Acrylic Tank Lifespan

[salmon alley]

Do acrylic tanks have a usable lifespan? I've got a 54g corner tank which has been sitting in storage for 18 months. I purchased it used about 3 years ago, but had no idea how old the tank was when I got it.
Assuming it has no leaks, is it okay to use? Is there any way to determine if prone to failure?

Thanks all!

It should be fine. Like with all tanks just check for leakage. I'm sure these tanks set for years at the warehouses

just don't stress it by trying to move it while it is half full.
