I do not don't recommend it, although it might work. But it will heat up the battery and you must avoid by all means that solder flows around the edge of the battery and shortens it. When I once tried it the coin cell exploded in my fingers and since that time I know what tinnitus is. You might find the leaded cmos battery as a spare part or maybe you have a dealer around who has the equipment to weld leads to a coin cell. (we have such a dealer 30km away). Another possibility: maybe you have enough room to insert a battery holder somewhere in the computer? 73! de Werner OE9FWV -- I made a mental note and now I can't remember where I put it!
