Can someone check my logic here, please? Sorry to start another aux battery
thread, but I have to put cash on the barrel tomorrow, so...

There is a comparison chart of Optima deep-cycle batteries at...

http://www.dcbattery.com/optima_yellow.html

... and I think the only difference is that the 750-U has posts on both the
top and side, while the 750-S has only one set of posts?

I'm buying one tomorrow. Is there a preference for the bus owner between
these two models? The power output seems to be identical.

Also, can anyone give me a ballpark estimate of how long the deep-cycle is
good for between charges? That is, if I go camping for a week (in one spot),
how many total hours (about) can I expect to get from the battery for cabin
lights, CD-player, stereo, etc. before the thing goes dead?

Thanks for any help!
