Hello,
Try to expose their solar panels to direct sunlight (10 or 15 minutes), just to see if they come back to life.

Hope it helps.

You don't. The 30X IIs runs on both solar power and a 2025 lithium battery. If you need to replace the 2025 battery, see this.

Calculator won't turn off with new battery installed.


Hello,
If they are solar powered and if the power down button is not functionning I would not worry about them. Usually battery powered calculators have an automatic power down feature, and sometimes solar powered machines as well. The only free thing we get is the sun's energy. Maybe not the only one (oxygen).
Hope it helps.
