Practically every single nickel-cadmium battery in use today could be charged using the following universal adjustable Ni-Cad battery charger circuit. For batteries with a capacity ranging from 50 mA/h to 2500 mA/h, the rate at which they are charged can be adjusted through a rotary switch. It promptly adapts to any battery voltage up to 20 volts.
NiCd batteries should ideally be charged using a constant current source. Unlike lithium-ion or lead-acid batteries, the voltage for NiCd charging is variable and can rise throughout the charging process. The recommended charging rate is around C/10 (10% of the battery’s capacity per hour).
The cheapest way to charge a nickel metal hydride battery is to charge at C/10 or below (10% of the rated capacity per hour). So a 100 mAH battery would be charged at 10 mA for 15 hours. This method does not require an end-of-charge sensor and ensures a full charge.
In a standby mode you might want to keep a nickel metal hydride battery topped up without damaging the battery. This can be done safely at a current of between 0.03 C and .05 C. The voltage required for this is dependent on temperature, so be sure to regulate the current in the charger.
When it comes to getting the most out of your nickel-cadmium (NiCd) batteries, proper maintenance and care are crucial. By following a few simple tips, you can ensure that your NiCd batteries perform optimally and have a longer lifespan. It is important to store NiCd batteries in a cool and dry place.
Nickel-cadmium batteries may be overcharged at the right ampere/hour rate without suffering any harm. Since no damage will result from leaving the device on charge for 48 hours, a prolonged charging using a 10% ampere/hour charging rate has been adopted.

NiMH battery technology, how to charge Nickel Metal Hydride Batteries …
Whereas with lithium ion and lead acid batteries you can control overcharge by just setting a maximum charge voltage, the nickel based batteries don''t have a "float charge" voltage. So the charging is based on forcing current through the battery. The voltage to do this is not fixed in stone like it is for the other batteries.

$begingroup$ I can confirm that "jump starting" from a bench power supply works for NiMH batteries. Here''s what I have tried with AA and AAA NiMH cells: set a bench power supply to a max. current of 1 A and 0 V. Connect the battery. Increase the voltage until the current maxes out at 1 A. After a short time, the current will decrease to some ...
