Is It Possible To Use A Third-party Info-lithium Replacement Battery In A Sony Digital Camera?
Hi! Please…I have a SONY DSC-S50 Cyber-shot digital camera, and I believe it’s time for a battery replacement. The model number on my battery is: NP-FM50. This battery is the original battery and it came with the camera. It’s labled as an “infolithium” battery. Please, is it mandatory that I order a SONY replacement battery, in particular, or am I safe in ordering a compatible lithium battery online or elsewhere? If so, which online site is recommended? One site suggested that sometimes third-party batteries don’t always work in SONY digital cameras. Sony, naturally, suggests that I use their brand of accessories. I am still quite the novice and any/all advice regarding this subject will be greatly appreciated! Thank you! 
I’ve had luck using compatible batteries for my old Sony digicam. But I heard that the newer Sonys have a way of checking if the battery is a genuine Sony infolithium battery.
Best to work with a local seller that has a good return policy – such as Best Buy or Circuit City.
I personally buy most of my rechargable batteries from Thomas Distributing:http://store.thomas-distributing.com/dis…
I’ve also had good luck with Battery Barn:http://www.batterybarn.com/npfm50.htm
If I am not wrong this camera is already qiute old in the market already. If purchase a original battery it will cost quite a sum of money but from what I known using a compatible battery should not be a problem as only the newer cameras that is produce after DSC-T9 will have a problem using compatible one. For that battery only the more expensive handycam such as DCR-HC3 is using none of the camreas and handy-cam is using it anymore. If possible i will recommend u to purchase a new camrea instead.
Yes and they are generally cheaper and last longer because they have a higher mAh. You can either Google it or check out eBay to either buy them on line or to find out the web site of the company selling them. There are a lot of companies out there who do nothing but make replacement batteries for cameras, laptops, PDAs, etc.
