Battery meters mostly work on terminal VOLTAGE, that is why it is not accurate. It is impossible to charge a battery without applying a higher,
charging level to force current to flow INTO the battery.
C/10 is a normal maximum fast charge for many batteries (avoids Heating, out-gassing issues) (1000mA/10=.1A constant current mode for the PEz)
When you take a battery "Off Charge", the terminal voltage is elevated for a period (load, battery type, temperature,age all affect time), which is why it may show more bars after a short charge.
The charge curve for batteries (and capacitors) is exponential.
It takes
forever (literally) , without resorting to
over charge techniques.
This is the reason and theory behind Astak's
Charge for 12 Hours strong suggestion.
If you make the gauge more granular, it will be
less accurate , because you are trying to linearize an exponential function
