[QUOTE="AuMan, post: 651389, member: 2670"] When you say it measures 7.8v, is this using the battery check function in the gpx menu , or using a multimeter in the battery plug? If using a miltimeter you need to check pins 1 and 4. Pin 5 is the charge input and will show a lower voltage than what is in the battery. The battery should reach between 8.2 and 8.4v when fully charged. If the strip behind the rear panel of the gpx has been damaged due to the power plug wearing out, this can cause the detector to read lower voltage than is actually in the battery and for the low battery alarm to come on before it should. Can you test your battery on another machine or you borrow a known working battery? How long is your battery lasting from fully charged till the low battery alarm sounds? Cheers Mick [/QUOTE]
