That was one of the first things that I tried (with the same result). But I don't want to be a major PIA so I kept it for me. It's enough that my HP-25 LP keeps draining it's batteries from time to time with no apparent reason.

I don't have a HP-25 LP GPS version at the moment here. But I will build one end of this week and will check the speed km/h knots problem.

Can you measure the current drain in sleep mode? It should be around 100 uA. I have feedback from other LP owners, which report, that the battery is working now for weeks. But leaving the ACT chip drains 4 mA current. It has to be removed or its power lines cut. This was not mentioned in the manual, because I didn't know it.
