Upgrading Starter Battery - how to guide

[LambethBoy]

Ok need to get this done now as startup/turnover is getting strained/struggling.
I don't think i really need any extra Amps?, van is run as standard with some extra usb charging points in the back for the kids but the are only used while driving.
So recommendations on batteries please, Euro 6 with stop/start

You need to at least match the capacity and cranking amps of your existing battery.
These should be on a label on the battery - can you post a photo of it ?

I fitted this one. Bought via eBay with free delivery and 5% discount. It was a straight replacement for the OEM and easily coded with Carista. It also has a 5 year warranty like the Bosch equivalent which I think are made in the same factory.

Suppose I could go up some amps

Just had mine checked out after 6 years since new. It’s good. Mine is 105ah and came with the van. T32 DSG Highline.

Have you got a picture of your battery please?

Oops I have. It is a 75ah the 105A on the label confused me

See the post above by @Higgidav (Upgrading Starter Battery - how to guide) and the numerous other recommendations through this thread.

Thank you everyone, bought a Bosch battery, slightly larger (80ah vs 68ah), swapped it in, changed the details in Carista, done. Could not have been easier and I’m sure being well prepared and advised helped!
Cheers

The battery can be replaced with a new one with different capacity and even different type. Just let the van know by using the VCDS.

VCDS - Module 61 - (Long) Adaptations - Channel 04. Hover the mouse over data fields to get the instructions what to type in (screenshot below).

Battery Type is defined in the Codings - Byte 02:

Just checked the stored value for mine and it is 150 VA0 191211B2DK but I think it was just a 65AH or 70AH not 150AH, I have just put a replacement battery in of 80AH so changed the first 3 digits to 080, I wasn't sure on the manufacturer (Mercedes branded) so I left it as Varta.

Hi all

Need some help, I got a new upgraded Bosch battery to install but my vcds isn't working. What are my options? Can i install to get me going and code later? Or is this not a good idea.?

 

[Pete C]

Yes, you can just install it and go. Coding it in just optimises the charging from the point of installation.

So can I change from 70ah EFB to a 95ah Agm? Won't that damage the new battery?

 

[Grim Reaper]

No, they are similar characteristics, and the new battery being larger than the old just means it won't get charged up as much. the only thing I wouldn't do is go from EFB/AGM to regular lead acid.
Just get the coding done asap

Hello. So just swapped my OEM starter battery for a new Bosch AGM battery as battery tests show it was pretty much dead.
Anyway, fitted ok. How do I code it in using OBDeleven? I would have thought there would be a nice barcode I could scan on the Bosch like there is on the Varta, but there isnt.

How do I find the module on OBDeleven where i enter that it is AGM (or fleece as it seems needs to be entered).

What code would I enter tfor the new Bosch battery? What is the vendor code for Bosch.

Any help would be much appreciated

All the info is in this thread, read carefully from the beginning.

Did you have any vent plugs to remove? Got mine yesterday and they both seemed to be sealed

 

[doningtonphil]

I hadn't seen any mention of vent plugs. Do AGM batteries need venting?
