Energizer rechargeables and slow recycle time

I just bought a set of the Energizer rechargable batteries and the 18 minute charger, tonight I was shooting a wedding rehearsal and noticed that first time using these, they have a hellish slow recycle time. I charged them up about 4 days ago and havent used them.

I had to switch back to regular non rechargeable ones... I have heard good things about these but I havent had any luck..

any thoughts on these?

this is similar to the pack I got... http://www.amazon.com …2L7E/ref=pd_sim​_hpc_njs_2

Eneloops work well for me!
