So, the battery should indicate that when you fill it it'll perform a wipe to block zero. I was on my highest yet run, had about 8 mil active prestige but like 30 mil I was about to claim, and figured I'd do the battery first. Bad move.
Maybe I'm just stupid and it was obvious. But it still sucked.
 "Block Fuser"){kind=icon}
 "Cube Escape: Birthday"){kind=icon}
Sorry about that, I will update the information tooltip.
