I dont know how lead acid batteries degrade, but it doesnt just for example say less than 65% battery capacity it reports you to change them?
Couldnt you then just somehow put it to 45% for example and ofc make sure 45% is enough for your server/nas and therefore have it live for longer time?
I just remembered I still have had it plugged in to the cheap thing you put between it and the socket to measure power usage. Dont know how accurate it is but it says 37w idle now, and max it has been since I put it there (a few months maybe) is 66w. Tho I do not know if that is actually the most it can. PSU is 300w only because it was the smallest that also was considered good quality. Who knows if I will ever change the CPU with something more powerful or not tho, maybe I should pretend it draws 120-200w just in case?
Movies and stuff is only on there but important files there is a copy on my desktop, but if it outgrow the size of the HDD iin my Desktop then I dont know. That also do not have an UPS, because why would I.
Are SSDs more sensitive to power failures than what HDDs are? I dont have any SSDs in the NAS but I am considering getting some.
Also havent had anything wrong as I know with my Desktop through the years as I know of either.
Also, does it matter if an UPS is something called in line or offline standby?
As far as I know, I have never had a brownout here, only blackouts but as I said much fewer that some people seem to have.
