Simple question.

What is the best recharageable battery for a portable headphone amp?


I find that lithium 9V batteries give the best power for my Headsix. Followed by normal brand-name alkaline; Followed by generic 9V alkaline; Followed by my rechargeable 9V.

Are there Higher Quality rechargeable batteries or am I stuck buying lithium batteries, like a bottle of wine, for special occasions?

I've often wondered the same thing. I know ray Samuels discourages using some types' batteries in his amps. But I normally use rechargeable Ipower batteries and a few disposable lithiums for the Hornet, but only because on his website, Ray says the disposable lithiums give a really long life.

I've trying to find someone who sells a rechargeable 9V battery for my Meier amps but I can't find it in my country, don't know why.

I found some sellers, like I power US, but they don't ship abroad. Does anyone know someone who can ship 2 batteries and a recharger for me? I really want to get those lithium batteries...

Standard 9V batteries actually put out 8.4V, not 9V even though that's what they're called. Here's a battery from Powerex that puts out 9.6V: MAHA / POWEREX 9.6V 230mAh Rechargeable NiMH Battery

but aren't these batteries a little longer than regular ones?

 

[MatthewK]

Not that I'm aware of. I just put it up to a regular 9V battery and it looks about the same length to me.

I use an Ultralife lithium 9v in my Zen Head ZH1, it is a tight fit as this battery is very slightly longer & thicker, but it does fit. I wrap a piece of ribbon around the middle of the battery, just long enough to give me a pull tab by grabbing the two ends(of the ribbon), before I push the battery into its compartment. This is a non-rechargeable battery, but I suppose some re-chargeable types may also be a little longer.

I like the Tysonic low discharge 9 volt by far. It has the same type of low internal resistance of the eneloop batteries, which mean a better power supply, which equates to better dynamics, more transparency and finer detail because of cleaner current delivery.

interesting choice

X2. I took Jamato8's advice and bought these for my SR-71A. Maybe not the longest battery life, but for sure the finest sounding 9V I've heard.

I also live aboard and recently brought the Codra 3Move, and have been looking up rechargable 9V lithium battery and charger too. I may not need this afterall, as I am thinking of changing direction and selling my 3Move as new, but here is one that apparantly ship to many countries:

Anyone have an Idea about battery chargers, any charger for NiMH batteries will be fine??

 

[Demonmnky]

I would assume a NiMH charger is a NiMH charger and the batteries are built to be charged by them. Please correct me if I'm wrong.

Thanks to everyone for their suggestions. I have some buying and trying to do!

 

[Nicolas2305]

Do you guys know if Energizer rechargeable batteries are any good? Because Tysonic batteries shipping is like $15 to Canada.

 

[Tranzaddict]

This 9V charger can charge both the NIMH and LI-poly batteries which is nice if you have both types.
