HI,

I am new to the forum and happy to be here.

Just got a Propeak Sigma 2 EQ charger today and read the manual that came with it before start charging my Onyx nimh 7.2 4200mah. I have set it on 3a and Auto Mode. when charging it show on the display 3a/8.1v - 8.9v. Which to me seems pretty high and about 40min it finish and notice liquid start coming out of my battery pack. I guess now it's burn.

Any suggestion on how to charge nimh battery, this would help me very much!

Thanks
