Replacing Battry on 53 (W203) C270 CDI

[Goldreef]

Hello,

I have been experiencing problems with a drained battery and had to jump start my car today using the procedure recommended in the manual. This is my own fault as I only use the car at the weekends and use the train for commuting.

However I noticed that my current battery (which is 5 years old) is a Bosch S5 (which provides 510 starting amps and 65 Amp/hours). I have enquired with my local Cost Co about a new Bosch battery and can provide me with the recommended Bosch S6 002 (which provides 850 starting amps and 95 Amp/hours) for £81, however before changing battery, I was wondering if anyone may confirm the following:

The car is fitted with an Audio10 CD/Radio made by Becker. The car manual nor Audio10 manual mentions a radio code being required upon changing the battery, only reseting the ESP and Side Windows. Would I require a radio code (I was not provided with this when I purchased the car)?

If I connect my car up using the jump start connecter under the bonnet to another car whilst carefully changing the battery in my car, would this keep the circuits in the car live and circumvent the need for a radio code and reseting the ESP and Side Windows?

I realise that I may have to begin using the car at least 2 days a week to commute aswell as at the weekend in order to keep the battery in good condition, however thought a new battery would not hurt either

Many Thanks in Advance,

John

Cole,

Thank you for your reply, this was exactly what I was looking for. To be honest I had ran a search on the forum, however forgot to read through the DIY section first.

Unfortunately I had to jump start from another car, however as my battery was just shy of the required output to start the engine, I didn't start the 'donor' car and did not leave the jump leads connected for longer than it took to start my car sucessfully. Thankfully no errors have been reported by the car following the jump start.

Many Thanks,

John

I too have been having issues with my battery and am considering replacing it - however, I know read there are several different types - namely Bosch (my preferred option) S3 096 - S5 019 and a S4 096 and a S5 096 - now I'm really confused! I also read somewhere that the bigger battery helps deal with all the load forced upon it - i.e. seat heaters / climate control / windscreen wipers etc etc I don't mind paying for the S5 - which is on offer at the moment for £112 inc vat. Obviously I would need to fit it myself. Answers / advice muchly appreciated.
Incidentally, I'm a newbie to the forum and to MB in general! Already thinking about an E class E320 ;-)

Very easy to fit yourself..
I removed and replaced mine once when looking for my siren (I didn't know its location at the time)..
No issues for me..
Its located beneath the pollen filter (See photo)..
It is very heavy so have your porridge first !!
