Leisure battery flat after 2 weeks

[Chainline]

Anyone have their leisure battery go flat (new, fitted by dealer prior to delivery) after a couple of weeks.

I’ve been on holiday, come back, went to put some things in the grand and leisure batt is flat as a pancake.

I’ll isolate going forward but seems odd with a new battery as though some thing is draining it.

Nothing was ‘on’

There’s only 2 things it could be,
Something draining it
Or defective battery, To be fair batteries are pretty good nowadays but on saying that I do come across defective ones on brand new vehicles at the PDI stage but certainly not common,
The best thing to do is fully charge the leisure battery and put a amp meter in series to check for parastatic drain, This maybe something for the supplying dealer to sort out for you.

That’s normal for a GC with no solar, only way to stop it is use the big red isolator switch, it’s what it’s there for.

I’ve got a battery monitor on the leisure battery & it shows a steady discharge - about a week from full to flat unless isolated.

Totally - flat in 1-2 weeks without isolator (even with switching off everything including trauma unit).

However, 1 hour-ish to charge fully while driving.

Set off yesterday - was fully flat (3.5amp wouldn’t get the water pump going even), used it at the Big Feastival 3 weeks ago, but given the 10k worth of trips over the last year, have come to accept it… by the time we reached the Cotswolds (around 2 hour drive), I was spilling over with power.

So either isolate or recharge
