Yes, I have seen that name, online, on some units.


The DeepL translation is not good. The vendor said "on wait (out of 
line) or Standby (Offline)", the second part in English. Probably a 
translation itself. I'm thinking the "or" is because they used "Spanish 
term or English term"

Right.

At a telephone exchange I found one "online" UPS cascaded from an 
"offline" UPS, IIRC. Used on the control room hardware (displays and 
printers).

Yes, I have seen this. The house goes slightly "brown" and the UPS 
becomes active, I hear the clack of the relais and the buzz of the 
transformer.

Right, they call this "cold start".

This is more difficult to find from the specs. Price could be an indication.

Hah! The warranty is two years :-D

However, I do have another unit from this brand, and the battery did 
last longer. This particular unit uses two batteries, 24 volts, actually.

Usually, I stick a label outside where I write the date when I replace 
the battery, and the price, but on this particular UPS I don't see the 
label. So I don't know the actual duration. Maybe I put the label inside?

That's funny. My car battery is currently 6 year old, and going fine, 
according to the garage (they just checked it). There was some 
"sulphate" on the lead stud which I told them to check.

And here it is hot weather, for about 5 months a year. :-?
