PE 6300 Perc 2 controller replacment 44TXF Compatability?

Ok, lets try this again with out the service tag...

I purchased a used 6300 off of ebay and was setting up a sharepoint site with it for my kids lego team at school.

The perc2 controller went down on a battery fault. I had a couple other perc2 controllers, and got system running on one of them.

Problem is that the two I had, the batteries looked worse than the one I put in the server originally. I am thinking I am going to have the same problem very shortly.

I was looking for a page that showed how to do a solder replacement and what batteries to by to do the replacement my self, but did not find anything. Does anyone know?

Also I was looking on ebay for additional controllers, and found a 44TXF perc2 controller, that appears to be a later design, with a replaceable battery pack.

This looks like a good solution to the problem, but is the 44TXF compatible with the 6300? I found a site that said it was compatible with a 6400.
