Keychain 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.

I like this keychain light.

Great for your keychain!

Unobtrusive on the keychain and used more than you'd think.

The best keychain I ever had

Pulled it out of the box, comes with a remote, a keychain clip and a wrist strap to hang it off, a camera cable and a receiver. The receiver fit the hotshoe on my 500D/T1i perfectly, almost no play and very secure.It works flawlessly where ever I try it. Inside, outside, in the country, in town, everywhere. You have several shooting options on the remote: Single or bulb, 2 Second Delay and Continuous. Also, it is possible to configure multiple receivers to trigger off a single remote.The receiver runs off a standard CR2 battery, and can also be used to trigger the camera manually if there is no battery in the receiver.The kit is also upgradeable if you change camera systems simply by buying the appropriate cable (Available on B&H for a very reasonable $6.95).I would have liked some way of mounting it that didn't sacrifice the hot shoe, but for this price I can get by without it.I am very impressed with the value for money this kit represents, and I will be recommending it to all of my friends until they tell me to shut up.

Wow! Incredibly bright light from a keychain flashlight. Uses one AAA battery for easy replacement.

I keep this as a backup on my keys. It is everything you want in a keychain flashlight. Its bright, light, and durable. Battery is excellent and requires little charging time!

Got this with another purchase. Great for what it is. Runs off a AAA battery and is about as bright as a smartphone flash. It's keychain sized.
