Rechargeable 9 volts in an Nbox (revisited)

tired of buying 9 volts? I am giving rechargeable ONE more shot.
I highly recommend Thomas Distributing.

MAHA POWEREX 9.6 VOLT 230MAH NIMH

MAHA MH-C490F 9 VOLT BATTERY CHARGER 110V AC AND 12V DC POWER

After charging and discharging five times, here are the times i got with these

3 hours 50 minutes then reversed the 4 batteries with no charging
3 hours 35 minutes then all 4 batt are dead
-------------------------------------------------------------------
7 hours 25 minutes on one set of 4
I repeated this 4 more times and got almost the same exact run times


When inspecting the waveforms, the sound is perfect until the very end, there are a few spikes
sometimes loud static for a few seconds, then nothing.

I'm pretty sure if i discharge and recharge the batteries properly this time, i won't have any failures/user errors.

Thanks for the info Ed...The wife bought me 8 of these and a 10 battery charger for my birthday and I must say I am impressed with these bad boys..At full charge they have anywhere from 11.30 to 11.54 volts and seems to hold up well in the Nbox...Ran a 3 hours show the other night and tested them when I got home and they still had 10 volts on them..I give them a  :coolguy:

interesting. a little hot for the CMRs unfortuantely. (they spec it at 10V max which just covers a full 9V alkaline)

So, roughly how many nbox's are there out there?

2 reviews (including Nick) makes me "warm and fuzzy" but still a little bit scared, only because I remember someone in the past mentioning that they lost songs at a show because the rechargeables died early

I attached the soundforge look of a show were my 9v batteries died early, more for reference than anything else... and I tried using 9v that were partially used (save money and environment), here are the battery pre and post show (I was not tracking which slots they were in at the time):
8.24 > 7.49
8.24 > 7.50
8.01 > 7.84
8.00 > 7.60

I have been tracking (as best as possible) every show and the pre/post reports; deck used; approx time run; where in the venue.... interesting results, I can post the spreadsheet if anyone is interested.

so whats a realistic battery life (assuming swap) with fresh alkalines in an nbox+?

I have 31 performances/shows (some times I have changed batteries at set breaks, etc) and I cant find a pattern or a common denominator with my own data

Am I missing something or are you saying that you would rather use used batteries than give these new 9 volt rechargables a go ???

These batteries listed are much better than 9 volt rechargeables from earlier years..Make sure you buy the proper charger for them...It's critical!

I don't think it would damage them in any way.

I am strictly trying to get some technical details and/or better information before I go out and buy batteries that a week ago everyone swore against (in the nBox thread)

Well so far I see no issues with using these rechargeables...I have also numbered the 8 I have and am keeping track of how they are used to determine how long they last before no longer holding a good charge.

Note that we're talking about two entirely different beast here.
The (legacy) rechargeables marketed as 9V only had a nominal voltage of 8.4V.
Edtyre is reporting his results using true 9.6V rechargebles, which contain one extra internal NiMH cell compared to the legacy ones.

The OP might consider changing the subject for clarity...

Yes, i changed the thread to read "9.6 volt rechargeables"

These newer ones are what i tested. I saw what Nick posted and decided to
give rechargeables another shot. All of us are tired of using batteries and throwing
out ones with half a charge. For my stealthy applications the run times are fine.
