Looking for a replacement rechargeable 9V battery for my amp. Are there any good, reliable quality high capacity 9Vs you can recommend?

the maha powerex 300 is a great battery,

however the low-discharge tysonic 9v is nice as if you listen like I do, an hour here, few hours there and take a few days off, it will keep its charge, unlike regular NiMH that lose their charge at a fast rate.

The Powerex 9.6v 230mah does a fine job in the D4. True 9v, rather than 8.4. Slightly more voltage than an alkaline 9v.

I was looking at the li-ion batteries, however the amp I have has a built in charger, so I figured it probably doesn't have the necessary protection circuit for charging li-ion batteries.

I'll look up the Tysonic 9V since that is pretty much how I use the amp.. I don't use it that often, especially since I'm still waiting for my opamps to show up already... and plus I don't listen to music quite as much as I used to ever since my HDD died. So yeah, having a battery that won't discharge when I'm not using it is a good idea.

Thanks for the replies!
