I have a Soundtrap ST4300 that was deployed in the marine environment for an extended period of time such that both the SD Card was full and the battery fully consumed (0% remaining). When plugged into the computer & opened in the Soundtrap Host software, I received a warning that the battery was too low and the device must be recharged for a bit before use (so, let it be and then refresh in the host software). After sitting for >1day, the device did not charge and I cannot access the data.
Are there alternative ways to charge the battery? Are there tips/tricks to preventing (or minimizing) battery deterioration? (The batteries on these devices are internal & not readily replaceable).
