At What Voltage Should A Aa Battery Be Replaced. Load the battery with about 6 ohm resistor that will load the batter by somewhat 250 mA somewhat like a bike light would draw. Now the device expects 30V from alkalines but you give it only 24V from NiMH.
A regular AA battery is a an alkaline battery has a 15 nominal voltage charge but when it is fresh or brand new it will have165 volts. This is usually for 515 seconds and should leave a battery sitting at 1265v approximately. What Voltages Indicates Bad For AA AAA Battery.
The ideal car battery voltage with the engine running is between 137 and 147V.
If the battery isnt fully charged it will diminish to 124V at 75 12V when its only operating at 25 and down to 119V when its completely discharged. In most areas members can call the AAA Mobile Battery Service to have a battery tested and replaced if necessary at their home or work. Now the differences are much more likely to manifest. The basic fact to remember before you check the battery is that the proper voltage for AAAAA alkaline battery is 15V and the proper voltage for AA rechargeable battery is 125 Volts.
