Hallo i have some battery problems with second 4500 mAH NiMH battery. The problem is, that full empty robot 581 , (FW version 06 date of manuf. nov 2009) charge battery only 50 minutes than put green lights , even i made minimum 10 time reset ( dock + spot...) , when they charged the battery (is all normal no hot battery only a little warm) and then robot works only aproh 90 minutes ??? But the same robot works 1 year ago till 130 minut with 3000 mAH NIMH battery , and another roobot 781 charge the same battery more than 150 minutes and work 180 minutes, and when i charge battery in the 781 and put to that 581 , at that time also 581 works 170 minutes......
