Guys I have a few of the original VoltWatch units and want to be sure I can use them with nimh batteries. (5 cell AA)
The original Voltwatches were only good for use on 4 cell batteries. The later versions have a switch on them so you can switch between 4 and 5 cell batteries. If you unit has the switch, it will work on either NiCad or NiMh 4 or 5 cell batteries.
