RE: New 1100 mAh A123 available everywhere and no word here!
Unfortunately on the first pack I opened up one of the tabs connecting to the batteries was broken off when I opened the package. It's possible that you would never know it using the battery in a tool since things were packed together in there pretty tightly, but when I pulled things apart the tab was hanging free. I didn't realize at first that it was supposed to be soldered/welded on!
