2.0 out of 5 stars NP-FS11 is no good, or is it?, November 27, 2002

By A Customer

This review is from: Sony NPFS11 Digital Camera Battery (Electronics)

Apparently a lot of users have problems with this battery.
I own a Sony DSC-P1 digital camera, and always use the simple power connector to reload the camera. A friend also owns a DSC-P1 and has exactly the same problems: the display will say the battery is full (>90 minutes left), but when you start using it, it will stop after < 10 minutes of use. This really sucks.
I've searched the Internet all over for solutions for this problem, and there seems to be none. Apart from Sony denying there's anything wrong with the batteries (or the camera!), I've found some 'workarounds' (including advice from Sony) that don't really work.
- Fully discharge the battery. Keep turning your camera on 'till the battery is completely empty. (Doesn't work).
- Check the connections (Sony advice) Clean the connectors of the AC powercord (Doesn't work).
The only thing I didn't test, is a very expensive Sony quickcharger. I've used them occasionaly, and they seemed to recharge the battery very well (giving cause for a camera malfunction/flaw scenario). Does anyone have experience with the -far too expensive- quickcharger?
I used to be a real Sony fan (2 VAIO's, VCR, LCD-monitor, digital camera, Digital Video camera) but now I really hate their attitude.
They charge WAY too much for accesoires and spare parts. I paid 40 euro for a simple I-link cable; my video LCD broke down (cat-chase fly-drop camera) and it will cost me about 400 euro to repair it; a quickcharger will cost you about 200 euro.
This really insults my intelligence! I hope they'll switch to a different marketing strategy very soon, or they'll lose me forever.

1.0 out of 5 stars Help For This Battery, February 22, 2004

By A Customer

This review is from: Sony NPFS11 Digital Camera Battery (Electronics)

I signed on looking for this battery and noticed everyone had the same problem. I also have the Sony DSC-P1. Taking "Canada's " advice I killed the battery. You should set the flash to on. After you turn on the camera and the flash is charged take a picture right away and continue doing this as soon as the charge light is steady. I took 150 pictures this way(2 64 meg cards) on a socalled dead battery. Don't give the battery indicater a chance to come on. This battery used to charge in 4 minutes and die in 3.:). After I killed the battery to the point it didn't have the energy to pull the lens back in, it took 2 hours to charge and hasn't died yet! I don't think the battery itself has memory, I think it has a problem with the info part that tells the camera how much powers left and it fools the camera into shuting off. Hope this helps all. It helped both my batteries.

This review is from: Sony NPFS11 Digital Camera Battery (Electronics)

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 [e-mail]
