But that's usually not sealed is it?

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.

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

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

Flooded, are, by definition, NOT sealed. There are maintenance ports on them to allow checking the condition of the "water" and to allow you to top it up. You cannot operate a flooded lead acid battery in any position than its access port facing upwards.

Sealed Lead Acid Batteries comes in two variants.
You're forgetting the third and most common form of lead acid battery, the flooded lead acid battery.

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 have a UPS backup device to protect my workstation DELL T1700 in my home office. the battery needs to be replaced. its brand is: DURA12-7F2 AGM. its technical spec is: 12V 7Ah. for this kind of battery, there are lot of options in Walmart store. But, I noticed there is "AGM" on current battery. not sure what it is and here are my research: 1)Maintenance free AGM technology. 2)AGM stands for Advanced Glass Mat Technology. So this battery is a little different than universal battery USB 1270 battery, but not sure the exact difference. Curious to check our community here to solicit some insights on this battery.

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.
