Lg Stylo 2 ( Model K557) or LG V10 (Carlingwood)

Looking for a LG Stylo 2 (model K557) or LG V10 phone.These cell phones are almost obsolete but I could use one of them and extend its useable lifespan. I just got a battery for my Stylo 2 and the phone broke so I would like to be able to use the battery. Thanks for your help.
