Cr2032 Battery The Source

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.

Most solid and stable power source from a battery with d-tap.

Nitecore 18650 Li-Ion Rechargeable Battery is a great source of stored energy. Being rechargeable makes this battery cost effective. This Nitecore Li-Ion battery has demonstrated its dependability in a flashlight over a period of seven hours of intermittent use. Great product!

I like that I can charge my battery on this instead of connecting my Sony A6000 with battery in it to a power source (it's a pain). No complaints, works well!

This Sony Style battery is great power source for my Black Magic 7, 3G Video Assist. Two Batteries on the BM unit give your plenty of record /PlayBack time. I also purchased the Watson charger. I will buy more of these batteries as money become available. I can wholeheartedly recommend them.

This is the best investment as my camera power source. This battery lasts a long time and it charges with a cable directly pugged into it. I do not need to carry a charger because of that. Great value for your money.

The Nanlite is a well designed, and well made light source with an integrated rechargeable battery. I use it both for live casting as a key light, and also for low level landscape lighting and light painting in a variety of environments and ambient light levels.

I bought the EchFlow Delta 2 Max with an extra battery. Looking as a backup power source when/if the power goes out. Tested it on various small to medium household appliances and it worked excellent and charged it up every fast. Ready for another use. I also bought last year the Delta Pro with two extra batteries was able to power two refrigerators for 24hrs before needing to charge. Looking forward to making some solar panel purchases next.

When shooting stills or video for an extended period with a USB power source, the internal battery still supplies 20% or more of the current, and lasts only about 5 hours. Furthermore, USB connections are small and subject to excessive wear. This battery substitute runs from a large 14 V video battery through a D-Tap connection, and is regulated to provide the full 7.2 VDC required by the camera.
