Expect to have some unexpected failures in the large lots of batteries.
Most of the batteries have met expectations. However, about 10% of them are faulty. They loose quality very quickly. Out of the package, most all show full charge, but a small, unexpected number do not hold up. Checking the batteries with a voltmeter, a fully charged battery will have approximately 1.6 volts, but so quickly some will drop below 0.9 volts and become useless. When used as part of a group in a device, the battery failures cause the device to fail. The failures cannot be predicted and are totally unexpected, and very disappointing. Not sure what is actually going on, but the overall quality control is definitely lacking. Compared similar batteries purchased in smaller packages, there have not been any failures, ever! So, if one can tolerate the failures these batteries may be a good deal. But if one can't tolerate the failures, one should find a more reliable battery.Read full review
