HP-50G Excessive Battery Drain / Fix?

[Tugdual]

The 50g is well known for short battery life and I rapidly purchased low self discharge batteries. Not an ideal solution since the 50g also expects a pretty high voltage. I drained batteries in 3 weeks after acquisition. 1 week is really short time unless you used it intensively. This being said you're the first one suspecting a flaw and I'm curious to see if this leads anywhere. I myself have no clue.
