i've been quite happy with my eneloop rechargables for my M10.  i get about 5 hours with the batteries fully charged.  there are higher capacity options out there, but i have the most experience with the sanyo eneloop AA.  also, this is the charger that i use (LaCrosse BC-700) and it has been very reliable - http://www.amazon.com/Crosse-Technology-BC-700-Battery-Charger/dp/B000RSOV50/ref=sr_1_16?s=electronics&ie=UTF8&qid=1322767663&sr=1-16

I've been using Maha Imedion AAs for almost a year and have been really happy with them. I'm getting 16 more as my only christmas present.

I use this charger but  I think I bought a bundle with 8 batteries for around $55-60:

Another vote for eneloops, they're particularly good at holding a charge so you don't have to use them immediately.

Eneloops and Imedions are about the same, both are low self discharge and work well.   I use Imedions, and they also offer a 9.6V battery.

Heres what I use and LOVE IT :)
http://www.thomasdistributing.com/Maha-Powerex-MH-C9000-AA--AAA-Battery-Chargerbr_p_134.html

Good charger but somewhat confusing and over complicated in it's options.  I use that for inital break-in and pair-matching, and to revive old batteries for less critical non recording uses.

I mainly use another Powerex charger, which is as good for regular charging but super simple (only option is fast vs. slow charging) and runs off 12VDC so it works both at home and on the road in the car or from a 12V battery at festivals.  Here's a package deal for it with AC x-former supply, DC cigarette lighter cable, and 4 AA Imedions- http://www.thomasdistributing.com/MAHA-MH-C204GT-with-4-Maha-Imedion-AA-Batteries-and-Deluxe-Case_p_2570.html

5 hours doesn't seem like good run times for eneloop batteries in an M10!!  I usually get much longer runtimes using 2000mah and even longer with my 2700mah. 

i've been quite happy with my eneloop rechargables for my M10.  i get about 5 hours with the batteries fully charged.  there are higher capacity options out there, but i have the most experience with the sanyo eneloop AA.  also, this is the charger that i use (LaCrosse BC-700) and it has been very reliable - http://www.amazon.com/Crosse-Technology-BC-700-Battery-Charger/dp/B000RSOV50/ref=sr_1_16?s=electronics&ie=UTF8&qid=1322767663&sr=1-16

I exclusively use Energizer 2300mah AA's. They served me well over the year that I have had them, and once "Broken-In" on my Lacrosse charger, they last about 30hrs in my M10's :)

I use the charger cashandkerouac linked to at amazon although unfortunately it looks to be more expensive than what I paid. A taper named Frank (forget his alias here) recommended it over the $10 one I was using and I have no regrets of it.

I use Imedions batteries and got an 8 pack from newegg awhile ago for a pretty good price.
When I originally bought the sony m10 it came with non-rechargable batteries and that pair lasted MONTHS. To be fair, I don't think it was recording 2 hours at a time but it lasted awhile. However, using rechargeables in the m10 don't seem to last as long (even with correct settings) so I may try out a pair of one time use batteries to see if it lasts longer.
Advice is a form of nostalgia, dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it’s worth.

The two most important things to look for in any charger are independant charging circuits for each battery, and an internal charge control scheme that is more complex than just a simple timer.  Some cheap chargers have only one circuit and/or simply charge for a predetermined set time, regarless of the state of charge of the battery.

All chargers don't work for all battery types, so make sure that the charger is right for the type of batteries you are using (which means it charges at the correct voltage).

BTW, if you want a charger that works for almost every battery type that you'll ever use, get one of those Imax B6 programmable chargers on ebay for about $30.  It takes a little bit of knowledge on battery operation before you can use it confidently, but once you know how rechargeables work and how this charger works, you'll probably never need another charger.  I love mine...now that I know how to use it, I can fast or slow charge any battery at any rate that I want, although some batts (like SLAs) don't take a fast charge very well and you can go too fast and overheat any battery on fast charge...you just need to use some simple math skills and common sense though to use this thing properly.

Right.  The simplified points I make above about chargers assume use for typical NiMH batteries (namely AAA'a & AA'a) which the OP was specifically asking about.  AA & AAAs of both normal NiMH and Low Self Discharge NiMH type will be fine in any such charger.  The one NiMH exception I can think of that is tangentially relevant around here is a special charger is required to properly charge higher voltage 9.6V NiMH rechargables (either normal or LSD) that some of us use in Nboxes and Church preamps instead of disposable alkaline 9V batts.  But most users have seperate chargers for 9Vs verses AAs and AAAs anyway, and most manufacturers make seperate chargers for 9vs.

[edit- the complexity of using an advanced charger such as the Maha one Bean mentioned or the LaCrosse is mostly choosing between what mode you want (charge, dischage, cycle, break-in, and a few others that are combinations that I can never remember and have to get the manual out to remember what they do and what to use them for) and having to specify the charging rate you want based on the battery's capacity.  Those options make the charger more universal and applicable to older NiCads and other things beside NiMH AAs, but a simple good-quality charger that you simply stick the AA's into and a LED for each battery turns green when each is charged is the best and most economical answer to Noah's needs IMO.

In spite of my earlier message which may have implied differently, for the sake of the OP I second this statement.

You just need 2 or 3 of them so you can recharge quicker ;)
