ULTRALAST UL-F550 Sony L Type NP-F550, NP-F750 Equivalent Camcorder/ digital Camera Battery - ULF550

Terrible battery. not worth the price

10/13/2009

What can i say. This battery lied to me. It would show great batter life in the beginning, but faded fast. After a few months i couldn't even get 5 minutes of shooting out of it. Bought a true Sony battery and all is now fine. Stay away. I saved $30 but it cost me some priceless moments and wasn't worth it.

Died Young

8/11/2009

The original Sony batteries (made in Japan) lasted over 8 years. The Ultralast (made in China) barely made it a year. The original battery stopped charging when it was full. The Ultralast seems to just keep on charging, which may be the factor that shortens battery life. It worked great for a while, but is all but dead now. It died too young.

Sony Mavica camera gives 3.2" floppies new life

1/11/2009

This battery reinstates my use of a Sony Mavica digital camera which uses 3.5" floppies. The Sony had to be a lot bigger than today's little easy-to-lose flash memory chip-equipped products that are barely larger than the lcd screens they use to preview the shots. The whole cameras are now easy-to-lose! Whenever its time to slide the floppies in and out every 30 or so shots, I get to be Ansel Adams "booting" his Polaroid Land Camera... or it's just like loading those old Civil War one-shot deals with the glass plates; I get to play Matthew Brady - Civil War Photo-guy, but without the deadly-vapors-in-the-developing-tent stage of the artifact creation process <;-)... this old Mavica MVC-FD73 is about the size and feel of my long-retired and lost Minolta SRT-101 35mm SLR from high school yearbook days. It is great in low-light without the flash, focuses down to 2.5" from any subject and has 10X Optical zoom plus several preset art FX's like "posterize." What fun! And the "stamina" sales point about 2 1/2 hours from an infoLithium battery just got doubled with this replacement battery. The first charge gave me over four hours of juice that the Mavica reads out as "minutes remaining" with great accuracy. Here's to "a pocket full of floppies!"

Good battery so far

Battery is good so far. It was the right one for my camcorder model, the SONY DCR-TRV9. Unfortunately it turns out the camcorder is dying, so I won't be able to tell if the battery will last over time...
