My 2009 1.4 petrol i30 has suffered from a flat battery recently after a few days of non-use. I bought a new battery to replace the original factory-fitted Solite, but I wanted to be sure that it was the battery at fault and not excessive drain from a fault in the electrics. So, with everything switched off (ignition key out of the socket) I measured the current drawn from the battery and was surprised to get a reading of 170mA.

I then withdrew the memory fuse and measured the current drawn at 2mA.

Is a quiescent current of 170mA normal? If so, then a week of non-use would drain over half of the battery capacity.
Can anyone shed any light on this?

Hi Richard111

 

How long did you wait from key off until you measured the draw..?  I did same test on my 2008 a few years ago and seem to remember there is higher draw for about 10-15 min before it goes to sleep.

From taking the key out of the ignition and locking the doors, I waited 30 mins before disconnecting the negative lead from the battery and inserting the meter in series. It gave me the same reading (170mA) as yesterday when I simply took the key out of the ignition and took the measurement straight away.
