Been using my HDS 7 for ice fishing. Have 2 batteries a 7 and an 8 amp. Only get 2 to 3 hours out of each batteries. Is there a way to disable the GPS and cut down on the power usage…or would that make any difference. Have looked at small ATV batteries, but could not find any sealed ones. I have looked at other fishfinders and may go that way if I have to..(both batteries test 13 – 14 volt storage).

I tried with a gen 1 HDS5 and couldn’t find a way to stop the GPS and keep the sonar running. Not saying there isn’t a way, just saying that I didn’t find one after playing around with it for awhile.
Screen brightness is the biggest variable in battery life with the LCDs. Keep it as low as possible.
I have no problem getting a full day out of my HDS5 on 1 cheap 10ah battery.
google ” doctor sonar” hes a genius
Not sure this is going to do it for you but maybe give it a try
On chart page, hit menu twice.
go up to setting, arrow right
go down to satelites.
If it’s is highlighted auto HDS 7 hit enter and it should become un highlighted.
I am thinking that shuts down the GPS side of unit but am
not for certain.
I’ll keep playing with as time permits.
Hoping others chime in.
Good luck
