Replacing Battery on VFX (non-SD)

Replacing Battery on VFX (non-SD)

2006-07-05 by justin_s_pope

I found a compatible (CR2032) lithium at RadioShack, but I can't tell 
(or get the board out to tell) which of the two connectors is which on 
the board (+ and -).  I tried downloading the .tif schematics from 
the "files" section on here, but all of them seem to be "damaged" 
according to my computer.  The battery connection on the board looks 
like this when looking at it from above:

  *  (     )  *

the space in the middle is for the battery, obviously, but which of 
the two slots are which?  I unfortunately had to ruin the connector 
desoldering the batter, and I was going to try and re-solder a new one 
in with wires just to get it up and running again.

Any help?

a "button cell" has its + side as the main casing
the underneath is the - side

so they almost always sit + up based on the physical casing method

I got that, but idiot me forgot to look at how the old one was connected 
before attacking it with desoldering braid and breaking the old battery 
connector! :-(   what I want to know is, there are two contact points on 
the board to which the battery connector's terminals were soldered.  
Does it matter which is which so long as the + wire doesn't touch the - 
one?  Can't I just solder (carefully) hookup wire to the new battery, re-
solder each wire to one of the contact points and call it a day?  Or is 
one specifically routed to the + signal?
