electronics, you are just relying on the car battery to power those electronics. 

This is detrimental to the car battery because car batteries aren’t meant for this type of use.


Tip 3: Make sure the car battery is secure and has good battery cables.   The battery needs to be secured at all times.  If a battery is jostling around it’ll be impaired and might short circuit.   This may ruin the battery and even cause damage to your car whilst creating a security risk.   The same could happen if you have bad battery cables (or they’re not connected properly).  So check your cables and make sure they have a secure connection also.


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 vehicle is off.  That happens because current is drawn from the battery by car accessories (lights, radio, etc.) or even the automobile computers.   This is why people come home from long vacations and find their car battery dead.  

Car battery chargers (regular or solar) will maintain the optimum charge level of your car battery when the car is not being used.   They do it by providing enough power for the car accessories and car computer, so that they don’t always draw current from the vehicle battery when the car is off.   As you can imagine, these chargers are extremely useful…especially if you go on a trip or leave your car unused for a while.  They’re also useful if you go on a lot of short car trips (like to work and back each day) and never give your battery a opportunity 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 charge.   The most important thing to remember with this tip is…be sure you fully charge your car battery at least once a week since it will greatly increase the life of your battery.  Do this using a charger, interchanging batteries…or simply going on a car ride long enough to recharge the battery.

Tip 6: Assess your car battery’s water level.   Most car batteries indicate if there’s a demand for water.   So check the vehicle battery water level indicator frequently and if water is required, refill the battery with distilled water (and that is important, ONLY use distilled water to refill your car battery).

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