I run a Garmin 350c with a 5 inch screen so it will use more power, i also run a han held Garmin gps 12. I use the dead battery from the Commy and it sits from 11.5 -10 v then I charge. I get 13-15 hour from it running from 11.5 down to 10v.

No good for a good battery but this thing won't go above 11.7 v for some reason.
