Hi Barry,
The batteries or their cases in different aeras of SDS7 had many shapes. Your round cylinder IS the battery itself, not a case. The shrink wrap is for preventing shortcuts.
You don't need to unwrap anything, desolder and remove it complete. Sometimes the battery is fixed to the board with doublesided tape or glue, so you might need some force. It doesn't matter if your new battery has another shape as the original, only voltage and polarity is important. I like to replace the batteries with 3 x 1.2V mignon size wired serial, because they are cheap and have a big capacity (if the owner wants to switch off his SDS7 for another 20 years...).
So: Good luck!
Michael
