- How to Change a Car Battery and not Lose the Radio Settings, Home DIY
First the health and safety bit.
This video is not for children.
Take care when handling a car battery as they do contain a corrosive, acidic solution which can cause a chemical burn. Take extra care if there are signs of corrosion to the battery or the battery terminals.
Where appropriate protective clothing.
If you are not confident in what to do then just take your car to a garage to get the battery swapped over.
Take care not to touch both battery terminals at the same time with a metal object.
Tools Required:
Spanner or socket set,
Possibly star key bits,
Screwdriver may be required,
Cleaning cloth,
Gloves,
Jump Leads
New battery that is as specified.
Basically my car battery died the other day and today represented the first opportunity to get a new one, and fit it.
I always find it a pain that after changing a car battery the car radio has lost all memory or other functions. Some vehicles can also lose other electronic functionality such as to electric windows and sensors.
To avoid this problem commercial solutions are available within a proper garage set up but all I had available was my other car and it’s car battery.
My stages.
Remove protective cover to the positive battery terminal.
Undo and remove any casing, bracket etc that is holding the battery into position.
Attach jump leads from alternate battery source to the terminals clamps that are on the battery to be removed. Place the negative (black) lead on first, with positive (red) lead on afterwards. By placing on one lead at a time you reduce the chance of both leads touching each other to create a short circuit and spark.
Loosen fixing clamps to the battery terminals and then remove.
I had to remove the air filter box in order to remove the old battery but I have never had to do that with any other vehicles before.
Remove old battery.
Fit new battery, making sure it goes in the same way as the old one previously sat.
Re connect the terminal connection leads, and tighten fully.
Remove the jump leads.
Refit any bracket or casing to hold the battery securely back into position.
Ideally re-grease the battery terminals to add additional protection from environmental moisture, dirt and contaminants.
Refit the protective cover to the positive terminal.
Secure the car bonnet back down.
Put car keys in the ignition and check the car starts okay and radio etc function as they should.

I was impressed how the clips stayed on. I can see them slipping off. Nice video!
Thanks for watching and your message.
Some cable clamps are definitely better than others. My old set would struggle to hold onto anything.
Good luck with your car 🚙
Great! I have a little 12v battery pack that I can hook up to my car. Thanks for the video...
Good luck with the swap over 🛠️🪴
@@diyhomeandgardening Just got done a little bit ago, and it worked like a charm. Radio settings, bluetooth connection for phone, clock etc.. Like I never touched it.. First thing I noticed was the alarm didn't go off when connecting the new battery, then I noticed the clock still had the correct time.. Thanks again...
@@Ottonic6 Dano, glad it all worked well for you.
Have a good day 👍
The plastic covers are primarily to protect against accidental short circuit, not water
Thanks for watching and messaging. Correct in they are to protect from short circuit and damage of all kind to the terminals
Hey great video :) Can you tell me if another car has to be turned on while swapping the batteries or is it enough to just connect the cars with the jumper cables?
Hi Stefan. Thanks for the question. You don’t need the other car to be on, just connect to the battery via cables for continuity of supply.
Hope that helps.
@@diyhomeandgardening Thank you very much sir!
@@stefanmanojlovic1582 no problem. Hope it helped. All the best
Not just radio station. But whole computer system including tyranny.
PS need to put steering wheel on the left side of cabin
Thanks for the message. So you drive on the wrong side of the road then😂😂
Hope it works for you.
Could same be done but using a battery booster?
Hi.
Thanks for watching and the message. I would think so but having not tried it I wouldn’t want to say for sure.
If you try and it works then please share.
All the best
@@diyhomeandgardening I did the above yesterday and worked as well as connecting another battery. Everything was saved with no issued (2008 1.8 Ford Focus Titanium)
@@aidyFF nice one with the experiment and thanks for sharing the success 👍👍
So you put 24v through a12v system?
You are not running the vehicle so the alternator isn’t kicking in to effect the loading. Also, you are disconnecting one battery that is not holding proper charge straight after connecting the second.
So long as you don’t connect to a battery being charged by an alternator you are fine, as is the car system which is load protected.
That's not how it works, the battery would need to be connected in series to be 24 volts
@@jonathankatz9471Also you would need 2 fully charged batteries in series to produce that voltage.
@@diyhomeandgardening spot on
He connected them in parallel (2nd batt neg to neg original batt, pos to pos on batteries), which keeps the 12v and increases Ah or cranking power. To increase to 24v you connect in series. Can be other way around, but for eg original battery neg leave in its current connection location, then its pos goes to the 2nd batteries NEG.. Then 2nd batt pos connects to vehicle power.
