I have the Synology DS920+ (having purchased it last year based on recommendations in NASCompares 
that replaced my older DS214. I purchased the APC UPS (Back-UPS Pro BN1500M2) in 2018 for the DS214 and continued to use it after setting up the DS920+.
I have since learned that the BN1500M2 is not on the Synology Products Compatibility List. I uncovered this when I thought my UPS was not operating properly as part of the graceful shutdown in the event of a power outage.
After much consultation with APC and Synology support, both suggested I replace my UPS with a model on the Compatibility List and I selected the APC Back-UPS Pro BR1500MS2 (sized and recommended based on my load requirements). I have also learned through this process that as part of the graceful shutdown, the NAS never powers off. Instead, when the NAS loses power, the DSM shuts down (as I understand) all the critical apps and resources on the NAS and allows background apps, i.e., the ones when the NAS was fresh out of the box, to remain on until the UPS battery runs out of power.
So with that as my understanding of the interplay between the NAS and UPS, I am wondering if I can use my existing, but not necessarily compatible BN1500M2, or should I keep the new BR1500MS2. The specs are close between the two models.
Thanks.
