Rick I have the hg1210 charger as well and usally charge my 3.7v batts at 4.2v setting and my haoba lifepo4 3v at 3.6v setting when use them.Good charger can charge about anything on them.Probably should have charged them 3v uf on it at 3.6v setting but thought I use to charged them on the AG-126 4.2V charger but am wondering if overcharged them what do u think?Do u charge the uf 3v on the 4.2v setting or the 3.6v setting on your HG1210 W?
