I'd recommend you spend the bucks for a 3A-40BC extinguisher with a
pressure gauge  and a metal safety pin (or more specifically, *not*
the Kidde models with the thin plastic safety pin which can be
accidentally pulled much too easily - and pulling it breaks the
latching tip.  I've determined this by long experience in boats and
vehicles).  Check the pressure routinely and turn it upside down a
few times once a year and it should be good for many years.  Costco
and similar often have these for good price, maybe $20.  Of my three,
the two I can lay ready hands on were made by First
Alert.  Occasionally (two out of the maybe fifteen extinguishers I've
bought over the years)  one will lose pressure -- unless you've paid
extra for the refillable kind that ruins it, but you might consider
using it for practice.  It's been shown that people are fifty per
cent more effective the *second* time they use a dry extinguisher,
because they know what to expect.

Anything plastic becomes temporarily brittle at some temperature, but
that aside, shouldn't be a problem.
