Why is my fire extinguisher emptied after one use?

I'm planing to make small diy gas chamber and I saw people using old or used fire extinguishers but I don't understand why my fire extinguisher can't hold pressure after one use ?

I have this fire extinguisher about 3 years and it was holding pressure but few weeks ago my home workshop catched fire from lithium ion battery explosion and I used my fire extinguisher to control fire but I only used a little bit and after I used pressure gauge showed the half of pressure remained but after few weeks pressure slowly leaked into zero

All fire extinguishers do that or mine just a cheap one ?

Fire extinguishers with plastic heads cannot (or should not) be refilled (recharged)...only metal heads.

Plastic heads can split, crack, etc. over time. Either they won’t take a charge or they’ll loose a charge over time.
