1 Cr2032 3 Volt Battery

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.

worked just like the product I replaced except uses a double A battery instead of a nine volt.

3 items that do the job.

1 stop is the right amount for me.

I do not believe I have ever reviewed a flashlight before. This one is a neat convenient package. Interesting too that it has a 9 volt battery. Works well with a rotating switch. I like it give it a try

This little flashlight packs a punch. The secret is in the 3.7 volt/ 2.4Wh 16340 with built in USB micro rechargeable port (on the battery). That battery gives this little flashlight a powerful long lasting bright beam. I'm glad that I purchased two of them. I keep one in my toolbox and the other in my car. Highly recommended.

Maybe this isn't quite what Sony had in mind for it's adapter. I use a 12 volt dc sealed cell battery, plug a 120 volt converter into that, then convert it back into dc with the Sony adapter. I do that for extreme extended battery use for astrophotography field use. It seems to work fine. There's no overheating in any part of my contraption, including the Sony Adapter.

The battery charger that came with my Canon Rebel was 110-Volt only. On a Smoky Mountain vacation, my installed battery went dead and there was simply no place to charge it. This charger allows you to charge the battery by way of the cigarette lighter. No more will a dead battery stop me from my photography and I thank the B&H people for leading me to this alternative battery charger

I use this to recharge the batteries for my Nikon D500. I have only charged two at the same time once - when I first received with two new batteries that were down to about 15%. I like the fact that it shows the capacity of the battery, each individually. There is also a port for charging a USB device (5 volt - 2A output) I have not used and it also came with a short cord to connect to the 12 volt outlet in the car so batteries can be charged on the way to or between shoots which might be necessary when using Nikon's adapter for wireless flash as it does pull the Nikon D500 battery down rather quickly.
