Do they use the same CMOS battery?

Unfortunately, no. Here's a picture of them together: http://www.kawakami-ca.com/images/02k65 ... 2k6715.jpg

While the polarity of the two battery connectors are the same, the physical dimensions are different (600 series is thinner than the X2x).

I noticed that ebay separated them but they surely looked alike. Thanks for the info.

The polarity and connector size is different:

Odd that they would use three different connectors on what appears to be the same battery although polarity could be a factor.

Designers must not talk to each other.
