@juma_yetu, first point, read better
hmmm.. 3-4 hrs seems too fast.. can i use atx power supply(PSU) instead?
Hehe, that's true But from the size you can assume it's not very power hungry. I agree, not very scientific but will do for hobby standards (and more then you want to know for industry as well...)
If that is a response to my Reply #2, I did not mean 3 or 4 hours. I meant 3 or 4 amp hours - of course if you are drawing 1 amp from the battery it amounts to the same thing. Unfortunately battery manufacturers are very optimistic....R
You have already mentioned this battery in your other thread.https://forum.arduino.cc/index.php?topic=541078.0You could have asked it there.
how can i charge the battery if its attach in the barrel jack of arduino?
