This sounds like "top of the line" NiMH batteries from GP.
The discharge curves looks very fine, they are well matched and the cell works fine at any current.
These batteries looks very good and if the specifications are correct they will be some of the top batteries on the market.
But the "free" charger is nothing to talk about.
