Dear friends i have a 12v, 2ah NiMh battery. i have to make a proper charger circuit for that one. i have tried some circuits, but only find my battery heating up not charging. Can anyone help me to solve this out.
 

The Ni-MH battery has a nominal 1.2V/cell and fully charge of 1.4V/cell. If your battery has 10 cells, you can use a charger charge with a 14.4V max and 200mA (1/10 of the battery's AH) for 12-14 hours and discharge the battery with 200mA load until its voltage drop to 11V check the discharge time in hour and multiply by 10 that will be the approximate % of the battery capacity remain.
