Hi there,
Theoretically your fully charged battery should last sitting with the draw of 0.02 Amps for a 180 something days. 90Ah / 0.02 Amps =4500 hours / 24 =187.5 days
That's the way it should be assuming your battery is good without any busted cell etc.
Am I right?

Now every day at home started no problem, been away for 6 days and battery dead again? Look like every day driving is okay but leave it for a few days or more and it's dead. I will get a new battery but I suppose that's no good if I have an underlying problem, any advise what/where/ how to check?
