Amazon Cr2032 3V Batteries

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.

These are, as far as I can tell, the only rechargeables on the market that are 100% compatible with equipment that needs 3V CR123A batteries, and they are only available from B&H. Too bad about the lack of choice, but they do work very well and the capacity is as stated. I use these in my August lock, where it saves me a fortune, since the lock is hard on batteries. I also use the smaller CR2 batteries in various smart home sensors, where they likewise result in significant savings over the long run.

I have a Streamlight Polytac flashlight that only accepts 3v cr123 batteries. all other rechargeable cr123 batteries are 3.7v which is too much voltage, but these Watson batteries work great. I love how these Watson batteries came completely sealed. B&H photo seems like the only place that carries them. I hope they don't ever stop!

only been in use for the last week .... All seems excellent... NO issues yet .... I think these Watson 3V CR123A Lithium Batteries are protected were as I am unable to over charge the battery by leaving the battery in the charger, if this is the case ..... then this Watson Dual Rapid Charger and Watson 3V CR123A rechargable batteries are excellent for my device.

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.

It's a good battery, it's authentic, and don't ever buy your batteries from Amazon because they're going to be fakes.

The DC-3V Directors Case by Porta Brace is the best laptop bag that I have ever purchased. I am a Videographer that likes efficiency, durability, versatility and overall top quality for a great deal. This product has it all. Everything from its durability in materials used, all its pockets that easily allows quick access and efficient organization, and the versatility for not only the laptop, but anything that you need to store in the bag for any reason, there are plenty of pockets for all to be used. The handles and shoulder strap feature a super soft suede pad for comfortable carrying. Overall, this product has everything that I look for in a hearty product. Of course I would recommend this to anyone who is looking for a sturdy laptop bag.

We use this battery adapter with a 14v system via D-Tap plug. The DC adapter drops the 14v down to 3v. We use the power from a Steadicam Flyer sled to power this power adapter which then powers wireless Sennheiser receiver. Very easy to use and one could add pretty much any type of power connection that ranged 14v-8v (I believe) down to 3v to this adapter. Be blessed, Frederick Marbelle

My Canon branded batteries always died within a year, and the cheap amazon options were never reliable. Two of these lasted all day shooting video on a 5D IV, and are much cheaper than the OEMs. Highly recommend.

use genuine batteries, they last 4+ hours depending on how many pics and vids you take. i have tried the knock off cheap ebay and amazon batteries. they only last about an hour each.
