I was trying my electrical tester the other day, and discovered that I had managed to forget to turn it off again.So, I decided to hunt for rechargeable batteries.Alkaline batteries: 1.5V cells, 9V made from 6 cells, or about 9V.NiMH, 1.25V cells, One could make 9V from 7 cells, or about 8.75V.NiCad 1.25V cells, One could make 9V from 7 cells, or about 8.75V.Lithium Ion, 3.6V cells (or so),Most of the 9V Lithium batteries I'm seeing are about 7.2V to 7.8V (2 cells). I would have probably done 3 cells, or about 10.8V.Anyway, how important are the voltages? A little high? A little low?
