Battery backup
I have the model X88 internet gateway. It's the only device plugged into a 950VA battery backup. During a recent power outage, the backup battery was drained after, maybe, two hours with no internet being used. We also use Xfinity for landline service, so no gateway equals no phone service. Before I invest testing and charging/replacing the current UPS battery, I'd like to calculate how many VA is required to power the gateway each hour of battery drain. Does anyone have a formula for that calculation?
Thanks

Thank you for reaching out to our team here about that battery backup issue. I know how concerning any power interruption can be. I do not have an exact formula showing for that type of backup. I did find that a 950VA (approx. 480W–510W) battery backup unit will power a standard internet modem and router for roughly 2 to 4 hours during a power outage. Because a small modem/router combo only draws about 10 to 20 watts of power. We do offer a lithium-ion battery unit that provides continued Xfinity Voice service during power outages. The backup battery will ensure phone service remains available for up to 24 hours in the event of an outage.
