Those Red/Yellow/Green 3-LED Battery Level Indicator Voltage State Of Charge
Would anyone know where to purchase the small 3-LED battery indicators
seen on flashlights or other battery powered items which indicate the
condition of the battery?
There is a very compact side-by-side rectangular red, yellow, green
3-LED indicator on some products to show when the battery charge is
** No way it will work with rechargeable cells like NiCd or NiMH.
Only good for non-rechargeable like alkaline.
This is contrary to my expectation. Please enlighten...
** Simple fact is that no voltmeter reading will show the state of charge of
a NiCd or NiMH battery.
The discharge curve of the cells is almost flat - ie the terminal voltage
does not vary until the cell is nearly exhausted.
This is quite unlike non rechargeable cells like carbon zinc and alkaline.
