*the amp requires an 8.4V (or higher)*

this is what I got:

I'm not sure because the seller says:

One brand new 8.4 volt Powerex rechargeable battery (as pictured). Item specifications: -True 9v 300 mAh rating

That particular battery will be fine for an amp requiring an 8.4V (or higher) power source.

"9V" batteries are a series of cells, each cell adding a nominal 1.2V to the voltage rating of the battery. If a "9V" battery contains 7 cells, it is an 8.4V "9V" battery. Other "9V" batteries contain 8 cells, and are 9.6V "9V" batteries. This particular battery contains 7 cells, and so it is an 8.4V "9V" battery. When it is freshly charged, its actual voltage will be closer to 10V than 9V, and, with use, the voltage gradually declines to well under 9V. This is the expected performance of a 7 cell, 8.4V, "9V" battery.

thanks man!

x2. For "8.4V" batteries the voltage range depending on the charge remaining varies from 9.8V to 7.8V roughly. So, it is safer and more natural to use "8.4V" batteries instead of alkaline 9V than "9.6V".
