I'm trying to find out the remaining charging cyles on NiMH AA 1.2V rechargable batteries.
I'm placing a battery in series with a the parallel of 3 resistors of 2.2 ohms which are 5, 10 and 20 watts respectively.
To log the discharge and using an Arduino UNO and with some visual basic code i can see on every second, the voltage values measured (it also shows a graph).
When checking a functional battery it takes 15327 seconds before the curve shows it's discharge and it takes 9000 seconds on the non functional.
I would like to know what parameters i should take into account to know the remaining charging cycles.
Regards,
