Thank you for the pictures. A possible substitute that I saw was the battery for a Navigon Pocket Loox N100. This battery has 4 terminals and all we have to do is to solder the terminal to the board via jumper wires. Also another potential Navigon replacement with wires already attached.
I may have misled by saying the circuit board was stuffed into the foam. That was my first thought, but now I realize that’s based on nothing. The circuit board may cover the whole back of the battery. We won’t know enough until someone disassembles the battery, or at least tries to take off the black tape-like covering off the back (the side with the circuit board). And we know there are always warnings about disassembling a battery.
Even if the circuit board is just stuffed a little into the white foam-looking stuff, a slight poking with a ballpoint pen revealed that its texture is like the toughest type of condensed foam, and the penpoint didn’t dent it. Assuming it’s just stuffed a little bit into the foam, it needs to be in there for structural rigidity and positioning (the contacts have to mate with contacts in the front half of the Connect). Then how could we mount the circuit board in the new Loox battery without partial disassembly of that battery? What if its insides don’t resemble the foam-like substance I see? Alternatively, we could find a less tall battery and physically attach the circuit board to the Connect’s case, above the batttery, for rigidity and positioning.
On the battery site you linked there was a box on the right that said something like “Tell us why you didn’t buy from us” and I said we were looking for a Connect battery, gave the Flickr link, and my e-mail address. I’m not hopeful, but maybe…
Glad we’re doing this investigation into a battery replacement. But it’s not looking good.
