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 batteries to use it?
Because I have a 20000mah inui battery that is rated for 12v at 1.5A is this a good practice to buy several of these (since they are about 20 bucks) disassemble them and use them as ups batteries?
A larger battery generally works fine with an older, dumb UPS. You will just have to connect an external charger if the battery gets deeply discharged. Adding a cooling fan to the UPS would be a good idea since it will be running for a longer time though.
I’ll admit, it could, but the battery conditioning might still struggle.
