Battery Number 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.

The 4-pack is a good idea. I have a number of devices that use this battery.

Not much you can say about a battery except that it works, I’m not sure how to calibrate whether I’m getting the advertised number of shots, but the Fujifilm battery appears to give me enough.

OEM camera batteries (or an approved equivalent from a reputable dealer such as this Watson) aren't cheap. Like a lot of you (I assume...), I've bought my share of affordable batteries from other sources (i.e. on-line auction site) at prices almost too good to be true. The truth is I should have used that money on quality non-knockoff product, or a bottle of wine. The knockoffs are complete counterfeits with identical packaging, product labeling... and almost no way of knowing they're fakes until it comes to actual battery life / number of shots. Here's where the rubber hits the road (numbers not actual data, just for illustrative purposes); if let's say with the $20 counterfeit I was getting 40 shots before failure, with the Watson I am getting 280. 7 times the difference. However, pricewise the OEM was only 2.5 times more expensive. Considering the inconvenience, number of batteries necessary needed to have on hand, risk of missing a shot, and just the frustration of Darn! Battery dead again?!! (substitute darn with a much more forceful word) I've learned my lesson. Always, always by the quality battery. This one counts...

B&H are number one!

It's number one.

I have a number of Profoto B1 and B1X heads and was happy when this higher capacity battery was announced together with the B1X head, while being fully compatible with the older B1 heads. The battery also has an LED bar indicating its charge, which is very handy when the battery is not on the strobe and you want to quickly check battery charge status.

The Canon battery was not available so I purchased the Watson equivalent. It works great and I have not noticed a drop in the number of images available with this battery powering my camera. I cannot speak to the longevity of the battery because I have only had it a short time. I think it is an excellent replacement battery.

This battery is far more expensive than any number of 3rd party batteries you could find, but the thing works beautifully. When you need to know exactly how much time / charge you're gonna get out of your battery (and need to count on rechargablility without losing capacity) there really is no other option. If you are shooting stuff you can't afford to miss or lose due to battery failure, the Canon brand extra long battery is the absolute best.
