8 Simple Tips & Tricks To Double The Life Of Your RV & Car Battery

All You Ever Needed To Know About Getting The Most Out of Your RV Battery!

The battery in your RV and car should last at least 3 to 5 years… But many are finding that they need to replace theirs as often as every 1 to 2 years.

Why is this?

And what can you do to prolong your RV’s battery life?

We’ll be covering all that below…

  • We’ll explain why car and RV batteries die early… and how you can prevent this from happening.
  • 8 simple tips and tricks to maximize the lifespan of your RV’s 12 volt battery.

The tips you’ll learn below are simple to do… and anybody can do it (even if you know nothing about cars, RVs or batteries!).

So let’s get started!…

First, You Should Know That Every Vehicle Battery’s Lifespan Has A Limit (but most people kill their battery well before it’s time)

You should be aware that every battery has a limit to its lifespan. Even if you take care of your car battery perfectly… it will still die one day.

This is known as the battery’s “Calendar Life” and it’s entirely independent of how many times the battery has been 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 conk out early because of poor care and maintenance… which is easily avoidable if you know how.

A Little Background About Lead Acid Batteries…

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

They have three life phases – formatting, peak, and decline.

  • Formatting: when the battery is new and needs to be used gently.
  • Peak: the ideal performance phase, which we want to maintain for as long as possible.
  • Decline: a slow process, but one that eventually ends in the termination of the battery.

Batteries in the decline phase can still be used for quite a while, but must be monitored…

Around this time, you can either learn how to recondition the battery or keep a close eye on it and try to replace it before a problem arises (like being unable to start your car for work).

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

*Safety FirstPlease see the safety guidelines near the bottom of this page*

Tip 1: Do a monthly inspection of the battery terminals to make sure they are clean and corrosion free

One of the first problems that arises with vehicle batteries is the build-up of corrosion around the terminals.

This corrosion destroys the connection between the battery and the vehicle; many batteries need to be replaced due to too much of this corrosive build up.

However, this can easily be resolved by simply pouring a small amount of Cola or a DIY anti-corrosion paste (one-part water to three-parts baking soda) over the corroded areas.

The acid in the Cola or the alkalinity of the DIY anti-corrosion paste just eats the corrosion away.

Once done, use a clean damp rag or sponge to clean up the remaining residue and moisture. Let it dry, then rub some petroleum jelly on the terminals to prevent future corrosion.

*note: see our safety tips later in this article before disconnecting/re-connecting your battery.

Tip 2: Do not operate any car accessories (radio, lights, or electronics) before turning on the car ignition and driving the car

When the vehicle is running, the alternator generates electricity and charges the battery.

But if you use the radio / lights etc, without the vehicle on you’re just relying on the battery to power those electronics.

RV & car batteries are designed to provide a sudden burst of power for ignition; they’re just not made to give prolonged power for electronics and other devices. Used in this way, you’ll greatly shorten the lifespan of the battery. So avoid operating any car accessories or electronics while the car is off!

Tip 3: Make sure the car battery is secure and has good battery cables

The battery has to be secured at all times. If it’s jostling around it will be impaired and could short circuit. This will ruin the battery – and may even cause damage to 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 make sure they have a secure connection as well.


Tip 4: Insulate your car battery from extreme changes in temperature

Protecting your battery from large variations in temperature will help maximize the battery’s lifespan.

To do this you can use a car battery insulation kit. Newer model cars should already have these kits installed, 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 companies selling these insulation kits will have a form on their website where you can put in your vehicle model and year, and it will tell you which kit is required for your battery.

These protective sleeves are usually made of plastic or an acid resistant, thermal resistant material, and 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 RV or car battery drains even when the vehicle is off, due to current being drawn from the battery by car accessories (radio, lights, etc.) or in-car computers. This is why people come home from long vacations and find their car battery dead.

To prevent this, you can use either a car battery charger or a solar battery charger. These maintain the optimum charge level of your battery when the vehicle is not in use; they provide enough power for the the on-board accessories and computer, so they don’t continuously draw current from the car battery when the car is off.

These chargers are extremely useful for those who go on a trip or leave their car unused for a while… and especially for RV owners who go long periods between trips.

They’re also handy if you go on a lot 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 charger or are happy to interchange batteries (leaving one at home to fully charge).

The most important thing to remember is to make sure you fully charge your vehicle battery at least once a week because it will 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: Check your car battery’s water level 

Most car batteries indicate if there is a need for water, so check the car battery water level indicator regularly and if water is needed, 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 oxygen and hydrogen gases when they’re overcharged.

This causes two problems:

  • It can be explosive.
  • It breaks down the composition of the water in the battery – which shortens its lifespan.

Tip 8: Check your car’s alternator

If you’re doing everything we’ve recommended in this article but your car batteries are still dying early, you’ll want to check your car’s alternator (or get a mechanic to check it).

If your alternator is faulty it will result in ineffective recharging of your battery and dramatically shorten your battery’s lifespan.

What Can You Do if Your Battery Dies?…

If your vehicle battery dies or is in the decline phase all hope is not lost!

In fact it’s not vehicle batteries…. Our dependence on batteries has sky-rocketed over recent years with the exponential growth of electronics, so it’s no surprise that in the background people are working on methods to both cut the costs and the environmental impact of battery use.

Whether it’s the battery that needs replacing in your vehicle, your laptop, cell phone or the AA’s that power nearly every torch, remote and gadget it’s now estimated that the average person will spend $15,000 in a lifetime on batteries alone!

But – now there’s another way! American Tom Ericson recently released a revolutionary Battery Reconditioning program which teaches people how to recondition all types of old batteries and bring them back to 100% of their original working condition. And you can learn to do it RIGHT NOW!

It’s simple and quick… and he has methods for virtually any type of battery.



It’s recently featured on CNN and Fox News, and around 20,000 people are already reaping the benefits.

With all the buzz surrounding this system, last year we got a copy for ourselves to check it out… And it’s nothing short of BRILLIANT…

The course is made up of step-by-step guides that show you how to recondition each type of battery. And each guide is full of pictures and diagrams so you not only read exactly what to do… you see exactly what to do as well!

Different methods cover different battery types, but we’ve yet to find a battery that this doesn’t work on and quite frankly astonished that this information still isn’t more mainstream.

Must be a case of ‘only for those in the know’!


It’s still available today – but with so many people snapping up the course early on, Tom’s rumoured to be taking it off the market soon; he prides himself on providing excellent customer support which would be difficult to maintain for many more new members…

Curious?? Don’t miss out on this before it’s gone….It’s time to act quickly and join the battery revolution!





Important Safety Precautions:

Safety Precaution #1) Before disconnecting your car battery read the car owner’s manual first. Most commonly (if not stated otherwise in the owner’s manual) the negative cable is to be disconnected first and then the positive cable. When you re-connect the battery, connect the positive cable first and then the negative cable.

If done in the wrong order it may affect your car’s fuses and other electronics. Also, remove your car keys from the ignition before working on the battery. Some cars are more sensitive to this procedure than others – for example German marques (Mercedes Benz and BMW type cars) – so use extra caution.

Safety Precaution #2) If you are charging a battery do it in a well ventilated area. If you are handling a car battery that is installed you should open the hood of the car for a few minutes to allow for ventilation first.
