The SWELFOCUS has no clutch so if the battery does go flat, you either need to remove it in the dark or change the battery. Some early models had a problem with battery drain even when not in use. You may read about this in reviews. I purchased mine in 2014 and have had no such problems.
The battery life depends very much whether you have parfocalized eyepieces or not. If you are using it a lot to move the focusseer in and out, then obviously you wont get the same life from the battery as if you are only doing fine refocusing. If you find you are not getting the battery life you'd like, hooking in an external supply from your 12V scope supply via a DC-DC converter would be very simple.

Thanks Joe
I like the idea of getting everything running ooff the 12 batteries. I have not tried to work out power needs, but I will have a guess. A remote opperation would need a lot of power. Anyways one step at a time.
I always have a large supply of 9 vlt batteries ..they are the ones that power my mini amp for my cigar box guitar... so thats good.
I think I have I little solar panel that would charge one of them...
Must see what one of those little panels can do to top up a battery...be a slow trickle thats for sure...which may not be a bad thing.
