Maintenance and repair of the swinglet CAM
Caution: If any of the cells of your battery pack are overly discharged
the battery may be irreversibly damaged and becomes dangerous to
charge. If the battery grows beyond its regular size or if any of the
cells are punctured it is also likely damaged and should be discarded.
Forcefully charging a damaged battery may lead it to take fire. Do
not attempt to charge an over-discharged or damaged battery.
Dispose of the battery safely.
