Sony NPFT1 InfoLithium Rechargeable Battery Pack for the DSC-T1, T5, T9, T10, T33, L1, and M1 Digital Cameras

Although there are (much) cheaper & higher capacity "generic" (non-OEM) batteries claiming to "meet or exceed the original manufacturer specifications" being sold (e.g. ebay), they may not always work. As a case in point, although I've tried several generics, I have not found a one which will work with Sony's new DSC-T9.Sony's "InfoLithium® technology" integrate a microchip which they claim: "ensures maximum battery life and maximum power". Unfortunately, Sony also uses this technology to stymie efforts to produce lower cost "generic" batteries by third parties.When cameras (using InfoLithium batteries) power-up they read the status of the battery and display the remaining battery life. If the camera cannot verify the battery condition (or authenticity?), it will display an error message and power down.Although more expensive and lower capacity than generics, this genuine Sony battery is guaranteed to work.

After I figured out my camera had become unplugged in its stand that recharges the battery it was fine. At first I thought it was bad, good thing I found the loose wire..

I don't know what to say about this product. It's a battery for my Sony camera. The camera is working fine now that I replaced the battery. What else to say? The service was good, as always is the case when you buy from, or through, amazon dot com.

I purchased this battery in Oct 2011 as a spare. I have only just opened up the packaging yesterday 27 June 2012, charged the battery and used it in my camera last night. The battery charged OK but when I put it in my camera it doesn't allow my camera to switch off. I could still take a photograph but afterwards had to remove the battery to switch the camera off and re-insert when I wanted to take another picture. I re-inserted my original, now re-charged, battery into the camera when I got home and the camera is working fine so there is no fault with my camera. Very disappointing as now due to the elapse of time I will not be able to return the battery for a replacement. A lesson there to test out new things when you get them before it's too late !Stop press 2 July 2012: I have now noted where the ridge is along the end of the battery (in front of the C in Cybershot) that the pink & grey wrapper was getting stuck in the ridge. I've torn that part of the wrapper away and the battery now seems to be working OK and not keeping the camera switched on constantly. Normally I don't have to remove the wrapper on previous purchased batteries but this seems to be working so is only a minor fault that worked out ok with a slight adjustment. I gave one star at first as I thought it was a dud but now it's working fine I'll promote it to a four !

These batteries with Sony's branding are good but they cost a lot more than generic batteries. It's up to the user to determine if the additional cost is worth it. I have had some swelling of generic batteries in the camera which is not good. So I paid the price.

I don't know what I can say about a battery... I will say that I'm glad that I found a NEW, authentic Sony battery on Amazon that was very inexpensive. The old battery served my camera well for 6+ years, I can't remember. I had to replace it with an authentic one. There are alot of knock off's out there that I was contemplating to buy, but I have read bad reviews on them. Hope this one serves me well until I get a new digital camera.

I am unfortunately out of the return window and I just went to use this battery. Cut it out of the plastic, charged it and put it in my phone. My camera says it IS NOT A LITHIUM BATTERY!!!! FAKE, FRAUDULENT, DO NOT WASTE YOUR MONEY., I CANNOT CONTACT THE SELLER AND AM VERY DISAPPOINTED!!! $40 down the drain!!!!! Clearly made in China. DO NOT BUY FROM THIS SELLER!! SELLS FAKES!!!

Purchased additional rechargeable batteries for a camera for when I was on vacation. Only problem was I left them in one of the hotel rooms at the of the vacation. But they did really work. Everyone should have several sets.
