An 9 volt square shaped battery is used for all sorts of small powered electronic devices, from fire alarms to kids toys. If you dont have a multimeter or a special tester tool to test your 9 volt battery, you can test it using your tongue. That way you can determine if the 9 volt battery is fully charged or completely dead, using your own judgement tactics. Dont worry about doing this, sticking your tongue on the 9 volt battery is not harmful, you wont get shocked or die from it lol. This is because it hasnt got enough amps and voltage to do so, so lick with full confidence!
1) Stick your tongue out of your mouth.
2) Obtain your 9 volt battery and lick the the two Positive (+) and Negative (-) terminals found on the top.
3) If you feel a little Sting and a Metallic taste on your tongue, on the area you licked it, it indicates that the battery is charged. If you feel no effect what so ever, then the battery is dead and needs replacing with a new one.
