I have the Ovoman K400.

The dashcam setting reset every day, and it asks to pair with phone to be able to save files. I recently figured out how to take it apart and wanted to see what kind of battery it has.

The second photo is the type of coin battery, but unusually smaller than I've seen. I would remove the battery to check the type but there is a weld covering the battery type. The battery is corroded which is why it won't save settings.

Does anyone have information on the type of battery or can assist me with finding a replacement battery? I know I have to do some soldering.
