Great Panasonic battery. I've talked to Panasonic people and showed the the one I bought and they said it looks genuine to them. I put these batteries to test and they are really 3400mAh batteries. I 've attached a test result I got. I testec four of them in series and map out the capacity and cell voltages. I charged them to 4.2V per cell and discharged them down to 3V per cell. I got 3379mAh out of it. According to the datasheet of the cell, you will get 3400mAh when you discharge it down to 2.5V per cell so it makes sense.
It's hard finding good batteries that actually match their advertised ratings. I'm happy to say these batteries not only meet their stated capacity specs, but even exceed it! I just ordered 4 of these batteries and have tested them on my OPUS charger/analyzer (which I've used to test out numerous other batteries , and it always gives me accurate results). Out of the first 4 batteries I have purchased, the actual measured capacity w2as 3530, 3497, 3520, and 3498 mAh. ALL 4 exceed the advertised specs, which is very hard to find. I will be ordering more of these batteries. The only other high capacity batteries i could find on Amazon that comes close to this was the Orbitronics batteries, but they advertise 3500 mAh, and their actual capacity is a bit lower, around the 3450 to 3480 range, which is good, but not what they advertize, and they are also just a bit more expensive than these SunLabz batteries.... so this is the batteries i will be buying from now on. I use these for my...
I am a user of electronic vapor mods and ever since I got into this to quit smoking, I've been in search for the perfect batteries for my Sigelei LCD 150W mod. This mod doesn't have a power charging pass-through, so the batteries always have to be removed and docked in my Nitecore charger. First, I used MXJO batteries, but after using them for a mere week, the positive end started to flake and degrade. After a month or so, all four batteries were practically unusable, having no protection on the poles of the batteries. When I would change them out and swap, more often than not, sparks would fly out of my mod or charger due to uneven contact. After one almost started on fire, I got sick of it and bought the SunLabz 4-pack for my new go-to batteries.
These SunLabz fared much better than the MXJOs. Nonetheless, after a few months, the same thing started happening to them. Both the positive and negative poles began to chip away and deteriorate. My brother uses the same mod but...
