Curious. And if they have been verified to be the same, why not?
can I mix Eneloops and Duraloops in one pack?

They won't have the same manufacturing date and come from the same batch off the production line, so they will not be the same. But sure, you can mix anything with anything if you want. Do you feel lucky, that's the question?

assuming your stash of eneloops are all around 2000mah and not have one thats 1600mah or below I don't think you'll run any significant risk. then again...the magnitude of the risk is entirely dependent on current draw and frequency of use.

you could always try carefully without ruining things, by testing. your talking SERIES right?
discharge and recharge all of them one time, then assemble the series set, then load it down, and go down the chain of series items with a voltmeter and read each cell, then discharge the whole set till one battery is exhausted 1.0v , and then discharge the remaining in a discharger singularly and check the capacity left in the remaining.
or variations of similar things just so you know about where your standing with the set. after all the reverse charge IMO is the best way to rain on this party.
even from the same batch same brand and same year and age, there will be some variations, using this testing method, the more the variation is, the worse it will be for you and the batteries.
without working them as a series TEAM, a resistance difference will not show up, so if you just use some ma Numbers , you will also have to get resistance numbers (somehow) before the numbers are usefull.
or just get more of one type.

The only risk in this situation is to the batteries. Whichever battery starts off weakest runs the risk of getting even weaker over time. So for the best run times and the longest lasting battery pack, you should choose the best matched cells possible before assembly. If you pick cells from different sources you are starting out with a handicap, but whether that matters is up to you. It won't be a disaster, but it might not be the best possible.
Thanks for the input, and no I don't feel that lucky. Bottom line it sounds like I could end up ruining expensive cells, although I do check mine frequently. I have not yet been able to afford a charger that will also discharge cells... I think I'll stick with a single manufacturer and avoid extra headaches!

Providing you have the re-badged Eneloop and not the Duracell Pre-charged that's made in China, the major deterrent is not in mixing Duracells and Eneloops, but in mixing cells that are in significantly different condition.
If the time comes when can afford a charger/analyzer, you can reduce this deterrent and enhance the performance and longevity of your cells in multi-cell applications by following this performance matching regimen authored by SilverFox in another thread:

there is usually a reasonable assumption when a question like this is asked, that the batteries were purchaced in different lots , times , or have different use, even if they are the same cell item.
that the batteries cannot be from the same batch or time, or anything.
When making a SERIES pack it is always great to start with a set of cells that are very similar in all areas, and have a few extras, then do the series testing, and toss the ones out that you think dont match well with the others.
then, it is a much longer time before the series set goes to heck on you.
