Rechargeable 9.6 volts in an Nbox (revisited)

[jerryfreak]

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

probably not but bernhard said dont go over 10V and i dont wanna be a guinea pig!

[T.J.]

What's the deal with these? Still positive experiences? Got a festival labor day and thinking about taking the plunge. How is Thomas with shipping rates/time?

I've been happy with these rechargable 9v NiMH batteries:

They charge to a little over 10v, but after a day they settle down to 9.6v.

I use them in my Naiant littlekit pre-amp to provide phantom power. They are the least expensive true 9.6 v batteries plus charger I have found.

Nice find, but I'm still doubtful that these are "true" 9.6V batteries. There's nothing in the specs promising this. And the 160mAh is untypically low. Maha and the others are all 200-230mAh.
But if you're able to fire them up to 10V, they should be good enough for most devices... :-)

I took the plunge and got the batteries and charger in 3 business days (to NY), ran 1 set for 2.25 hours and one set for 2.5 hours with no issues... 5th, I have a festival, so the real test then

[gmm6797]

FWIW, I already had one of the terminals "stay" connected to the charger when carefully removing the battery from the charger to take to a show.... so I have to see about an RMA and another 2 pack so I can not be stuck like this weekend where I needed 8 for a mini-festival and only had 7 available.

and, FWIW, they now havd a 300 mAh version:

Those are not 9.6 volts, they are 9 volts. They have been available for a while.

Ed, you try these out in your Aerco yet?

not quite ready to take the plunge myself, I still have a 6 month supply of throw aways sitting around.

I am no science teacher, but are we better off with more voltage or more mAh in the nbox?

nope
but they will work fine, tired of throwing away batteries
Nicky and i have been using them ok so far in the Nbox's

This has been discussed before. Search for "nbox + Maha".
Basically, the 300mAh version labeled 9V are actually nominally 8.4V. FWIW, Chris Church says they don't provide enough voltage for his gear, so he recommends the genuine 9.6V.

[Matt Quinn]

Any updates here? I am about to sell my V3 & go all Nbox, all the time. I'd love to get a rechargeable solution going.

[Craig T]

I've been using them for about 6 months with almost the same "program" as regular alkalines - 3 hrs on a freshly charged set, swap the pairs for another 3 hrs.  Yet to have a failure running this way.

[edtyre]

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 :-)
