Both of those batteries look like they'd do the trick. 

I guess you could say the 3600mah battery is about the same as using 3600mah AA batteries wired in parallel.  Easier though if you know the current consumption of the MR-1.  I have no idea, but with a modern design and good attention to power management, I'd take a total guess that the MR-1 consumes 300 to 500mA of current.  So a 3600mA-hr battery divided by 500mA of current draw, means 7.2 hours of record time available from the 3600mA-hr battery.

Thanks! I think the safest will be using the 5400 mAh one. You can get this in ebay which is tempting:

MR-1 has a consumption of 2.15W and takes in 5V...So 2.15W/5V=0.43A = 430mA

Battery is 5400 mA/hr

5400/430 = 12.55hrs running time (seems good!)

This one's not stealthable, but just got off the phone with the rep at the company and it has a whopping 11,000 mAh at 5v!

This one's more stealthable, and still has 3400 mAh:

I'm doing the exact same with my MR-1...
AKG 461's / 463's OR Senn MKH 8040's > MR1000 (Busman mod) or Shure FP24 (aka MixPre) > MR1 (open)
Coresounds Binaurals > CChurch 9100 > MR1 OR AKG CK1x/2x/3x > Deneke P20 > MR1 (low profile)

I'm a bit confused from the page - can it provide power to say, the mini-usb on my Microtrack 2496, or must you use one of the regular round dc connectors it comes with?

Similar question: someone gave me a LilSync 4 AA pack that takes either alkalines or NiCad (according to the Web site). The retractable cable he had with it is usb on one end, but some sort of specialized connector on the other end (wider/flatter than USB, and locks into place).  Can I get a LilSync cable to use this pack with my Microtrack?

Interestingly, I tried hooking up the LilSync pack to my Microtrack using a conventional USB cable plus an a Radio Shack adaptr to get to the right mini-usb size, and nothing! No juice from battery pack to Microtrack.  Does this pack really only work with LilSync brand cables? Bizarre!

Sorry for the really beginner type questions - I'm not at all a IDIY type.

thanks
Chris

To PP-99 LiOn pack users, need some help.

I just got a PP-99 LiOn pack.  I have charged it all weekend and I thought the red lights were supposed to come on when fully charged, but no llights come on.  Do the lights come one when using it to power something?

Lights come on when you plug in the output cable.
