Alkaline AA batteries are rated 1.5 volts, while NiMH AA batteries are rated at 1.2 volts. NiMH generally refers to a battery being rechargeable and to the materials from which the battery is constructed.
How many mA in total when four AA batteries of 1.5 volt is combined? depending on your load resistance what are you using . suppose you are using 100 ohm load resistance than current will flow 1.5*4=6/100=0.06Amp and if you are looking for ba â¦ ttery current capacity than mind it you are using series connection the current will not change remain same as one battery but voltage will change as i mention above 6 volt.
