Reply To: Intermittent Data to SD Card

Have you replaced the battery pack with another, fully-charged one?  Sometimes when they are going bad (the metal under the battery’s plastic wrapper rusts after a few years in enclosures with condensation issues) they can cause intermittent power outages, which are sometimes hard to detect if your solar panel is capable of supplying enough power without the battery (which is usually the case for CTD-only stations without cellular boards on sunny days).  Sometimes an old microSD card socket can cause intermittent issues with recording data too, so you could try removing it and putting a new card in the on-board, horizontal microSD socket and see if that helps.
