Battery health and Rosalina

Hello all, I had asked this question in the homebrew Discord yesterday but it appears it got buried, and I wasn't sure if the question would be allowed in r/3dshacks.

My question, I use one of those third-party grips for my New 3ds XL, because of carpal tunnel, and with it I can't see the back panel so easily without taking the console out, would the info that Rosalina gives for the battery give any indication that the battery is starting to go bad? My 3ds still has the original battery from the factory and it was purchased about 10 years ago. I do know that it discharging faster than normal can be a sign of bad battery health, but that isn't currently happening. Would there be any other indicators besides the faster-than-normal discharging or it starting to inflate?
