After clarification with our responsible department we recommend you the article that you find on the following place:

You won't find any information about network, IP, etc. for this UPS because it can't be managed via network.
You are left with USB or serial.
Yes, it works with one of my devices (Thecus N7700), but not with the other (QNAP 219).
The communication options between the NAS and the emergency power supply are very limited and are not covered very well in the manual.
Conclusion:
I am very satisfied with the emergency power supply.
However, I am very dissatisfied with the instructions and the connection/communication options.
I don't quite understand your question, could you please be more specific?

The correct replacement battery for the APC Back-UPS Pro with 900 VA and 540 W (model BR900MI) is the battery labelled APCRBC164. This is a VRLA (lead-gel) battery with a capacity of 128 Wh and a typical service life of 3 to 5 years. It is used specifically for this UPS model.
Automatically generated from the .
Unfortunately, there are two APC900 models - old and new. The new models need no. 164, the old ones need no. 123. Unfortunately, I ordered no. 123 first and then had to send the battery back. Tip: simply remove the old battery and compare the photo. If it is split in two, it will be no. 123. If it is a single large block, it is no. 164 (just look at the photos at Galaxus).
Thank you very much for your feedback! If required, you are welcome to leave this via our star function so that it is more visible to our customers.
On the Schneider Electric website they write 6 watts. I can't measure this because I would have to shut down and reconnect everything.

Hello Yoichi, Yes, the cable was included in my delivery.

This will probably not be enough. Because if your PC is running at full load, it will "say" more than 540W. It would be helpful to know which power supply you have, the UPS should have the same maximum output as your power supply (otherwise the power supply can only draw as much power as the UPS delivers). The graphics card and CPU alone draw more than 540W under full load (according to digitec, up to approx. 700W and this does not include fans and other components). It also plays a role what your goal of the UPS is, should the operation be ensured in the event of a short power failure, or should the UPS also last longer? Then it is no longer the maximum output power but the capacity of the battery that is decisive.

The output of this device is low. From the manual, maximum output:
540W or 900VA

Thank you very much for letting us know. We will be happy to pass this on internally to the responsible department and hope that this will be checked promptly. Actually, something like this should not happen.
Helpful answer
Yes, it will work just fine. The limiting factor will be the 390W total output capability of the UPS. The multi socket of your choice will handle 10A which corresponds to 2'300W.
Greetings
That is not included with this UPS. I used one from an old PC.

Hello, I have not measured it, but the UPS has an efficiency of 97.4% in no-load operation. At 540 watts, this makes a loss of approx. 14.04 watts. However, since the UPS should be max. 70% loaded, this makes approx. 9.8 watts.

Unfortunately, the product manager was unable to provide any information on this matter, so we can only ask you to contact the manufacturer directly. We are sorry about this: https://www.apc.com/hr...

This inverter does not appear to be listed as compatible with the DS920+ according to the manufacturer's official list: https://www.synology.com/fr-fr...
Question 1: I have no idea. I have my NAS connected to the mains cable to shut it down automatically (happens automatically between the devices).
To question 2: Yes, they are indeed very easy to replace. They are not connected when delivered and have to be connected first. Provided you can get a plug into a socket, the connection should be successful.

Hi, I have a DS-Slim that works exactly the same, just perfect. The way I got to know Synology, it will also work with your NAS.
In my knowledge, the UPS has a USB interface for Power Management by one device, like a server or NAS. I am joy sure you can use the SNMP protocol over USB
Hi Marvin, there is a fan inside, but it is quieter than my NAS. However, switching to battery is clearly audible (several times a day for me). The behaviour of the display cannot be influenced, not even by APC software ... but it switches off automatically. Unfortunately, the shutdown only works via USB. The network connections cannot be used in this way. I have connected the UPS to the NAS via USB and shut down my WIN server from WinNUT. MfG digimouse

Hoi - you can prioritise subjectively (my 8k screen is more important to me than my PC) or by price of purchase (my xykCHF PC is more important to me than my 2.7k screen for xxx CHF) - or by: how fast or difficult will it be to find a replacement for device Z if the worst comes to the worst (e.g. if the insurance, if you have one for something like that, hasn't paid out yet) ...
I have e.g. my 3 NAS and the firewall (yes, it's a more abnormal one with many cores and lots of RAM and many interfaces) on the UPS ports, 2 TFT, 2 docking stations, 2 pairs of active speakers on the Surge ports... According to the motto: I can't work without data, restore took a relatively long time, notebook and data are important to me... Find the points that are important to you, then you can rank them.
Hope this helps and Lg
