I'd strongly suggest having a look at
comments from a previous offering of these batteries. There were several unhappy customers, including me (but a few positive postings, so read them and see for yourself).
Basically, these batteries have documented poor performance at high loads and anecdotal reports of other problems. Of course I don't know if these batteries are from a better lot, but I checked the date on the sub-par batch I got and they were fresh. So unless the distributor posts that they found and fixed a quality problem there is no reason to believe these are any different.
Assuming this is the same source vendor, in that older discussion you'll see them promising to ship replacements -- but I never got mine. However, the Woot staff did make it right for me after I let them know (thanks!)
In the end, I went down to my wholesale store and got a big stack of Duracells for a little more money and I am **so** much happier now.
