Hi I bought 7 off these in 05 off ebay, picked them up from a guy near reading, his story is that they have been used as a backup in large security systems incase of mains failure. Claimed they were only a few years old, but I subsequently found a date stamp which made them about 7 years old.
They were half knackered, gave about half their rated output before the telly switched off (low voltage alarm on the inverter) :Sad: As John says for the price, (I think I paid £25 each) you can't expect to much, but with all the buggering about fitting them, then dumping them after a year and fitting some new ones, I wish I had bought new in the first place.
:Cool: Seeing as we are only using Solar power to re-charge the batteries. I think they don't do too bad. We manage to watch TV during Breakfast, Lunch, Dinner and of course 4 hours in the evening plus the standard lights and other 12v bits and bobs. Even during this time of the year. Perhaps not possible in the UK though?
