X51V Backup battery does not match
I need to change my backup battery in my X51V, so I ordered one, ordered the extra small torx #5, and proceeded to open the case. Much to my surprise, the backup battery inside was a soldered in job that looks like a small watch battery. So I asked the company that sold me the backup battery (a little green thing with small leads and a nano plug) if the new battery could be adapted somehow. They said that the X51V had both kinds of backup batteries and that I could adapt it in place of the soldered in one, but did not give any further information.
Has anyone run into this? I am thinking that I should cut off the connector and solder the leads in place of the current battery. I don't know what the proper polarity should be. Perhaps if I connect the charger cable with the case open, I can pick up a voltage off of the leads, and then assume that the red one on the replacement is the positive.
Suggestions?
