I built a NIMH battery charger with MAXIM 712. It was used to charge 4 AA cells in fast charging mode but I found out the problem with the charger is that it terminate charging process too early, most of the time it stops charging after 15min-1 hr, which is quite early compared with 2 hrs designed period ( I using 4 AA 2000-2500mAH, 1.2 V cells, charging at 0.5C ). I realize this when last time I used it to charge 4 camp lanterns. Really puzzled. . . Can somebody give me some advice??? I just thought that may be the problem is on MAXIM ( though I knew this IC is recommended one...)
