Wont power up

Hi, im new here and i have a question.

My Pocket Windows phone's battery has gone completly flat feor around half a year now. It will no longer charge or power up.

My pda is a HTC PM200 and has a PM16A battery (quite a few pdas share this battery).

It has 6 terminals and none are marked with a + or a -.

I have a power adapter wih a changable voltage with a plus and minus wire.

What terminals on the battery should i connect this power adapter to give it a boost of enery so i can make sure the pda still works?

Thanks
Mike

That battery will be useless, and will need replacing.
