Bests & Worsts Reviews from Amazon

These batteries like many Chinese batteries are not the capacity that they claim. I have used them for a while, and they didn't seem to work quite as well as I had expected. I finally put them in my Opus battery analyzer. First, I ran a refresh pattern on them. This charges them all the way up, then all the way down, three times to get the batteries into top condition. Then I charged them fully and ran a capacity test on them. I did this with multiple samples, and they always were between 4,000mAh, and 6,000mAh. I have attached a picture of one of the typical test runs. Update - 11/27/2016 EBL support is very responsive, and had concern that I was unhappy with the product. They sent me 6 more batteries. I chose two batteries out of the package and loaded them into the Opus analyzer. After running a refresh pattern which fully charges and discharges the batteries 3 times to get them broken in and into optimal condition, sadly they performed even worse than the first sample. They were 2743, and 4113mAh. While EBL has great support, they like many foreign manufacturers they appear to blatantly lie about their capacity. Additionally the previous test that I ran on that analyzer was some Ray-o-vac AA batteries, which performed within 10% of expected. This proves that the analyzer is working correctly. For those geeks out there, I ran the test at 500mA (20h rate if the batteries were really 10,000mAh as specified) on an Opus BT-C3100 with software ver 2.1 You can read about the analyzer here: [...]
