That was very helpful and informative reply. I did see that the yellow LED doesn’t quite go out but faints (equivalent of ‘off’) after charging
the battery using microUSB cable. It took almost 12 hours which is what I originally figured. For anyone who comes across this thread in future, a word of advice: choose your battery wisely. You may not need a very big battery.
