Will it work with battery U1R-1T titan battery

Yes, the SP1297 will work with this specific battery

Can I leave this hooked to my car battery all winter long ?

It’s a smart charging unit that recognizes that your battery is fully charged and then reverts to a trickle charge to keep it that way. I haven’t left it on for months but I have left it on for weeks but I wouldn’t be afraid to leave it on for that length of time. I love it because I can charge through my cigarette lighter so it’s really simple to disconnect and go. The directions will tell you how to check your car to see if you can do it that way.
