Lithium Batteries and Our GPSMAP "X" Series Units

Not all lithium AA batteries will work with our GPSMAP® 60 and 76 "x-series" devices as they have too high of an output voltage. Typical AA batteries have a voltage of 1.5v each. Some lithium AA batteries put out 1.65v or higher. Our units will only accept power from batteries that output less than 1.65v.

If using lithium batteries and the GPS will not power on or will shut down quickly after being powered on, the high voltage could be the issue. They will need to be drained a little to be in the operative range in the unit. Use a flashlight or other device that uses AA batteries to drain some power from the batteries.
