I have an UPS with two 12v 7ah lead batteries. If I want to change the batteries I would typically go with lead batteries but here’s my question, can I use some portable mobile power banks to use it?

Because I have a 20000mah “INUI” lithium power bank that is rated for 12v at 1.5A, is it a good practice to buy several of these (since they are about 20 bucks) disassemble them and use them as ups batteries?

EDIT : clarifications

      Ohhh okay, sad… Is there a way to get these 12v to use it instead of the stock lead batteries?

        Not easily or cheaply, because of the voltage mismatch. Using a buck / boost converter setup tuned specifically for the UPS might work but would be pricey and probably not that reliable.
