i’ve got a new gizmo that runns off a li-ion battery, and i’m trying to figure out if its charging up fully.
i have an old analog multimeter, my digital one seems to have packed up, and i can’t really use either.
the stated battery power is 7.4v 2200 mAh
i’ve put said meter on 10v DC and get a little over 3 in the 10 ac/dc scale (you can no-doubt tell from my explaning that i’m way out my depth).
i thought i’d be clever and test some other batteries to use as a guage to see if i’m measuring correctly… with a fully charged 7.2v 1100 mAh nimh i also get a little more over 3, but then with a new tesco value 9v it goes off the scale so shifted it up to 50dc and i’m getting 25. so i’m guessing i’m doing something wrong!
