It&#x27;s tricky, metal tabs are soldered right to the battery terminals.  It&#x27;s a lithium battery so you don&#x27;t want to heat it too much so desoldering will be annoying and potentially dangerous.  What you can do instead is cut both tabs to remove the battery then solder wires to the tabs on the board and connect a proper battery holder.  Might need to move the battery outside it since the holder + battery won&#x27;t fit.
