don't think he will be responding anytime soon

Uh oh, that's not good...

Anyway, I strongly recommend the Sony batteries as the quality is guaranteed.  With all lights turned off and phantom 48V turned on (to a pair of schoeps ccm4), I got 14 hours with the npf970 (6600mAh) and 8.5 hours with the npf770 (4400mAh).  You can't beat that kind of battery life.  I would estimate even the small npf570 (2200mAh) which barely sticks out (I think) should last over 4 hours with phantom on based on the other two.  They cost more but definitely worth it IMO.

Check out the Lenmar battery above as they have better than average quality control on their batteries.  The LIS970P is the big daddy at 7800mAh.  $51 and free shipping to boot.  Such a damn good deal i'm buying one myself right now.

thanks Dave. for that price, i couldn't pass one up. actually had bought 2 7200mAh generic ones off of Ebay and it didn't last. Not to mention one of the pins came out after the 2nd use. WTF. what a piece of crapola.

Thanks. Grabbed one. There are 2 left.

So how do you tell if they are going to fail early? They just don't hold a charge as long, or do they die without notice?

You've spooked me now. I've received one that was posted either here or over on the SD forums for $35 shipped (a 7600mah I think), and now I'm curious just how much I should monitor it or whatever. I'm coming off of nimh batteries which I didn't have issues with (that weren't due to other environmental reasons) and I'm mildly worried now.

if you stick with the lenmar brand you shouldn't have to worry one bit about power.

I bought a few generic batteries off of Ebay a while back, some will power my 722 for 6+ hours yet and some go dead in under an hour. Every six months or so I run a test on them and mark the run-time on the side of the battery. Once they get too weak to run a complete show, they go for recycling and get replaced with a lenmar 7800.

I have never had one just fail, it seems as though they only loose capacity over time.

Ah, excellent. I understand anything can happen, but the information is comforting.

Glad I could help.   For $50 it's a steal.   Lenmar also has a 3 year warranty which the knock off batteries don't.

After I picked mine up last night there were 19 of them left and now there one.   Good job ts.com

Lenmar batts can now be found on Ebay w/ 3 year warranty

I scooped one of these a couple weeks ago.  Haven't taken it out of the package yet though.

Can I just confirm this is the battery most recommend?  It doesn't say it on the auction for some reason, but I believe it is 7800mAh correct?

Thanks.

Just wanted to update as I got my new battery today.  Ordering and then the free shipping took a total of 7 days. 

Pretty damn good for the price i'd say.

I just picked up a couple of these - thanks for the recommendation!!
