Question: Do the batteries hold their charge? If you charge them fully but they sit in your bag for a few days are they still fully charged? Or do they drain?
Document: So you might expect that these batteries are going to last longer. You'd be wrong. The difference is that the Sony battery holds the charge when you are not using it. So you can take 20 shots. Wait a day and it's still the way you left it. These don't work that way. They drain at a pretty constant rate in the camera or out. So I charged them up to 100%. Then set them aside for a couple days and came back to completely dead batteries.
I have received this product last week. I charged them the first night I got it. I let the batteries sit for two days out of the camera. After day two I pop it in the camera and it showed 100%. I started using the battery. I took several videos and many photos (not continuously) in a period of 3 days. The battery still shows 62%. I have not used the second battery yet and I have not recharged it since the initial charge.
Of course, they were sealed up in a watertight bag... but each of them was exposed to the freezing temperature. in the morning when I popped in the sony battery, the camera read a charge of 20%. out of curiosity, I checked both wasabi battery's. they both still read 100%. This is really great to know if your the "outdoorsy" type. the wasabi batteries can hold up to a cold night.
I have a NEX 6. Charging time is not an issue since you get two batteries. One charges in about the time I drain the other, so no down time. I let one sit for two days, didn't drain at all and lasted about the same as a fresh one. Hopefully these will last for at least one year. Thankfully they are cheap.Charges fine in car or at home. Light turns green when ready.
I charged these up and didn't use them for 2-3 weeks, but when I did, they were still fully charged. They last every bit as long as the expensive original Sony battery at a fraction of the cost.
I contacted them to see if they would have the same issues I've experienced and they assured me that they had already gone through what I did and had found a manufacturer that could produce batteries that would work in my camera.I ordered from them but was still skeptical. The Batteries arrived two days before they were scheduled to and while charging the first, I popped the second one in my camera right away. These batteries, as reported, come 80% charged.
On the first day I got it I immediately charged and it placed one in the camera, waited 3 days to notice if it was still at 100%. And yes, I was surprised it was still at 100%. This was the case for at least one of the WASABI batteries though. I've yet to check the other spare.Charging the battery was a little confusing. Keep in mind that the charger itself has color indication for you to know when it's charging and when it's done.
They then operated normally and shot as expected for a fully charged battery. The other 4 batteries indicated charge just as the Sony batteries so a minor inconvenience. One charger was kept in our truck and the Sony charger was used in our lodgings when we had power. Very happy with these.
Great batteries. Hold about as many shots as a Sony brand battery, although the Sony battery holds it's charge longer. Left out of the charger these drain quicker when not in use. Charger is great and compact, and works well with their batteries or the Sony one I already had. Never used the car charger piece, but I'm sure it works as advertised too.
good good good came fast the battery are holding charge per the othere reviews iv read full charge yesterday still 100% today no drain off yet
Answer: Maybe some of their battery stock is better than others...mine held their charge just fine.  I am happy with my purchase.  I knew there had been some negative reviews when I made the purchase but figured it was worth the gamble at that price...it paid off for me.  Also, I figured the chargers were worth the price even without batteries so why not try.  BTW...the chargers work fine too.  The AC unit is way better than the charger that came with my RX 10.
