I decided to check my DSi since it’s been a long time, I turned it on and used it. When I open it, I notice a [liquid](https://cdn.discordapp.com/attachments/459906484138934274/1196245153468403783/dsi_leak.jpg?ex=65b6ed1d&is=65a4781d&hm=226d5ccfe7915b350caecae14aeb1211b79e1be1731b30ec860336138fdf4c8c&) at the right side. It had a tiny bit on the left side but nothing connecting the two. I cleaned it with a paper towel and the color was a faint of brown. I haven’t opened the battery yet, but it does not have any sign of liquids coming out of it. The DSi has been in 2 plastic bags for years, closed, and facing up (not tilted or upside down).
What could this liquid be?
