Button Batteries 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.

Surprisingly bright and uses 1xAAA which I prefer to button cell batteries as I usually have extra around if needed. Flashlight is the perfect size for a keychain. It turns on and off by rotating the front as opposed to a button which I think will also prevent accidental battery drain from errant button pushes.

Holds 2 batteries and has worked flawlessly for me so far. Admittedly, I don't use the included shutter button or cable. I shoot video and this unit does what it's supposed to do.

This is an amazing laser for playing with cats. The AAA batteries last Easy longer than the little button batteries. The switch is press on, press off, so you don't need to hold the button constantly. It turns on and off reliably, unlike the cheap lasers. It is bright enough to work in the daytime. I suspect I'll be saving the price of this laser in one year just in batteries. Lion King approves!

This feels like a flashlight that you can rely on. The mechanical push-button tail switch is a great feature and it uses AA batteries. I have mine loaded with lithium AA batteries and stored in my emergency kit, so I can be sure that any time I need a flashlight in the next 20 years, this one will be ready to go.

This is a very bright and durable flashlight. The flash light uses batteries quickly, but I use rechargeable batteries. The only down fall for the flashlight is the on and off button.

It does the job. The batteries are easy to get in and out, and never fall out on their own. I use rechargeable Eneloops, button up for fully charged and button down for needs recharge. It's a great system to keep things organized.

This is a very compact, bright flashlight. It's nice that it uses a single AAA battery too instead of those expensive button batteries.

Though there is not battery built in I really like the grip and the second shutter button. Good thing about no battery built in is if you have extra batteries you can swap them out easily when it runs out. I really like this.
