Air cylinder help

[IAfaug]

Ok so I acquired a couple small cylinders in a large purchase and i dont understand what value these could be for me can someone help?

one is a GURLLEU .5l the other is a acecare .35l

first question is how full can i fill them with my compressor? The gauges go to 40 MPa

second how many top offs are they good for?

I have a Benjamin akela and p rod in 22 cal

or since this setup also had 2 18 omega 18 cu ft tank should i just sell these(the 2 little ones)? 

Thanks

You are not going to get much out of the small bottles but the 18 cu ft tanks are useful.

Are the small ones alu or CF?

If alu then most often 200bar~3000psi and if CF then probably 250-300bar~3625-4500psi.

They (alu) are good for nothing regarding PCP, maybe half a rifle fill at best.
