Nimh battery discharge rate
Webbthe battery that is equal to the ESR multiplied times the current squared (P = I 2 X R). This can result in significant heating within the battery at high rates of discharge. Both Ni-Cd and Ni-MH batteries have extremely low ESR values (well below 0.1Ω for a typical "AA" cell), which means that ESR is almost never a limitation for peak discharge WebbThe typical specified battery voltage in data specifications for NiMH batteries is 1.2 V. The typical discharge curve of both nickel and alkaline batteries is a non-linearcurve from 1.5 V down to 0.9 V (with some battery capacity remaining when the battery voltage is …

Webb4 okt. 2024 · Ideally, you should charge your NiMH battery at 1.2 volts per cell. So, if you have a four-cell NiMH battery, you would charge it at 4.8 volts. To get this voltage, you can either use a special NiMH charger or a standard household AA or AAA battery charger (as long as it has an adjustable voltage). WebbThe NiMH battery also has high self-discharge and can lose up to 20 % of its charge during the first 24 hours and thereafter 10 % per month. Like NiCd batteries, they have a nominal voltage of 1.2V per cell with a typical end-of-discharge voltage of 1V. The total voltage of the redox reaction is E 0 = 0.49V – ( – 0.83V) = 1.32V.
