Replacing rechargeable cells in a Rockwell

Hello all. I opened a Rockwell "The 24K" and found the 3 internal cells surrounded with a little white shiny cristalline stuff, nothing bad but the machine no longer works standalone of course. These cells have a specific size, much larger than 'coin' batteries, and are soldered in series. Do you know what model I should ask for ? European-style references would be appreciated. Thanks in advance.
