The TS-440 shop manual skips over the battery. Its located on the
control unit behind the front panel, under the shield (loosen the shield
screws before you tilt the front panel down). When I replaced the
battery in my dad's 440 several years ago (it was dead), I bought a PC
board mount cell from Mouser or Digi-Key that was set up to make the
battery lay flat to the board, then straightened out the pins to span
the gap between the original battery mounting posts. Dropped right in.
Be sure that the soldering iron is fully insulated from ground. The
safest way is to unplug the cord on a hot iron and do the job before it
cools.
