Received my batteries Yesterday and since it was so cold let them acclimate to room temperature before installing them into UPS unit.
Was an easy task with the exception of removing the old tape which kept them held together so wound up using some medical tape to hold them together.
All put together and plugged in and powered up all is well and after a few hours of in use charging will remove house power and make sure they hold.
Amazingly when I tested the old batteries they read 12 volts and 11 volts although that test was without any load on them and the fact there are signs of minor swelling I almost certain under load they would fail.
I guess the powers in charge have a way to mark this tread [SOLVED] as I see no way of doing that at my end.
