My SC60w
- AW 2600 didn't make reliable contact. Sometime it would work sometimes not. Poor positive contact and Tail spring would catch and pop on those three nubs on the neg contact.
-AW 2200 button top: works great!
- Redilast 2900: Would not fit in tube. It might work if I remove wrapper but it is noticeably longer than other cells and I don't want to over compress the tail spring so I have not tried.
