As to those who have Wasabi batteries that don't hold charge etc. Yes, you may have gotten bad ones, it happens. Or they may been sitting in a warehouse too long. You may not be following the "best practices" for use and care of rechargeable batteries. Google it and read up one it. charging too often, letting it die and then sit etc etc all bad ideas. Batteries are like other tech, there are good ways and bad ways to use them.
You can also google for how to recondition rechageable batteries, it works pretty well, I have done it. Toshiba used to have it on their laptop support menu. I once tried it with an old Toshiba laptop battery that had been on a shelf for about 2 years, only held 20 min charge (3+ hours when new, yes, a long time ago-90s). After a couple of days following the instructions for reconditioning I got it back up to almost 2 hours. I used to do the same thing with a rechargeable flashlight. The instructions for reconditioning the flashlight came from a police forum, seems many cops were using the dash mounted charger in their patrol car as a storage rack for the flashlights, batteries were getting where they died after a few minutes.
One main thing if doing the reconditioning, if the item the battery is in has an auto off feature to save power, kill it and turn the unit on and let it totally drain for a day or two, turn off for an hour or so, turn back on and let it die again (probably only a few minutes), then charge it fully and about 1 hour beyond the indicator saying 100%. Go through the whole drain sequence again, recharge, repeat at least 3 times. And DO NOT LEAVE CHARGING, no matter what some say about different types of batteries developing/not developing a memory or over charging protection circuits etc, take them off after they are charged. I got that from a factory tech dept manager when I contacted them about my tablet not holding as long a charge as it used to. Among other things he stated that the little charge protection circuits* were often cheaply made and not reliable. So give it 10-60 minutes beyond full charge and then take it off charge and either turn it off or use it. Spare batteries need to be checked every so often to see how much charge they still have and he said never recharge if still above 40%, better yet 20-30% or use the battery and then recharge.
This seems to have worked so far.

*over charging can produce heat and that is what swells the battery case and can produce a fire. I left a rechargeable electric razor on the charger once and found the thing totally deformed, and HOT. Some of the higher grade and price devices have quality charge protection circuits that do work. But unless you want to find out if a given device has a good one the hard way, just take it off charge when it indicates full.

They're just good. I've used them in Canon and Nikon bodies. No problems.

I'm (at son's house, for Christmas) 1300 miles from home, and rather than try to find room in my carry-on for a charger for my recently acquired Fuji; I just had Amazon deliver a charger, a couple of Wasabi batteries, and a car charger. All for significantly less than another (1) "factory" battery. Have Wasabi batteries for 4 different cameras, and never an issue.

Thank you all for your responses and telling of your experiences with Wasabi batteries.
MERRY CHRISTMAS to you all.

Wow, so many Positive, but also Negative experiences with this Wasabi Battery, I want to save money, although if I buy one or two and they fail, I have wasted my money that I could have spent toward a reliable name brand Nikon ENEL14a battery for my Nikon D3300. I could have a good experience as some have had, but then again I good get "Burned" with crappy off brand batteries. What to do, What to do,????

I am probably going to try a couple for my 6D and 7DII; but I noticed on the picture of these batteries, while it says "Premium Cells from Japan" on the main part of the label, in the lower right corner (in smaller print) it says "made in China."

CLP1943 Loc: Wisconsin

I think it probably means the cells inside the battery are manufactured in Japan and then
sent to China where they are wired together and put in the case. (Assembled in China)
Just my guess.

Basil Loc: New Mexico

That could be.

Way back in 1959 as a freshman in high school I got a Remington Travel Writer for Christmas (my teachers cheered, my writing was pretty hard to read).
It said "Assembled in USA", I wondered what that was about. Then I ran across an article about how Remington was a pioneer in outsourcing. The parts were made in the US and 5 or 6 other countries then assembled in their US typewriter* plant.

*remember those, mine is in the garage, somewhere, still works, ribbons almost impossible to find and I have had word processors since the early 90s.

This is the same thing, cells-the most important part-made in Japan*, case etc made in China and then assembled in China but due to language differences the label says "made in China".

Don't really care, they work.

*A few years ago I read that almost all of the battery cells in the major developed countries were made by 6 large companies, but there were many many brand names on the batteries. Probably a few more making cells now, but nowhere near the number of battery brands you can find.

Indeed I still have my Sears Graduate typewriter - but it's in bad need of cleaning and new ribbon.

I am going to order a couple of these Wasabi batteries. For $30 for two why not. I've seen enough decent reviews to take a chance.

I get mine from Amazon, and now the two packs can be had with a two battery charger for only $2 more than the batteries alone. Wasabi Power does say only charge on their brand chargers, not Canon, but their chargers will charge Canon. Two weeks ago I forgot and stuck two Wasabi batteries in my Canon chargers, they went dead very fast, seems the Canon chargers can't read when the Wasabi batteries are fully charged and think they are done charging when they are only partly charged. From now on I will just use the Wasabi chargers and put the Canons away as spares.

Basil Loc: New Mexico

I just ordered 2 with the battery charger and a car charger cord as well, for $29.99. As long as they report in camera and last at least close to the OEMs it will be worth it. We shall see.

I bought some Wasabi's for my Canon SX50. They are marked "Premium cells from Japan" but no fine print and no mention of China.
Where did you hear or read not to charge them in the Canon charger?

robertjerl Loc: Corona, California

Well, I just checked again and only one site says that, 6 other sites I checked said they are fully interchangeable. So, who knows, maybe it was just a mistake, maybe some of their older products were not interchangeable? And I can't find that site that said that, though I remember it said something about the chip in the battery not being read by the Canon charger.

Who knows, since the Wasabi charger holds two at a time and that is how I use them in my battery grip(s) I will just use the Wasabi unit, besides it is smaller and takes less space on the work table.

Got my pair of Wasabi batteries today, with a charger. Have not had a chance to try them yet, but one thing I did observe: When I put one of the batteries in the Wasabi charger, the light never turned green, even after what should have been more than enough time to fully charge. Put the batter in the camera and it registered 100% charge. Put it back in the charger for a while and again the light stayed red - never turned green indicating full charge. Put same battery in the Canon 6D charger and it flashed a couple time and went green. Conclusion: the charger that came with the batteries has issues. It does charge but doesn't indicate when it's done.
