If I want to use 2 9v batteries for my circuit, what happens when i run them in parallel?
what i want is increased capacity or mAh rating
now, if these batteries are different, one might drop in voltage faster than the other battery. for example, i might have one 8v battery and the other still might be at 9v. What voltage will the power unit (with the two batteries in parallel) show?
if i still have those two batteries and i wanted to replace one of them, can i take the 8v battery out while the circuit is still on and replace it with a new battery on the fly?
thanks
