Help with duracell

[cambel]

I my ex gave me some duracell rechargeables last christmas and I just got around to opening them up. Are these any good. they say aa/hr6/dx1500 nimh/1.2v/2000 mah. They do not say precharged on the battery so I am assuming they are not duraloops right? They came 4aa, 2aaa and a cheap wall charger. Watcha think? Also how do you know if a primary is good or bad. I ran down some cvs aaa batteries in my eagletac pn20a2 till the bulb went dim and I pulled them out of the light, checked them with my meter and they showed 1.33v I dont get it, shouldn't the light still work fine with 1.33v?
