Apparently they are from the a telephone company. When we tested them we found them to be in excellent shape and since they only cost us about $100 we felt we couldn't go wrong with purchasing them before we knew if they would really work for our system. There are eight in total, each with a 155 Amp hours. Plenty for our little system.
But the big question is... Will they work? According to the websites I've been able to find they are used as a standby system in case the power goes out. Hmmm... They are a sealed battery and supposedly they don't even need to be vented outside. We can't wait to try them out but they will have to wait for a day or so as we have what seems like a million other things to do in the next few days and then with the long weekend coming up. Well.... we probably won't get to them until next week. I guess having a lot of power isn't really a priority with us. :)
If any of you have used or have knowledge of these batteries leave me a note!
