W205 battery

25 posts in this topic

OK my battery is at 75% after 2.5 years so I am thinking of changing it. I remember I once asked a petrol station guy and he told me stop start battery costs $400-600. I think that's quite expensive cos normal ones are only $150. I can switch off the stop start function. 

 

An thoughts?

If you replace your battery outside during the warranty period, will there be any issues with C&C? 

Thanks

Is yours w205? I thought 80ah Varta AGM battery size can't fit into the battery holder area. That's why I used back the exact spec as the original battery that came with the car. 70AH

Hello,

Can you tell me what is the brand of the battery that we get when the car is new ?

And is it better to buy the same brand ? Have you checked if it's cheaper to buy it somewhere else but Benz dealer ?

Thank you.

Hi,

the default battery is likely from Merc OEM from Varta. 

If you have cnc service credit can get from them for peace of mind or can get from any stockist or workshop that carries AGM type battery.

W205 should be 70Ah as mentioned by members in earlier post.

Just call this number 96589770. He will arrange the battery replacement at Sin Ming Mid View. Is your choice 70ah or 80ah AGM. I took the 80ah. Replacement is very straight forward.  15mins work.

Oh ! Very interesting to know, thank you ! So it could be a sign that the battery will need to be changed soon.

Do you know if I should change it as soon as start / stops fails ? Or can I wait longer without risk if I disable start/stop ? (but maybe if the battery is too weak, this function will automatically be disabled ?)

 

Thank you so much !

Guess it depends on ur mileage and if the car is driven daily.

Would suggest to change if sign shows to prevent can’t start engine at all.

I thk after stop start fails, the battery  can still last. Just that it cannot hold a charge. Might be risky if one day cannot start in the morning. Troublesome and costlyq by then.

Hello, do you know if it's more expensive when having it changed by the dealer ? Did you change it yourself without any problem ? Thanks.

Went for 60,000km service with cnc with eco start stop not working. Service advisor say main battery weak and quoted $500+. I ask them isn’t this due to auxiliary battery aka capacitor bank, they say w205 only has one battery which is the main. Eco strt stop use the converter. 

Anyway I learnt from Mb forums that auxiliary battery = converter which consist of some capacitor and an electronic board 

Cnc claim vehicle will not start if I don’t replaceand battery warantee is 2yr or 30,000km which ever early

Cut story: I bought a varta battery from Stockist and went workshop. Workshop did a battery check on existing battery and it has 42% left. So never change. Now I suspect is aux battery which is just some capacitor to hold charge is not working 

is cnc test different from workshop? 42% capacity left will fail their battery test?

Going back to ask them if can claim warrantee

Very likely is a converter fault. My friend had the same issue and got his converter replaced under warranty

Did some research. 

If the “auxiliary battery” aka converter is faulty: the eco logo likely will not appear.

if the eco logo appears but always Amber, then should be main battery weak. 

Went ahead to to replace the main battery and yeah the eco is working now. Not that I am using it though..

If you do a search on Varta battery finder, they will recommend both 70 and 80 Ah.

Was quoted $320 net with installation.
