66ST batteries

[+Berta Nick Zoey]

I want to replace the battery pack that came with my 6ST.  The batteries seem to wear out faster than when I bought the unit 3-4 years ago.  I do realize that there is a button under the batteries that must be depressed in order for the batteries to charge in the unit.   There are tricks for that that I will try.  The battery pack says 2.4 volts and 2000 mH.  Is it save to assume that the 2.4 volts is two 1.2 volt batteries together?   Also, I am thinking that if i want to go higher in the mH rating, that is safe, correct?

Yes,  completely safe. 

 

2000mAh batteries will provide less run time with a longer charge cycle lifetime compared to 2400mAh batteries.
