Battery dead after working in the van

[Dellmassive]

Out of interest, where should you clamp the charger then? When I jump started yesterday, I did just that

a quick jump-start to get a van with a "flat battery" running is fine "direct across the battery" - and what i do. (as there is no quantifiable amount of energy transferred in respect of the battery's SOC - so the SOC will effectively remain the same) (SOC - State Of Charge)

but any other long term charge or discharge items should use a separate body - ground.

so EHU chargers, solar, etc etc - body - ground

and all fed power devices, DC-DC, Lights, Fridges, radios, GPS, Satnav, dashcam etc etc etc - body - ground

this is so the sensor on the battery NEG post can monitor all power in/out of the battery to determine its SOC


more on that here:

Battery Charging - Main Battery Chassis Point -

Battery Charging - Main Battery Earth Point - so weve all be told NOT to bridge out the battery monitor on the neg side of the battery when charging it. This is so the ECM can correctly gauge the SOC (state of charge) of the starter battery by monitoring the current flow in and out of the...

Which Jump Starter?

Advice required. Hi guys - I thought it would be prudent to carry one of those small JumpStarter powerpacks about with me as I have an electric lift seat installed for my better half and am a little concerned that with the extra demands on the van battery I might get caught out one wintery...

you should only have one cover . . . that's on the POS post to remind you not to clamp chargers to that post.

The cover is on the NEG post to remind you not to connect the charger there.

OOPs. . . . . Typo - Thanks @Grim Reaper

post error corrected.

Right..... I’ve replaced the battery and coded the change in serial number and the type to ‘AGM’ using OBDeleven. Can someone please tell me exactly how to change the voltahe capacity to the new battery? I have the newer type OBDeleven reader which has a different format and im using it via Apple iOS (not android).

Thanks again, hugely useful forum!

read through this thread, it may have pointers?:

@mmi - any input regards to OBD11?

Upgrading Starter Battery - how to guide

My van (April 2017 T28) is fitted with a Moll battery. I am experiencing some issues with it not starting after a few days sitting on the drive. Now this could be due to the tracker I have fitted draining it but I doubt it, I'll do some drain current tests before taking the plunge. If I were to...

Hi, thanks. I’ve read through all that already. I can’t find a way of changing the new battery voltage capacity using the iOS system.

I’ve done below successfully but as I say, cannot see how to adjust voltage. Is this necessary?

 

[Dellmassive]

voltage ? - no they are all 12v

just capacity 95Ah, and type - AGM

 

[WeaversT6]

Sorry, meant capacity! How do I change that?

 

[Dellmassive]

i havent got OBD11 . . . (I've got Carista and VCDS)

is this any help:

Battery Replacement | OBDeleven

Saw the following article here (thanks to EFF11 For the info) and below is the detail of how to code the change

[WeaversT6]

Sadly not, the newer OBDeleven iOS has a different format. All seems fine with the van after battery change other than start/ stop not functioning

 

[WeaversT6]

I need to know what channel to enter etc....

 

[WeaversT6]

I would need to know what channel gives access to the battery within ‘Gateway19’ and adaptation

 

[Dellmassive]

ch4 for battery ?

OBDeleven - IOS coding is shown as "In Development"

so not sure - have you got access to Android phone or tablet?

Android:

Somewhere I think, my daughter has a tablet, I’ll dig it out. Yeah, I can follow channel ‘4’ for battery but I can only change the serial number and type.

 

[Dellmassive]

I've just purchased OBDeleven so i can start testing it,

but im Android . . . . so not that much help re IOS.

 

[WeaversT6]

Ok, found the android tablet so I’ll get it plugged in

 

[WeaversT6]

Ok, plugged in. When I select Gateway (19) and then Adaptation I don’t get a full drop down list. It still asks me for a Channel. If I enter channel 4 it says not available

 

[WeaversT6]

Effectively I can work out how to access the battery in a similar way to how I did it using iOS, this will allow me to change battery type and serial number but not change capacity details

 

[WeaversT6]

this shows that the swrial number has been recorded as changed but no access to capacity
