I bought some of the B&H batteries, the sleeves pulled out on my charger and or my 722. I went to Samy's cameras in LA and bought a pair of the new Lenmar batteries. They were mismarked at $92.95 (guessing but it was in the $90 range) guy said price was marked wrong and gave them to be at the lower price.Package says a single full discharge will give maximum battery life.After a full 24 charge I placed it on my 722 and powered my AKG414s via phantom. Got about 9+ hrs on intial charge. (Not all at once) did it over 4 times. After batteries hit 6.9 volts drop to 6.5 was fairly quick - approx 1 hr. This was on the intial charge. If they packaging is correct I should get a longer life on the next use.Q
just ordered 2 from amazon for 50 each

i charged one up last night and then tried to run it down compeletely (like the directions said) by sending it a signal all night. the thing still hadn't dipped below 7v in 5 hours. not sure how long it lasted, though (I went to bed)
Also, did someone make you a custom cable to use with your 744?

That's what I've done to get run times.At what point do people retire the L series batteries? Does the voltage just creep up to the point where it reports a high number like 7.9 and dies or what?

Does the voltage just creep up to the point where it reports a high number like 7.9 and dies or what?it recorded for a few hours, then i stopped it, erased the drive, and let it record until it died. I guess I can look to see how many hours it recorded the second timeand i retired my old batteries because they'd say 8.0 or 8.1 when fully charged, but quickly drop to 7.4 or so after just a few minutes. they're from feb 2005, so I got a good 5.5+ years out of them
i started recording 4 channels (line in) last night a little before 11pm. when I left for work at 7:30am this morning, it was still going and the battery was at 6.8v. that's 8.5 hours of 4 channels and it wasn't dead yet
610 minutes. 10 hours and 10 minutes of 4 channel line in, no phantom, lights and backlight on. so digi in with the lights off or stealth mode will run forever
when do you decide its time to switch batter (say ur at a festival of xmas jam etc) what voltage is too low?a
