Thermally Controlled Nicad Charger

One method to charge Nikel Cadmium (NiCad) batteries quickly with out abuse is generally to measure battery cell temperature and taper the charge accordingly. This nicad charger circuit works with a thermocouple for this function. Another thermocouple nulls out the effects of ambient temperature. The temperature difference between both thermocouples can determine the voltage, which […]

Check the milli-Ampere-hour capacitance of your rechargeable NiCad batteries

Introduction With this mAh meter you can check the mAh capacitance of your NiCad or NiMH rechargeable batteries Normally the cheaper NiCad AA-type cells have a capacitance of 500-750mAh (NiCAD) the more expensive NiMH AA-cells types are up to 1800mAh. I built this circuit because the capacitance of some of my older NiCad batteries seemed […]
