    Or, as in my case, the battery will be perfectly fine the day before and next morning, dead... :rolleyes:

    Mobilo tech said very common, modern batteries go on and on and then suddenly, dead. :shock:

    You dodged a bullet!
    My halfords battery failed after two years and they offered to replace it and fit it for me for the extra £6 (I should have known this would end bad)
    This guy did not have the right tools, left the terminals loose... I had to ask him to stop, got the idiot to call the manager and finished the job my self. Manager didn’t seem to care that he had left the terminals loose.

    You were lucky, they usually say it is the car and that their battery is perfect, not nice people to do business with

    Sorry to state the obvious, but you only get what you pay for. An unqualified counter staff in Halfords should not be let loose with a car, what worries me more is that the manager also knew or cared no more than his staff.

    I wouldn't let Halfords change my car battery. I was just asking because I'd seen something in the paper with their fitting prices & nothing seemed to 'from £??' So, knowing that my battery could potentially be a PITA to fit, I asked & they said they'd not touch a car like mine. ;)

    Surely a back up power source is only to retain memories etc ...... there has to be a time when you might need to disconnect a car's battery to work on it. eg alternator :confused::confused:

    Colin has done a very good DIY for the 203, the 203 is the only one where things can go wrong.

    One should always take care, if a battery has just been on charge disconnected, as the voltage could be too high, and best to cream a little off the top before connecting to cars with wake up systems, in these cases it best to have the doors closed but no possible when the battery is under the rear seat.

    I was in a local retail park one day parked just outside halfords . it was ****in down.. and a halfords employee was trying to close a door on a car. he opened it,banged it, opened it slammed it then went inside for a spanner to adjust the hinges ..
    I watched with some interest and then saw that the owner was disabled.. ..so got out had a look and asked why the hinges would need adjusting.. thinking he my have reversed with the door partly open and caught on a bollard or something
    The halfdords guy pushed the door closed and said look it wont close it is too far out of line.. I lifted the door handle and had a look .. the lock had been closed on the door.. and each time the guy banged it, the lock became lodged and wouldnt release with the handle... so a scewdriver and I opened the catch and then gently closed the door.....

    Talking of halfords charging to fit various parts, (and appologies for going off topic), I bought a set of Bosch wiper blades and was asked if I wanted them fitted at an extra cost of £3? WTF??

    The wipers took seconds to fit! Who pays to have wiper blades fitted?? :shock:

    People must do, otherwise Halfords wouldn't offer the service ....... I've come across loads of people that don't have a clue how they clip on

    Me too and can't change wheels,bulbs,check levels in fact check anything.
    The best would be a person who had no idea their car had five gears after two years of ownership.

    I changed the battery on my S203 this week. I browsed through the forum looking for warnings on my model and it seemed the only issue was to remove negative first... which is logical any way, I think. Once I had removed the positive I put the terminal inside a rubber glove just so that it would only go "live" when I was ready.

    I decided to go for a quality item - the one I was removing had lasted the life of the car (2007) and only let me down once, a couple of weeks ago and I was twitchy whether I really needed to replace it because after the car was restarted, I drove about 15 miles and it was back the way it's always been - turn the key and it starts - first time, every time! I ordered a unit from MB Avonmouth... it arrived incredibly quickly - no complaints at at all.

    Changeover was easy except for two things: 1) there's a breather/overflow pipe on the battery and I though I was being clever putting the "L" shaped connector in first - and in the process of installing it I sheared the expletive thing off! Waiting for a replacement... I do think you need muscles on your muscles and hands like shovels to do the battery fitting - it weighs a ton and of course it has to be fitted right at the back in front of the bulkhead.

    As I said, I checked all the postings on the forum and there was nothing for my C220 to really worry about so I went for it! I checked and initialised the windows - no problem and turned the power steering to both locks - again no problem, so I sat there feeling smug until I realised the indicators/main beam switch was inoperative. I had just got my long nose pliers ready to check the fuses when I had a thought... with a computer, you switch everything off, reboot and off you go. So I did just that: I truned everything off, removed the key, took a deep breath and put the key back in again. No problem! Not only is it back to working as I would expect but it retained all the OBD settings such as auto-locking and mirror folding.

    So now I'm really smug! Unless of course tomorrow....

    Not so much with MB but some manufacturers have a battery replacement re-initialization.

    This includes such routines as

    1. Turn ignition on leave for 1 minute with lights on dipped beam. (throttle body relearn)
    2. Start engine and leave at idle for 15 minutes do not touch throttle. (voltage stabilization relearn)
    3. Stop engine remove key restart immediately,
    observe idle rpm @1100 lowering to 800rpm after cold start process. (Idle charge state relearn cold starting auto box)

    That's just a basic little Suzuki with autobox that can have cutting out at cold idle problems.

    So changing batteries isn't as simple as it used to be with the electronics on board vehicles these days.

    I suppose this thread would get some more interesting replies on a Tesla forum.

    It looks like the manufacturers/dealers/schools/society/whatever has finally frightened the great British public into "leaving it to the Professional". I guess it had to happen sooner or later.

    It started with "sealed for life" components in the 70's, and carried on from there, but don't get me started on Quinton Hazel...

    The real problem comes when you see the "professional" doing the job and don't realise what a Muppet he has revealed himself to be...

    Then we really ARE screwed.
