The battery pack on the S.701 SevenStar SART should be changed every 5
years, or if the unit has been accidentally damaged or activated (a
brief period is allowed periodically for annual testing.) The S.701 was
the first SART that can be shipped
as non-hazardous goods*, and the
replacement battery pack was also able to be shipped as non-hazardous
goods for many years*. (*Please check with Sartech for the latest
replacement battery pack kit is available from our distributors, and is
capable of being fitted by a competent service engineer with only a
2.5mm hex driver. The kit includes a new gasket, screw and O-ring, as
shown in the photo.
The S.701 from SevenStar is also
unique in that the SART
electronics remain totally sealed
during battery pack removal and refitting - it is impossible to damage
or de-tune the electronics, or allow the accidental ingress of moisture.
