While I am aware of the risk associated with charging Li-ion below 0 °C and that the charge acceptance for a NiMH battery decreases with rising temperature, I am finding conflicting information when it comes to charging NiMH batteries below 0 °C.
Battery University in Table 1 claims that 0°C to 45°C is the charging temp range.
Energizer in Figure 13 claims that the battery will charge at -10°C
Is it possible to charge any NiMH battery below freezing? Is it dependent on the actual battery itself? If it is not able to be charged, why not?
