Summary: Sony NPFS11 Camcorder Battery
Review: I was reading the reviews about this battery and saw how many people are facing the same problem. I would like to be added to the list of people complaining as I have (for a long time) had the same problem with these batteries. I have a Sony DSC-F505. I hope Sony will soon come out with a solution to our problem although I doubt it.

Summary: Poor longevity
Review: I'm a little upset that I have to replace this battery after just two years light use. It's probably been recharged around 30 times and now won't hold a charge at all.

Summary: DSC-P1 camara nattery issue and 3rd party options?
Review: I'm joining the list of annoyed Sony customers. I've had the problem all along and put it down to something I'd done wrong (charging to often etc)... looks like that is not the case :-( I'm going to try and send the lot back to Sony as per their suggestion on sony.com.Anyone had luck with 3rd party batteries in the same camera (I have the DSC-P1)? I tried a durracell replacement and it just wouldn't charge at all.

Summary: They have risen from the dead!
Review: I've had exactly the same problems as everyone else... I have two InfoLithium NPFS11 batteries which have been apparently less and less able to hold a charge as time goes on. I reached the point where I wouldn't even bother to take my Sony DSC-P1 out with me anymore! The batteries would last for two or three pictures then the camera would shut itself off. Thank goodness I found these reviews! I was about to buy two new replacements, having no idea that EVERYONE has the same problem with these batteries. I followed the prevailing advice and sure enough the results are a spectacular reversal of fortunes - a saving of almost $100! I killed one battery by taking picture after picture with the flash . I eventually got to 114 pictures at 640 pixel resolution, having to switch the camera on again (probably 8 or 9 times) when the "battery life" indicator came on and powered down the camera. Ignoring what the camera's telling you will mean that you will continue taking pictures for a long time. The camera actually gets HOT it's being used so much! Eventually the camera goes REALLY dead and the lens won't retract. Now I'm recharging the battery, pretty confident that the old battery will be rejuvinated to it's formerly effective self. This is exactly the advice given in the other reviews. HOWEVER... for the second battery, rather than trying to quickly start taking photos BEFORE the battery life is calculated by the camera/battery, I let the calculation go ahead first. The camera indicated that the battery life was 80 minutes. I immediately started taking pictures and got up to 190 pictures (using the flash). Again, the camera got quite hot in the time it took to take all those pictures. And even after all that time and all those pictures the camera showed that this second battery STILL had 45 minutes left in it! Odd. What I'm thinking is that it MIGHT not be entirely necessary to "kill" your battery in order to make it work properly. Maybe what you need to do - to kick your battery in the pants - is just take picture after picture for a few minutes as soon as you turn the camera on and it'll reset the INFO part of the battery! Worth a try. Obviously, you might need to do this every 6-8 months or when you notice the performance dropping off. Already this second battery is behaving like it used to - even without killing it. I have a hypothesis about the problem and why this "treatment" of your battery might breath new life into it. We tend to use our cameras in a very specific way that may be foiling the functionality of the InfoLithium system. We turn on the camera in preparation for taking pictures but it could be several minutes before we take a single picture. And we tend not to take pictures in rapid succession once we start. I think this cycle of switching the camera on, then doing little or nothing with it makes the battery go into some kind of "info-coma" after repeating this pattern for a long time! I wonder if the way this technology was developed failed to take this real-world factor into consideration. I speculate that the laboratory testing of this device probably involved discharging the battery immediately after the battery life indication had been calculated. Maybe that process is what the battery needs to calibrate itself. After months of never receiving that treatment it's possible that the battery no longer "knows" what the hell's going on!! I'd be curious to know if other people have the same results as I have. Email me if you like at nowis@sbcglobal.net

Summary: Thought it was just me !!!
Review: I, too, have had a bad experience with my NP-FS11. The first one died just over a year after I bought the camera (DSC-P1). I bought a second one and it died about 3 months afterward !!! I don't know if this is because of the camera or the battery. I have been thinking about getting my 3rd battery but lucky that I saw these reviews from Amazon.com. I may just hold off getting a new battery if this problem seems to be too common. After all it ain't cheap !!!

Summary: Ugh - Low Life!
Review: Like the other reviewers, the NP-FS11 that came with our DCR-PC5 camcorder stopped taking a charge after about 18 months. This is with very limited usage (maybe we've recorded a total of 3 hours of tape - and taken a few hundred digital still photos.) I have not bothered contacting Sony, but am thinking that I might need to spend a bit more on the NP-FS21 or NP-FS31 to see if I can get around this problem in the future. Doesn't look like replacing my NP-FS11 will be worth it based on everyone elses' experience.

Summary: A new tip for renewing the dead battery.
Review: OK, I came to Amazon hoping to just buy a replacement battery for my DSC-P1 and found that everyone here has the same problem I had. So I took someone's advice below and set out to drain the battery before the InfoLithium computer kicked in and stopped my fun. What I found though is that resetting the battery is a lot easier. I took about 15 pictures before the battery indicator appeared. I then realized that I was taking huge pictures and running out of memory stick space, so I paused. The battery indicator kicked in and showed 80 minutes. As I took more pictures and connected the camera to my Mac for awhile, the indicator showed nominal battery drainage and seems to be back in sync. This was a battery that seemed to be unable to hold a charge for more than three or four photos, with or without flash. So before giving up on your battery, try a quick refresh! I gave this 3 stars because it's lame that the problem kept me from using this camera for more than a year, but it was easily fixed once I knew what to do.

Summary: [$$$] and bad battery.
Review: One year of use and the battery is dead...
I have a Sony DSC-P1 digital camera. After 2 hours charging, the battery shows 87 minutes left but it is really able to take some pictures. Too many people is having similar problems with this battery, I don't recommend you buying the original one, instead there is a more reliable alternative [...].

Summary: Some success with these hateful batteries
Review: So after being frustrated with both the batteries and SONY support, I set up the camera to be as battery-intensive as I could, like so: DSC505V -LCD screen: maximum brightness white balance on, flash on and on high(+) with forced flash(lightning bolt), solarize filter on, AE on with moon and + symbol and the lenscap on...(this makes the flash even brighter) (sorry for lame technical terms. I figured this would drain the battery as much as possible... Then I fired off (get this) over 200 flash shots (of nothing) on a battery showing the low-batt indicator the whole time !! I did this untill the battery would no longer even start the camera. It charged for about an hour and a half and now it works fine!! I hope this works for you too!!
