the APC runtime charts are fairly accurate for new fairly fresh, full charged batteries (batteries do age and lose capacity overtime and depending on the number of extended discharges), for something a vital as phone serivce/VoIP (you're not just looking to shutdown gracefully, but maintain service for an extended time/as long as power is out) you may need hours or days of capacity , beyond a few hours automatic generator and load transfer switches are more practical/affordable then massive battery banks
remember to add the modem/ routers and phones to the protected load side and calculate your needs accordingly.
How large a system do you plan to run? |
