How many mAh is a 1.5 Duracell AA battery?
This means that you may not be able to predict how long your electronic device will run just by looking at the capacity rating of a battery. For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 1,900 mAh.
How many amps does 8 AA battery have?
If the 8 AA batteries (2.8 ampere-hour each) are connected in series, then the electric current flowing = (2.8 ampere-hour) / (20 hour) = 0.14 ampere.
How do you know if a rechargeable battery is bad?
Connect the positive battery terminal to the positive voltmeter end. Connect the negative battery terminal to the negative voltmeter end. The voltmeter will test the battery strength, but the test should be repeated after the battery has been used a bit.
