This is IKEA "feature" 
ZigBee standard states that the battery status is reported in the 0..200 range which is then divided by 2 to get the real percentage. Older IKEA devices report the status directly in the 0..100 range so the division by 2 is disabled in the profile. This is why you get 180% instead of 90%.
