Just checkin in to say i'm sold on these, like Craig T have been using these for over six months with no issues at all. This is the solution we Nbox users needed :-)

ditto. i have eight that i've been rotating and only had one issue the first time i ran them at a festival. i was definitely pushing them and over estimated runtimes. when in doubt, flip em anyway.

Fuckin' awesome.

I needed a low price gift for a X-mass swap. This will work nicely.

Ill vote YES these work fine as well.
The one thing I have noticed, is that they dont always charge back up to the same levels and that they loose about 0.10v per day just sitting around (so dont assume they will be usable in a pinch for time)... they also dont wear down at the same rate from show to show (not sure if that is related to the difference in shows (location, SPL, etc)), but I will still continue to use mine until the recharged voltage is lower than 9 and I am currently seeing 11.15 on average off the charger (with most readings once the batteries have cooled to room temp)

How about these?

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330378729926&ssPageName=STRK:MEWAX:IT

I think Li-Ion batteries are better than NiMH because it holds and charge longer and can use in cold outdoor conditions. Also lighter and easier to carry. Anyone thought about using Li-Ion rather than NiMH?

No - they're not "true" 9v.

"Nominal Voltage 7.7V pack with a peak voltage of 8.4V "

How about these?

hi!

I just got these, and I'll be using them in the nbox soon... iIt says on the battery packaging  that there is no memory in  them, which I suppose should mean you do not need to fully discharge them after every use. Can someone advise as to whether this truly is right? If not, any advice on how to discharge them?

I was just thinking the same thing. I have done 30 shows with these so far, and i have been
dropping them in the charger right after each show. One pair charges right up and the main pair
takes a while. I have mine numbered so i switch the pairs every show, so far this is working
perfect. What do you think?

Have you checked whether they give you the same amount of time in the nbox after a while?
I seem to remember reading that this memory thing is a thing of the past, that was mostly a problem with nicd batteries, but I've never checked it properly. The AAs I use in the R09hr I've always discharged before recharging, but it's probably not necessary...

So what is the general consensus on these? Still the way to go? What charger are people using? The 4 channel MAHA or the 10 channel that Nick got?

I have been using the 8 batts in rotation on and off of my MH-C1090F 10 batt charger and have been pleased by the results..I also like the idea of having the spare batts on hand at shows, so instead of swapping pairs I just change out the one pair with freshy's.

I got the 4 channel Maha, and it seems to work fine. I 've just done two shows yet, but the nbox seems to work fine for approx 4 hours (without switching the batts)...

After staring at a pile of 52 9V batteries on my desk, I finally broke down and bought one of these. I find it absolutely hilarious that the 4 channel MH-C490F model is called STEALTH! Too bad about all the red lights.  ;)

Awesome post. I was just thinking about this today. I've got an N-box on order right now and was just looking at these exact rechargeables on newegg.com. It looks like I could get close to four hours on four of these running the nbox, which should be enough for the shows I go to(stealth--don't want to have to worry about another four batteries to swap out). I'll just have to make sure to turn the nbox off after each band when there is more than one band playing that I want to tape.

Would new batteries give an even longer running time for the n-box?

Not sure what you mean by new batteries. A new set of Duracell Procell 9Vs lasts 3.5 hrs on the change every show side.

These 9.6Vs when freshly charged start at around 11.3V and last 4 hrs on the change every show side. After that they are around 10V, but I tried running them longer and after an hour they read 3V, so I would swap them after 3.5-4 hrs just like alkaline 9V.
