Aa Battery Charger Output Voltage

What should be the volt and amp rating of the charger for say 3 7v 800mah 3 7wh li ion battery.

Aa battery charger output voltage. If a aa battery or any other has a normal voltage of 1 2v the charger voltage must be at least 1 2v. Also if i have another battery 3 6v 6200mah 2 3wh li ion what would be the best common charger for charging both batteries. An alkaline battery really only outputs a 1 5 v voltage at the very beginning of its use. A regular aa battery which is a an alkaline battery has a 1 5 nominal voltage charge but when it is fresh or brand new it will have 1 65 volts.

Aa batteries are typically dry cells which are made with an electrolyte that is inside a paste. Ebl presents aa aaa battery charger with pack of 8 rechargeable batteries 2800mah. That is the full capacity of an alkaline battery but when it reach about 1 4 volts it will be considered dead. Soon after it begins to decrease down to well below 1 2 v bottoming out around 0 6 v.

This will prepare the tool to test your battery charger which supplies dc or direct current power. An electrolyte is a solution that conducts electricity. Twist the dial until the pointer enters the dc range stopping on the next highest setting to the voltage of the charger you ll be measuring.

Buy now from amazon ebl provides you the most powerful aa battery charger that gives an output current of 2800mah.

To test a standard aa battery which is about 1 5 volts you would use the 2 dcv setting. When under a load a thin rod inside of the battery reacts with the paste to produce a voltage. Actual measured voltage of the 2 series batteries while charging is 2 885 volts with a current of 240ma. Because of this the average output of an alkaline battery is the same as that of an nimh rechargeable battery.

The specs for the charger current for these three types of batteries is 200ma with 2 batteries in series at a voltage of 2 8v.
