There's a lot of mentions regarding essentially jumpstarting the dead battery cell (the 3 18650's soldered together) on the Theragun Elite, but I'm seeing a lot of conflicting info online where it's not recommended to do something like that due to the fact that if the batteries have discharged to a level where they cannot hold a charge, the chemical changes the battery undergoes makes it dangerous to revive. That is, fire/explosion risks. Anybody more experienced with batteries/18650's that can shine a light on this? Debating if it's worth it to perform something like this or to get new batteries altogether.
