Battery drain?

[Cornershop]

Thanks both for your assistance.

I have the 5A Ctek and charged it to 80% as I had to drive the car the next day. I'll remove it tonight to give it a full recondition charge.

I've not checked the plenum drains since ive bought it but did clear the 2 wheel arch drain just after xmas. You could be onto something there as if there was any water in that area, it would drain towards the ECU etc the way i parked it.

I may call the RAC out to do a load test on the battery. If all is well, will attempt the residual drain test.

I've never known such a difficult battery to remove from a car, what a ridiculously sized compartment.
