If the solder joints have been attacked by the alkaline from the cell or battery, it's best to scrape the surface off the old solder (carefully with a suitable knife or small flat bladed screwdriver) before trying to desolder the component(s). Also use some flux to help. Sometimes adding some new solder helps.
