Moosh is bad.
Feminine undergarments being thrown on stage from the audience is better, in theory.
3,000 hours battery life sounds more like normal. I'm not sure if the pot value could have an effect on battery life, but it will affect tone. Vaules are usually stamped on the can unless someone soldered over it. You can always check it with a multimeter. I found a thread on Talkbass where people were saying the pot value isn't really critical. EMG supplies 25k, some people like 100k better, 250k will work. I just know that with passive guitar pups, a 500k pot can make single coils sound anemic.
On a more subjective note, a buddy of mine has a P-bass he put an EMG in years ago. Works fine, but I never thought it was all that special. Another friend bought a 5 string P-bass and put a Nordstrand (passive) in it. Huge booty for days on end. Totally different animal.
