asked on Battery UPS APC SC1500
I have an APC battery backup, rack mounted. This model, SC1500, has a series of 4 batteries and the batteries were screaming to be replaced. I had my boss order the batteries and we got them but they were 4 unlinked batteries. This is a pain. I attempted to connect them the same way they were connected and got a spark. After that I got a bit nervous and I can not find a diagram for these batteries and how to connect them.
Does anyone have any idea?

If the batteries are the same, I see no issue. But the instructions to replace the batteries will have some note about switch the UPS off before replacing. Can you check that? A small spark would be expected because the new batteries will be empty and will get charged once connection is made. How big a spark is it? Check polarity and measure voltage on new batteries if possible.
I recently had to replace the batteries on a much larger APC and, after inspecting the battery packs, opted for buying the assembled batteries rather than trying to pry the old ones apart to move the wires!
If you are scared (which I can understand!), unplug all of the computers and use a trouble light for testing.

I figured it out. First my boss wired it and I was relieved but it was tested at 24v and the back of the unit states 12v so I gave it a go and it measured 12v.... I installed them and nothing blew up ;) but the building wiring fault is on and a constant alarm.....

Also the spark was initial spark was between just the batteries not the unit :)
You need to download the users manual so you'll know how to check the status and what the errors mean.

I thought it was 12v but I think I just caught a glimpse of the 120v marking and translated it in my brain to 12v. I think we will be switching it to the 24v (which is Davids suggested connection I believe) configuration and trying again. Thank you guys for your help.
