Hey folks, just the latest woe.

My battery is only lasting a few days when I don't drive the car.

I've checked the current across the fuses and the courtesy lights circuit is showing 0.46 amps (all doors closed, all lights off. I've also checked both the glove-box and boot lights at the time and both were off.)

I understand this circuit also runs the smartlock but that's where my knowledge ends. Any ideas?

Car is an ED Sprint xr8

How old is the battery? When a battery is unable to hold its charge, that's a good indication that its about to die or that the alternator is not charging it.

Has a radio been fitted lately- wiring ?
Can you hear anything clicking if you disconnect and reconnect battery terminal
Check current draw at battery terminals
