batteries - At what voltage is a NiMH battery empty?

WebbA NiMH cell has a voltage of ~1.4 when fully charged, and 1.2 V when 5% to 95% charged. When a cell is nearly empty, the voltage rapidly drops below 1.1 V. Ideally, you should stop using a NiMH cell as soon it reaches 0.8-1V. Allowing it to discharge further will lead to damage. Webb9 aug. 2024 · When the NiMH discharge voltage is lower than 1.1V, its power decreases rapidly. So in practice, we usually set the cutoff voltage of RC cars running NiMH to 0.9V.

Webb10 nov. 2024 · There is no match between the NiMH battery and the NiCd battery for battery capacity. It is usual that the NiMH battery has twice or almost thrice the capacity of the NiCd battery. This happens only because of the energy density of the NiMH battery. In that case, you will get a much better battery backup from a same-sized NiMH battery. Webb18 apr. 2015 · So open circuit and loaded voltage are almost the same then. When loaded a bit, a high impedance battery will quickly drop its voltage even if it's got capacity left, where a low impedance battery won't break a sweat. As you increase the load, difference between open circuit and loaded voltage will increase too, more so for high-impedance ...

Webb9 jan. 2014 · The loaded voltage is less than the resting voltage and the charging voltage is greater than the resting voltage.
