Vw t6 - T6 starts yet sounds like the battery is almost flat

[Medsi]

Hi Does anyone have the same issue as me on my van, T6 starts yet sounds like the battery is almost flat, but it’s a new battery

Are you confident that the battery is fully charged i.e. been on a decent drive very recently, or has been charged for a decent period with a smart charger ?
Even new batteries will drop their voltage if they aren't charged.

As above, also.

Possible issue with startermotor or link cable from starter to battery.

Got a few pics of the battery and terminals?

What battery did you have before? . . . Did a shop change it for you?

Hi and thanks for the replies, the battery terminals are very clean and tight I’m getting 13v dc from the battery and I use the van all day every day going from job to job. I hope this helps

Roughly how many miles do you do in a day ?

As Dell suggests, it’s worth checking the cables and connections before you start to investigate if the starter motor is at fault.

Pete
Probably about 10 miles a day on average, I’ve just finished checking the connections and I’m mow going to charge the battery and I’ll see what happens.
Thanks

Yes, 10 miles a day is not a lot - could well be a depleted battery.

Thanks Pete I’ll do a bit more digging and come back then

there was a recent post on T6F with similar issue - - - they had water ingress in the starter + needed new main starter cable. (after having new battery fitted and tested etc)

for now:

follow @Pete C advice and fully charge the battery for 24hrs on a smart charger . . . then retest.

when charging the T6 battery (in vehicle) , don't use the battery NEG post - use another ground point !! (dont bridge out the NEG post battery sensor)

Check the earth strap between the chassis and engine (at the Cambelt end) I have just helped a member with a similar non-starter and the terminal had corroded.
