Charge Curve
This charger can charge between 8 and 15 NiMH or NiCd
cells connected in series and will detect and provide the
correct output voltage and current to suit.
End charge is by -Δ V (about 5mV for each cell) detection,
after -Δ V. It will turn to trickle-off charge, it’s charger
current is fast charging current of 1/20.
