The amount of negative current gets less negative (more positive), ie less discharge, with time. Thats why it goes up!!
Depends on your perspective

Just saying because some people might have expected to see the line dropping after switch-off.
(which it does in value)

Still working
#20: Re: Battery Discharging Problem Author: V9977, Location: Athens, GreecePosted: Sat Nov 10, 2012 3:11 pm ---- 7mA is perfectly fine for quiescent current.
Your graph shows very well why battery should not be just disconnected without proper care or with ignition on.
Here it is again so it's visible on this page:

#22: Re: Battery Discharging Problem Author: bezford, Location: darlingtonPosted: Sat Nov 10, 2012 10:20 pm ---- The battery disconnect procedure and the soft reboot both tell to wait 3 mins before messing with the rest of the procedure so it makes good sense when you read the graph....nice one.
it would be interesting to know what is being switched off at each noticeable change/drop on the graph?
