Well, I ordered the 9270 from www.bestconverter.com
today. I ordered a new fuse block with it, too. I decided not to risk any new battery on the old Univolt, and certainly not a new flat screen tv or dvd player on it. We like our gadgets and to protect them I'll change out the converter and buy a decent flooded deep cycle for the time being. I'll learn what I can about care and maintnance of a 12v
system before I spend the big bucks on a battery.
Thanks for the input, I'll be back to this subject if I have any questions on replacing the Univolt.
