how old are those batts? you should get waaaay more runtime than 2:10!!! something is wrong there. do you have your backlight turned to go off in 3 secs? that could be a factor
i ran mine on 2 internals last night that have been used countless times, and i still had 3 bars left after 2 sets of 1:15+...
Both batts are a year old. something is really wrong w/ them. I had no problems at all until about a month ago. I taped a moe. show, and still had 2 bars. I even listened to it on the way home from the show, and the next day at work. I charged them again, took them to tape some local stuff, and they died out on me. I thought something must be wrong, but hoped it was a one time thing. It wasnt. Full charges only get me about 2+hrs now. I've tried cycling the batts, but nothing worked.
Oh, I turn the backlight completely off, IR sensor is off, volume down to zero... everything necessary.
I bought my JB3 re-furbished, maybe the batt that came w/ it was junk. The other was bought new from an online retailer. Like I said, no problems until last month.
Hopefully the Power Plant batt will solve it, and I wont have to deal w/ it anymore.
