      Comments about Watson NP-QM91 Lithium-Ion Battery Pack (7.4V, 4200mAh):

      Arrived with 55% charge, took 22 hours to charge fully on Pearstone dual charger, but ran my Marshall 7" camera-mounted video monitor for over 4 hours, which was 3 hours longer than earlier non-Panny batteries I bought. The Marshall is a power hog with no battery indicator, so power capacity is an important decision criteria for my use.So, it's very helpful to have the battery strength indicator on the battery itself, although it's often hard to press to engage it. It delays its readout for a moment, then reads up to four LED's to indicate power remaining. I wouldn't trust it past the two lower lights, however, because my monitor shut down after the batteries showed about 25% remaining power when tested on the Pearstone charger/tester (the two lower lights out of four were illuminated).Worked long enough to satisfy me, however, so no complaints. These are Watson brand, about which I know nothing. Neither did I know about Pearstone, which I think I purchased previously. I'm guessing these are generic items branded for B & H. Don't have enough experience yet with using these batts to know how many charges they will accept in their life cycle - too busy with other stuff to keep track anyway.Batts snap into charger plates and snap into standard Sony batt adapter plates. All very nice and snug. Engenders confidence and reliance.I know subsequent charging time was about an hour or so. Lost track of exact time. So, yeah, I would recommend these batts to a friend, even others who are not yet my friends. It should be just fine as a reliable power source. I was very impressed and pleased with its performance, no regrets.

      Will not charge on Sony Charger

        Comments about Watson NP-QM91 Lithium-Ion Battery Pack (7.4V, 4200mAh):

        After purchasing this battery, I found that this battery will not charge on 2 different Sony BC-VM10 Chargers.

        So, if you are considering purchasing this battery, with the experience I have had, I would strongly suggest purchasing the charger they recommend in the "recommended accessories" tab, because the Sony chargers will not charge off-brand batteries for some reason.

            It fits well on my Sony double-decker video light and allows me access to use either one or both lights depending on my filming needs. It is slightly heavy when it fits on the back and doesn't work the best with stability on a shoe mount attached to my Sony HD camcorder.

            Great battery....no need to pay for brand name here. These batteries are better than brand names. I bought it to power a 5" LCD monitor. It'll run the monitor all day. Whit the LED power meter you know just where your are.

              I use the battery on a Sony HVR-A1U camera. No need to run a electric cable to the camera because I have plenty of power for 2 - 3 hour shoots.
