I have a 9V 180 ma discharged Nimh battery that I am charging at 25ma.
How long will it take to charge?
Thanks, Andy

** What you have is a 180 mAh battery: h = hour. You do the math....... Phil

Isn't it 180mAh? milliampere hours and not only milliampere?
(180mAh)/(25mA)=7,2h
For nickel based batteries, you normally add 40-50% to compansate for charging efficiency.
