Voltage of a NiCd cell when being trickle charged?

[treez]

What is the voltage of a NiCd cell when it has charged up fully and is being trickle charged?

I presume that it is less than 1.6V?

Could you give an answer for any temperature, and if possible also,

20 degC
10 degC
5 degC
0 degC
-5 degC
-10 degC

Hi Treez,

How are you? You're still tied to NiCd.

I dont have exact voltage values for exact environment temperature but you can se this :

The safe temperature range when in use is between −20°C and 45°C. During charging, the battery temperature typically stays low, around 0°C (the charging reaction absorbs heat), but as the battery nears full charge the temperature will rise to 45–50°C. Some battery chargers detect this temperature increase to cut off charging and prevent over-charging.

A Ni–Cd battery requires a charger with a slightly different voltage than for a lead–acid battery, especially if the battery has 11 or 12 cells. Also a charge termination method is needed if a fast charger is used. Often battery packs have a thermal cut-off inside that feeds back to the charger telling it to stop the charging once the battery has heated up and/or a voltage peaking sensing circuit. At room temperature during normal charge conditions the cell voltage increases from an initial 1.2 V to an end-point of about 1.45 V. The rate of rise increases markedly as the cell approaches full charge. The end-point voltage decreases slightly with increasing temperature.
