Cr2032 Watch Battery Making A Whistling Noise

I run through a bunch of CR2032 batteries every couple of months. I like these because battery life has been good, and I can buy them at a reasonable price through B&H.

The RAYOVAC CR2032 Lithium Battery (2-Pack) contained two, count-em two CR2032 cells. Absolutely amazing!!. These were purchased as spares, so I have not measured their voltage yet. Presumably, they will produce the rated 3 Volts and will last for 190 to 240 mAh. They are 20 mm in diameter, shiny and light weight and most likely contains some lithium & manganese dioxide so are technically a LiMn02 cells. FYI: They can explode if heated to more than 80 deg. C.

The CyberPower UPS started making a high-pitched whining noise. It seemed that the battery had no more life in it so I replaced it with this replacement cartridge from B&H. It is now working again and I hope to get another 5-6 years out of it. It didn't come with a way to recycle the battery so I'm hoping to find somewhere local to dispose of the old battery pack.

I use this with my iPad or phone when others watch TV. It reduces the noise and I can hear better. Thumbs Up!

They really got it right with this powerful and feature rich projector, it leaves nothing missing! The projected image is really bright from edge to edge, but not blinding! It lets you watch even during the day, the color gamut is beautiful and rich, natural skin tones and vivid color. The picture is crisp, when properly focused (the focus wheel is a bit tight and located just below the HDMI port - this would be my only complaint!) with its full 1080p HD resolution even at the farthest projection, you don't see any pixels or noise (unless present in the projected image) This alone makes the P6X highly recommendable! What makes it nearly perfect: it has a real quality built with all the necessary connective ports, easy to use in the dark button menu and remote control, the 4 hour built-in battery that even doubles as a phone charger in a snap, it comes on almost instantly and doesn't get really hot, the fan noise is therefor barely noticeable! The built in speaker is not bad, but only indoors, for an outdoors movie night you might wanna connect external speakers (or use head phones!) This little machine gives me so much versatility to watch movies, connect a streaming device for TV, use it for presentations off your computer, show slideshows - even directly from your camera, use it for video art installations/multi media art shows. I love using it as a creative way to light a portrait shoot or add interest to a background...the options are endless... it goes with me in my gear kit, cos it really doesn't take up much space...if you haven't guessed it yet, I highly recommend this product and I've used and tested many projectors over the years, this one is a winner! It puts AAXA ahead of the pack!

I struggled with another brand--which is known for making good equipment--but I always had to watch how much weight I put on, and the height was very limited when using the boom.  The Avenger is many levels up from there and is SO solid.  It will put a light about 6 from the center post, about 12 in the air, leaving a short length for a counterbalance.  You should seriously consider getting the wheels, which are also heavy duty.  I HIGHLY recommend the set up.  I feel I can do so much more now, and that my lighting is not limited by the equipment.

Fast shipping from the other side of the U.S. and no issues at all with this RAM. The main thing to watch out for when purchasing RAM is making sure it's the right RAM for your machine, so I did my homework there. After that part, I purchased from B&H and had no concerns whatsoever.

This thing is great. The introduced noise level is nonexistent as far as I can tell. My wife and I use it to watch TV at night so we don't wake the kids. We can both plug in our favorite headphones/earbuds and control our own volume settings. I also use it in my office paired with an ART SplitMix4 to mix the sound from multiple computers to a single set of powered speakers. The +20dB gain is perfect to overcome the -12dB from the passive mixer, and still give a little oomph. I may buy a third one of these soon.

I use these new Rode headphones to quietly watch TV so no TV noise to interfere with wife if she is reading a book instead of watching TV with me. Great quality. Would purchase again.

I love shure products and wanted the best quality audio for voiceovers and podcasting while having the ability to stay mobile. The MV51 provides just that. I picked up two of these before the new year as they were $50 off so that I could use them for podcast style interviews. You can plug these into your computer, iPhone, or IPad making it extremely versatile. I recently conducted an interview at a coffee shop, pretty noisy, so background noise was still an issue, however the talent and interviewer voice was clean and above the noise making it extremely audible. The build quality is really nice with a modern/classic look. There’s a kick stand built and you can attach it to a stand if necessary (I recommend at least a table top stand). I’m super happy with the quality of the build and the results of the recordings I’m getting with this. No regrets at all.
