Hi all...first post here but I've been an occasional lurker for a number of years.
I'm working with a Cent I/Partner 0 that needs to have the CMOS battery replaced. The battery is easy enough to find, it's the installation that I'm asking about. I've done electronic soldering before (DIY automotive exhaust gas sensor controller) but that project was much, much cheaper and much, much easier to rectify if I made a mistake. The work on this machine is intimidating me for some reason. I suppose it's the awkward soldering position, cost/scarcity of replacement parts, and/or effort to fix if it goes awry. So, I had a thought that might be good or might be stupid and I'd like you (collectively) to be the judge.
Rather than desoldering the old battery from the mobo, would it be acceptable to cut the legs of the old battery right next to the canister and solder the new battery legs to the old legs still sticking out of the mobo? It seems, to me, that this would cause less heat conduction into the motherboard itself, reducing the chance of doing permanent damage.
Am I just being a pansy and it's not that easy to damage the mobo? Or, are the warnings, indeed, justified and maybe this a good idea?
Thank you for any advice,
