The 1350VA rating is what the INVERTER can deliver. The runtime is determined by the capacity of the BATTERIES, the load, and a few other variables. On a related note, I absolutely despise how companies advertise UPS's. They always advertise the VA rating. In the era of PFC power supplies, the VA rating is even more useless. Even in the past, it seemed most UPS manufacturers pulled VA rating out of the air. I suggest looking at the max wattage rating instead. I always recommend getting something rated MUCH higher than your equipment needs.
My other big issue is that the manufacturers don't tell you the battery capacity. That is what has the biggest impact on runtime, aside from load. For decades, they have been pairing larger inverters with smaller batteries. I remember encountering an ancient 200VA UPS with a 7Ah battery and years later a 350VA model (from the same company) with a 3Ah battery. In my opinion, they use batteries that are too small for the inverters they are paired with. If the inverter is loaded anywhere near capacity, it seems to greatly decrease the lifespan of the battery. This is why I suggest buying greatly oversized models these days.
Here is battery specs, for those interested.
2x replaceable CSB HR1234W 12V 9Ah batteries
When the batteries die in these UPS' I've had good luck replacing these 9ah ups batteries with Power-Sonic PS-1290 battery, cheaper than buying through APC and they have more lead in them. (they weigh heavier)
I have a 1500va and it can run my network gear for 2+ hours (8 PoE switch, 16 port switch, 2 acces points, 2 routers) mostly Unifi equipment
Hope this helps but it's very dependent on the load

Is there a way to know the capacity of these?

I have always liked APC for their UPS's, always been good quality, I might just go ahead and grab this deal, it's almost too good to pass up considering the UPS alone is selling for $175 at Amazon
I bought one, I have a BR1500MS and it works well, I could use another one (though slightly smaller) and this other thing is just a bonus, not sure what I'd use it for.

Here is battery specs, for those interested. [two 9ah batteries]

When the batteries die in these UPS' I've had good luck replacing these 9ah ups batteries with Power-Sonic PS-1290 battery, cheaper than buying through APC and they have more lead in them. (they weigh heavier)
anyone comforted in knowing these are replaceable... go look up the price now... cause you frugal guys wont be replacing them at the price they're sold at.
Its a universal battery, here is the one I buy to replace them with. Can be had for cheaper, but I like the brand.
