lifespan of batteries? | Headphone Reviews and Discussion - Head-Fi.org

I've got three, 9v NiMH rechargeables, 270 maH, 300 mah, and a Powerex 9.6v 230 MaH. They all charge a fully maxxed, all switches "on" Portaphile. I get the most life out of the Powerex 9.6v 230 Mah.

So here's the question: is the longer life of this battery due to the 9.6 volts, the lower mah at 230, or a combination?

The least lifespan is the 270 t about 1 1/2 hrs. vs. the 9.6v at almost 3 to 3 1/2

Would love someone to explain this.

More mA means more lifetime. Voltage has nothing to do with that. I don't see how your 230mA battery could give more life compared to the 270 one. I for one get about 2.5-3 times more lifetime out of my 9V 500mA Li-Polymer batteries compared to the Energizer 175mA ones. It could be some batteries aren't functioning properly and/or they aren't fully charged as you may think you are.
