You are correct, i replace my battery i bought it at interstate battery, its a panasonic VL2020 rechargeable, the battery is spot welded to the connector
not soldered when you remove the connector from the battery you wont be able to spot weld it back it requires a spot welding machine very expensive
here is the alternative like the first thread said desolder the old connector with the battery, remove the old battery then solder the new connector with battery to the board, easy fix
