Question about rechargeable batteries

Question

I just found some rechargeable batteries that I haven't used in like 2 years, my question is... Do they still work? I put them in the charger, but I don't know if they still work since I haven't used them in a long time.

Answer 1

they shouldn't as long at they don't have any corrosion on them. But you should be set. If they don't work it should be pretty obvious.  

Answer 2

If you try it,it might be blow up or not.
