Using NiMH batteries for the BT3554-50
QCan I use NiMH (nickel metal hydride ) batteries to power the BT3554-50?
Technically, you can.
However, the BT3554-50 was designed to operate with alkaline batteries, so there will be large discrepancies on the battery level indicator because of the different discharge characteristics between NiMH and alkaline batteries.
The indicator operates based on the characteristics of alkaline batteries. Therefore, the unit may shut off suddenly even if the power indicator shows sufficient battery life when you use NiMH batteries.
