How to extend the autonomy of smart ups 750?

Question

Uninterruptable power source

There is such a thing:
I have an APC Smart 750 (ups) It
takes exactly 4 minutes on new batteries:
amd fx-8350; bp corsair 850W; radeon RX 480; 16gb ram; 1tb sata + 128gb ssd samsung + monitor XG2700-4K (47 W) + router.
Is it possible to somehow extend the autonomy of the upsnik to 10 minutes? Are there any external batteries for it (something like a powerbank)? I did not find any information on the Internet.
It makes sense if I replace it with an APC Smart UPS 2200, will it last 10 minutes? or can I somehow overclock my 750?

Answer 1

Replaced with APC smart ups 2200.
Carries amd fx-8350; bp corsair 850W; radeon RX 480; 16gb ram; 1tb sata + 128gb ssd samsung in 4K resolution 15 tables poker stars + vk music + router + speakers with subwoofer 2.1 + monik 4k (XG2700-4K) + charged a couple of phones at a time. 6 hours in non-power-saving mode!

Answer 2

if you want cheap and cheerful, then take an external inverter and connect the appropriate battery to it.
however, it will be without a parachute.
