Flooded lead acid batteries must NOT be used in office UPC-backups. During last part of charging they vent oxygen and hydrogen in a perfect explosive ratio. That is why one has to periodically add water - to replace the water that was decomposed. They can only be used in a ventilated compartment.
Sealed lead acid batteries do not vent explosive gasses, and are OK for indoor use.

I did something wrong: I always lay the battery down, not upright always
Thanks for your info...

No worries, they are sealed anyway.
You might get slightly lower capacity if they lie down the wrong direction.

What does this terminal mean?
Terminals: F2
Per your advice, I will put it upright always from now on...

It's the flat connector on top of the battery.
F2 is 1/4" wide, while F1 is 3/16" wide.

Addendum:
Most UPS units have the F2 1/4" connectors and most off-the-shelf replacement batteries have 3/16" connectors - why? Go figure!
You can get adapters, but if you squeeze the UPS connectors a little bit with pliers they will be a sufficient fit on the new battery if it has F1 connectors.
2nd Addendum:
While I usually try to find Yuasa or Panasonic batteries which have (mostly) the best performance, you will probably get similar cost performance from cheaper off-brand batteries - you just have to change them more often.

Actually, AGM are perfectly fine on their side. There is no liquid rolling around in an AGM. That is only in flooded cell batteries.

This kind of thread is one of the reasons I love Code Project. There are so many finicky technical considerations for just about ANY kind of device and there always seems to be at least one or two experts who will respond to questions here. There are lots of other sites where you can get similar information but this one tops them all, IMHO.

Assuming you have one, take the battery here and let them deal with matching.

From my experience, you can replace the battery with any 1270, 1280, 1290 battery with the quarter inch F2 terminals.
For an APC UPS, you have to tell the ups that it has a new battery by resetting the date stored in the UPS -- otherwise it acts like the fresh battery is dead.

Our in-house language translation group was "de-featured" (laid off), so when we needed language translations for our new product's UI updated we went with an outside company. It's been a very long time since I've dealt with an outside company. I screwed up and didn't submit a purchase requisition in advance, and just had them go ahead and do the work. They finished satisfactorily, and submitted an invoice that was less than their original estimate. All well and good so far.
Oh boy  did I screw the pooch.
At last count there have been over 20 emails between me, my boss, Purchasing, Accounts Payable, and the contact at the translation company, all in the last 5 hours. I'm going to be really pissed if we screw up the relationship with these folks, because they did a great job, quickly, and didn't create any kind of fuss over the format of the text to be translated that I gave them.
There have been a number of times in the past when I've gone to our local computer gear store or Best Buy and bought stuff on my own dime in order to get the job done. I can't do that this time, since $16K is a bit much to put on my MasterCard.

what kind of languages does your UI need to translate?

The current product shows the UI in English, French, Italian, German, Spanish, Japanese, Chinese Simplified, and Korean. The previous generation also had Polish and Russian.

All of which probably comes close to the 16K of the invoice.

Close. We've certainly spent several hundred $ so far.

Sadly, this does not appear to be a joke. It is amazing how people like this survive for so long.
