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

    I’m not that good in electricity but basically are lithium batteries from power banks would work the same as 12v lead car batteries?

        On the paper they are 12v, so what makes the real output voltage

            It is written on the back of the powerbank (sorry but I’m not so good in electrics)

              If you’re this confused you shouldn’t be trying to change battery types in a device that can power appliances.

                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.
