     A: Most batteries are labeled positive (+) and negative (-).
     B: If yours is not, start with the outside contacts.
3. Slide the battery until both pins are touching the battery contacts.
     A: The LCD will light up if it has a good connection.
     B: If not, adjust the pins and try again.

5. "LCD" light indicates a good connection, you have set up the charger correctly for this battery.

7. Now plug the universal battery-only charger into a wall outlet.
8. The "LCD" light will start flashing while the battery is being charged. If it is not flashing it's not charging!
