Button Battery Cr2032 3V Weight Grams

only been in use for the last week .... All seems excellent... NO issues yet .... I think these Watson 3V CR123A Lithium Batteries are protected were as I am unable to over charge the battery by leaving the battery in the charger, if this is the case ..... then this Watson Dual Rapid Charger and Watson 3V CR123A rechargable batteries are excellent for my device.

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.

We use this battery adapter with a 14v system via D-Tap plug. The DC adapter drops the 14v down to 3v. We use the power from a Steadicam Flyer sled to power this power adapter which then powers wireless Sennheiser receiver. Very easy to use and one could add pretty much any type of power connection that ranged 14v-8v (I believe) down to 3v to this adapter. Be blessed, Frederick Marbelle

The Leica 50mm Summilux-M ASPH f/1.4 is the most sold and most used lens in recent years. Perfect industrial design of the barrel (on the normal version) and ideal optics for an all-round standard lens. For me, the extra kick is this lens in classic design, but with the qualities of the current ASPH design. The weight is 448 grams (and not as BH are stating) 335 grams (which is the weight of the normal 50mm ASPH in black). I try to live with the extra weight for reasons of classical design, and I also hope the value goes up as it did with the limited LHSA edition from 2005. Should I ever sell it, that is. On filters, it IS actually possible to lock a 43mm filter into the lens via the front of the shade. For UV it doesn't make much sense, but for ND it does make sense to have both shade and filter on. I have made an illustration of the work-around here:http://www.overgaard.dk/leica-50mm-Summilux-M-ASPH-f-14-APO.html

Effectively conceived and engineered little tripod, that excels in weight and portability. It's particularly convenient for specific uses (tabletop and/or low-angle shots) and obviously isn't meant to replace taller, heavier tripods. I was particularly impressed with its eco-friendly packing materials, i.e. only cardboard and paper, no plastic. For the accuracy-minded: The head unscrews very easily (I plan to use it on a lightweight CF tripod as well), the fixed screw into which the head screws is 3/8 inch, the weight of the tripod alone is 517 grams, the head is 165 grams, and the quick release plate is 23 grams, totaling 705 grams.

Although newly received, I couldn’t wait to provide a positive review. This headlamp is perfectly sized, light weight, easy to use, intuitive, and well made. My favorite feature(s) are first, its size. It is diminutive but I am drawn to it. Perfect for every day use and can be stashed in a pocket or bag without taking up valuable space. No reason not to keep it with you all the time. It is super light weight and can be worn for long periods without hardly noticing its there. Although packed with (a ton) of features, it is not so complicated that it is hard to use. Cycle through the large, easy to find/locate power button on the right side for desired brightness, adjust or focus the beam by turning the bezel (if needed), then tilt the light in its removable head strap. Easy! I really like that the first mode (brightness) is medium (then high then low) and after the light has been on for 5 seconds, an additional push of the mode button cycles the unit to off without having to scroll through the different brightness’ again. Rechargeable!!! I can’t stand tossing battery after battery and have switched all of my lights to rechargeable. Power for days! On last use, I kept the light on (medium) for an easy 2-3 hours with no discernible change in performance. And, if curious, the mode button also has a lighted battery indicator. Green is good to go! If it was low, I would know. (Ha!). Magnetic base, dust proof and water resistant. All the boxes are checked here. All at a great price and with the outstanding Coast Lifetime Warranty. If I had one wish, I would ask for an ultra low(10-20? lumen) mode (in addition to the others) for reading in the dark. This light is so good, I’ve got mine on right now. Get one, give one. You’ll be glad you did. Go Team Coast!

It's cheap. Comes with battery. Press the button and that's it. Perfect.

The DC-3V Directors Case by Porta Brace is the best laptop bag that I have ever purchased. I am a Videographer that likes efficiency, durability, versatility and overall top quality for a great deal. This product has it all. Everything from its durability in materials used, all its pockets that easily allows quick access and efficient organization, and the versatility for not only the laptop, but anything that you need to store in the bag for any reason, there are plenty of pockets for all to be used. The handles and shoulder strap feature a super soft suede pad for comfortable carrying. Overall, this product has everything that I look for in a hearty product. Of course I would recommend this to anyone who is looking for a sturdy laptop bag.

These are, as far as I can tell, the only rechargeables on the market that are 100% compatible with equipment that needs 3V CR123A batteries, and they are only available from B&H. Too bad about the lack of choice, but they do work very well and the capacity is as stated. I use these in my August lock, where it saves me a fortune, since the lock is hard on batteries. I also use the smaller CR2 batteries in various smart home sensors, where they likewise result in significant savings over the long run.
