Salvaged SmartUps 700XL

[Anonymous user]

Hi,

I got a salvaged 700XL Smart UPS.  UPC: SU700XLNET, S/N: QS0132213016.  I'm guessing the batteries were dead, but I don't know the voltage or anything.  Are the batteries in this unit 6Vdc or 12Vdc?  I've not seen any 24Vdc, so I'm guessing that isn't a concern.  Most likely I'm guessing is that each is 12Vdc for a total of 24Vdc.  They are connected in series.  Are there schematics available?  Most producers of these old units publish their old manuals.

I'm retired and can't afford to buy a new one.  I'd really like to get this working.  A thunderstorm took out my computer powersupply about a year and a half ago.  I had this ups, but non-functional.  My wife passed away and I'm trying to get caught up on old projects I had to put aside to take care of her.

Any and all help will be very much appreciated.

Shalom,

Iyyov

Hi Iyyov,

This unit uses a 24 volt battery module, part number RBC7. The unit will not turn on with a bad battery, so it is possible that it just needs to be replaced. I would like to note however that this unit is approximately 18 years old. Typical lifespan of a UPS is more like 10 years, so you might want to take that into consideration when deciding to purchase a replacement battery. We do not release schematics or support component level repairs on this type of unit. They are not considered to be field serviceable aside from battery replacements.

Thanks!
