Read Our Guide, “Is It Safe To Change Your Own Car Battery?”, To Help You Make The Right Decision

Change Your Own Car BatteryIt astounds us, without sounding biased, how many do-it-yourself vehicle battery installations are performed without knowing the real dangers to both the person involved and the vehicle’s electrical system. Take into account also; they are items filled with “Highly Corrosive” sulfuric acid, which produces hydrogen and oxygen while being charged, making them “Highly Flammable”. There are specific safety procedures, equipment and installation know-how to ensure a safe environment when fitting batteries.

So, Should You Change The Car Battery Yourself For The Sake Of Saving A Few Dollars?

Firstly and foremost, only qualified personnel should undertake the replacement of automotive batteries to avoid costly repairs to both your vehicle and possible injury to oneself. It is especially true since they are classified as “Dangerous Goods” and “Hazardous Waste”.

For example, if you remove the battery cables in the wrong sequence, you will most certainly create a “Spark” or “Short Circuit”. It will either weld the ratchet being used to remove the battery to the vehicle’s chassis, leaving the battery in a volatile state for exploding and causing a fire. As you can see, the danger is real and the very reason why you should avoid doing it yourself.

Secondary factors, after your safety, is the damage your vehicle’s electrical system is prone to if a “Short Circuit” is produced. The cars electronic circuit boards and onboard computers are susceptible to “Shorts” and may experience permanent damage. It is especially true in modern cars, and the replacement of these components can be a very costly exercise. When disconnecting a battery from a vehicle, a “Power Source” must be still available to avoid losing your driveability computer settings and radio’s security code.

Once again, this can be a costly inconvenience looking at it from a perspective of the time required to acquire the radio’s security codes if you have no record of them or worst scenario; the vehicle needs re-programming of onboard computers at the dealership’s workshop due to complete loss of power.

In some cases, it’s not the battery that’s at fault!

Before you change the car battery yourself, the first step is to diagnose if it’s faulty by performing a “Digital Test”. Once again, this is where experience and the correct diagnostic equipment is required to determine if the battery is defective or another major auto electrical problem is present. In some instances, we see them unnecessarily replaced when the main underlying problem was either a faulty alternator, starter motor or parasitic drain.

It’s essential you dispose of your old battery responsibly

Once the old battery is removed, it must be discarded responsibly and legally. The fact is, too many do-it-yourselves illegally discard old auto batteries, i.e., in household rubbish bins which end up in landfills, and in some cases we see them thrown onto the roadside and bush-lands.

By hiring a professional car battery replacement service, you can rest assured that they will properly recycle the old battery to manufacture new products and protect our environment.


Truthfully, from a safety perspective, we advise you not to change your car battery yourself. Book the professionals, “It’s better to be safe than sorry.”
