Got this small UPS as a freebie, very very nice!
Anyway, I've been using it for perhaps two years now, the thing was made in -98 and has never had it's batteries exchanged yet it has worked remarkably well with very long runtimes... (Though I'm only taxing it max 20% of it's total capacity...)
When it was installed in the server room at the previous owners place it also worked really good, the only bad thing about it is that it is a single phase design, therefore it requires 30Ah on one phase which is not common in Sweden... We use 3 phase instead...
Anyway that does not matter because I am not close to coming near the limit of the 10Ah fuse... This was the reason I got it for free though... Because the previous owner got too many servers on it that the line to the UPS could not handle the load (the fuses eventually blew)
The design of the UPS is also really good, it runs the inverter constantly (double-online power conversion) which means that I always get a constant voltage out of it, no matter the input voltage... There is also no cut off delay before the batteries kick in if there is a brownout since the UPS is already running from the inverter...
See these two pics, they are of an APC Smart-UPS 1500, a pretty highend UPS yet it is not a double-online power conversion design like the Riello but a line-interactive design... The first picture shows it running from the power the Riello Power Dialog supplied, the second shows the power it is getting now that the Riello is not online anymore...

Now a week or so ago the Riello Power Dialog failed on me for the first time, the reason I found out when I opened it, one of the 22 7.2Ah 12v batteries had cracked open and was thus shorted... And the UPS runs them all in series giving 310VDC so the failure of one battery means the failure of the whole UPS... (most UPS are built this way...)
So now I'm on the lookut for new batteries, the original ones where made by a company in Italy (the UPS is also Italian) FIAMM-GS FG20722
These are very regular not at all fancy batteries with a design life of 3-5 years... Yet they held up for almost 9 years...
That APC UPS I was talking about, I've replaced the batteries in it too, it uses 2x 17Ah 12v batteries. The nice thing was that I managed to find batteries with a design life of 10 years instead of 5. Yet the cost was still 48% lower compared to APC original batteries... They are called 69-479-07 at Elfa.se
Elfa do however not have 7.2Ah 12v batteries with a 10 year design life, only 3-5... (See 69-532-30 which has the exact right size and terminals, or the slightly cheaper but with wrong terminal size: 69-532-28)
So I'm wondering if any of you that has not ignored my über long post by now have heard of any 7.2Ah 12v batteries with a 10 year design life that are not too expensive? The ones on Elfa with the correct terminal size costs 23.4USD when you buy more than 10...
Of course they would need to be located in Sweden or atleast Scandinavia because the weight of these batteries is ca 60KG! (least I wanna pay and arm and a leg for shipping...) They should also be new batteries, because the shelf life for lead acid batteries is not very good at all...
