AA battery testing

This is a cheap way to test your AA batteries to see if they are charged. Wonder if it would work with lead acid batteries?

    The tongue test will work on a 9V battery like for smoke alarms.
    I imagine it would work on a car battery, if your tongue is long enough.

  • AGMs might not make such a mess. I don't think camperpaul clicked the clicky.
  • AA (i.2AH) cells should be tested with a one Amp load.

    Scale it from there.
