What does the battery icon at the top of the display represent?

It gives a graphic representation of the level of charge in addition to the digital readout.

There is a battery indicator on the main screen when on. The light stays on when plugged in

My guess is that it is trying to tell you the battery is low. Try replacing it.

It will display both batteries and indicate which one is being used by way of displaying the battery icon slowly draining.

I have an indicator, and it shows that the battery is going down. I haven't let it get to the point of running out of power.

It could possibly mean that you are using the wrong type of battery. (li-ion vs NIMH)

It means the battery is already charged. When the battery is charging, the light is red.

Plug it in, put batteries in it, with + and - in designated spots, display shows when it's fully charged.

I am not sure. I am not at home at the moment, but I think that it means that the battery is fully charged and is now working as a maintenance charger. Just keeping the battery at full strength.

language slip. where they wrote "circle" they mean "cycle," as in 50 cycles/sec or 60 Hz."conversion" i'm not sure. my guess is it means "charging.""the board" no clue, my guess is the battery (the item being sold and discussed here)a little native-english speaker editing would help. :)

There is a small screen in the right hand corner. It has a picture indicator that tells you how much battery life it has left.

Most of the time you will see a + sign on the device your putting the battery in. You will also see a + sign on the flat side of the battery. If you see no + sign on the device then it is all most always the spring or metal flex tab that is the + end. If still in doubt try putting the batter in one way and if the device does not work turn it around.

If one can trust the battery images (pics), there is a schematic for F1 terminal ... so I presume its an F1 terminal. Plus, even though you can't zoom on batter picture, it kind of looks like a notched (F1) terminal instead of the F2 terminal.

On the display, the meter shows the battery, with the amount of charge left on it. But it does not give a precise number. You have to estimate it from the simple diagram.

Mine shows the battery on the top left with 100% when fully charged. My LED light also turns green. But I also have my settings to show me how much percentage of battery I have left so maybe that's why??

The battery color pretty much matches the picture accompanying your question. The top is black, the sides are light gray with red writing on one side.

There is a battery symbol in the LED window (top right) that will indicate the charge level.
