BTY Batteries from Hong Kong sellers, BEWARE

I purchased some BTY AAA batteries from a seller in Hong Kong. The batteries state they are AAA, 1000 mAh. In reality, after charging and discharging many times, the best charge I could achieve is 150 mAh. This kind of energy gets you very little runtime in most electronics. You couldn't even run a LED light for more than a few hours.

Even the weight of the batteries is very obvious that these are inferior batteries. A Sanyo Eneloop AAA is 13g, while this is only 6g. Assume that the casing is 2g for the battery, which leaves only 4g of "battery" inside. The Eneloop has 11g of stuff for 850mAh, so it proportions out just about right why these hold so little charge.

Buyer beware, low price, big headache. Lesson learned.
