9/6: Jim replaced the RBC55 UPS batteries. There were four replacement batteries. He took out the old battery cartridges but had to keep the connections and covers for them to use on the new batteries. The new batteries just had to be screwed together and wired the same way the old ones were. Jim put packing tape around them to hold them together. There was a piece of foam that may have been between the old cartridges. Now it is between the new batteries.
