Hi everyone,
I bought some rechargeable 9V NIMH batteries, only problem is my charger can only charge AA and AAA.
They are 200mAh and list the standard charge as 20mA for 16 hours. Do you reckon I could charge these using a lab power supply with current limiting?
Also, for a longer term solution, does anyone have a simple charging circuit that would be suitable? Bonus points if it charges from a solar panel... (I have some spare ones from garden lights)
