There is no reason you should have to purchase them, that is the landlord’s responsibility. If management is not doing upkeep on aged-out detectors, that’s a call to the local fire marshal. Fire Marshals just love when high-life occupancies don’t keep up with fire code requirements.
I’d replace them, keep the old ones, and put them back when I move out. This is also my go-to with apartment showerheads.

Also a very valid route. Just depends on your tolerance and time for dealing with bullshit I suppose.
