Testing, Charging And Monitoring A Single Cell of NIMH

Found this....

Or the TI version . . .

look at the LTC4060, LTC4010, LTC4011

at www.linear.com

They have app notes and design examples

Is this maybe homework? Then you already have your answer(s)!

If not, all I can say is that usually today, you just buy an intelligent charger that will "look after" the cell properly. They are so cheap nowadays...

no i don't have a circuit - a tester might stand for multimeter ... highly sophisticated specialized lab apparatus intended for speciffic capacity and model (e.g what time it is on earth?)

if you need to reject a black lamb from a set - you should probably charge and discharge the items - the higher internal resistance units tend to get less charge if charged as a cell-pack - t.m. your starting conditions vary by cell not meaning the low voltage items should rejected without futher testing - if you have enough of the cells in hand you can regroup similars by test result ...

you have to keep count on coulombs that enter (-thermally escaped = ) coulombs that exit (-thermally escaped) + to adequately evaluate this you need T(°C/K/e.c),U(V),Q(C),"operational age of battery"(hours?/charge discharge cycles?/el-luthe condition?) map in hand for your specific cell

the grid would vary on your budget and setup - why don't image search for "NiMH lab" or alike
