Suggest a 100K thats 33 ua and at least 10 to 60 X more then the memory draws. Memories in standby draw 1 ua or even far less these days. The fact that the battery is at 3.44 and 3.2 suggests it may be fine. I just repaired the front panel of a sig gen and the diode was shorted draining the battery to zero because it was feeding lots of other stuff. Gud luc Paul WB8TSL
