I have converted to using 6V 12amh Gels on my GPRS Trail Cams
Still keep the internal battery bank full with rechargeable AA - as you will need secondary battery backup when you do Gel change over on the MG980 30M units as you have to disconnect the 6v power cable to access the internal menu/on off switch etc.
If you do not have AA batts in the internal - when you pull out the cable it will cause the unit to default back to Factory original setup (date/settings etc) then you need to reload via Puter all the data into it again.
So the 6V is looking like the way to go, long lasting and literally free running.
