The 12.0Wh capacity supports extended operating periods in crane and industrial remote controls where the transmitter stays active for hours. Ni-MH chemistry delivers a flat discharge curve so voltage remains stable until near the end of the cycle. Built-in protection guards against overcharge over-discharge over-voltage and short circuit.
