WebMay 13, 2024 · 4. The FT-60 manual says the battery pack is a NiMH pack ("FNB-83 (7.2 V, 1400 mAh)"); so, as we usually use 1.2V as the nominal voltage of a single NiMH cell, a pack of 6 cells in series. You'd usually make sure not to discharge a NiMH below 1.0 – 1.1 V; going deeper can damage the cell. So, the minimal voltage for a pack of 6 in series ... WebMoreover, a flat discharge curve and negative temperature coefficient may cause thermal runaway in voltage-controlled charging. For the aforementioned reasons, in the recent past, Ni-MH batteries have gained prominence over Ni-Cd batteries.
