Hi Mike---I have the "Hitec Servo Programmer" & cannot keep the on/board battery charged ---After I use it, (nice tool!) which is not very often, & then in a week or two, try to use it again, the battery is completely dead. Have tried different battery...same thing. there is obviously a small current drain with switch off,(batteries will stay charged when removed from unit). Is this normal?---Please advise---
