Scale Battery Cr2032

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.

Lovely grey scale!

It's a 5 on the Zone System scale!

Provides solid power like any high end battery but it is so light and small. I wish the picture for it included something for scale. The unboxing experience was full of weird feelings because this thing is so tiny. TSA also likes it more. My other batteries show up as solid black cubes in the x-ray but this one doesn't and so it reduced the amount of times I am pulled aside when flying. If you travel a lot that is a bonus.

With the up-scale 3-color LCD backlighting, "Smart Battery" (temperature compensated) charging management and dual conversion technology, this is almost certainly the best performing 120V, NEMA 5-15P plug UPS available. Extended run battery shelves are available, too!

Past battery chargers used an LED color scale or series of LEDs to tell me the charge. That meant it wasn't until I put the battery in the camera I could see what percent of charge the battery really has. The Watson battery charger uses a percent scale just like my camera would and I can charge a single or two batteries if I need to. Yes it is bigger than a typical wall charger but great when you're traveling and taking lots of photos.

great grey scale tones

The most economical film which by the way gives an excellent gray scale.

Perfect for small scale green screen use.
