Powerex have been a Broadway standard for years. B&H is a good source.
For those that don't know... Maha Energy makes PowerEx.

We are using IKEA Ladda for about 1 year and so far so good. Buy the one made in Japan (usually 2450mha).
If you want to explore further, this site is pretty good

One additional advantage of the Eneloops is very low self discharge. For those doing shows weekly this may not be a problem; for those of us who work more sporadically, my system of a “Charged bag” and a “Dead bag” works even with gigs months apart. For standard NiMH batteries I would be less comfortable using a battery I last charged 6 months ago.

+1 on the Eneloop Standard (white). For high drain things like digital camera flashes the pros allow the flash to recharge faster; for typical production wireless usage, the extra current capacity of the “pros” isn’t worth it to me.

This is definitely an important consideration (IIRC most NiMH batteries will be pretty flat after 6 months). FWIW, Maha's "Powerex Precharged" do fairly well in this regard as well.

This is excellent advice. Thank you. These will be used in a high school and will likely sit unused for extended periods of time.

Regardless of advertised self-discharge rate, for NiMH batteries that have been sitting for a while I would always recommend charging them again before their next use.

Yes.... I always charge again if I have gone out more than 3-4 weeks. In fact if I want to quickly check my batteries in the EW packs, I can guarantee that some of my other batteries will show only 2 bars after a couple of weeks but the Eneloops will show 3 bars.  I realize the calibration in the pack is unreliable with rechargeables compared to Alkaline but it can still be used as a basic guide in this way.
