07-17-2012- Other Thoughts: Build quality is good -built-in circuit to prevent overcharge -near 4000mAh. <br/>The foil that holds together the battery and the circuit can be damaged at the edges. This haven't casued any problems yet, the battery is still in one piece, so it's seeming to be an aestethic problem only

06-02-2012- Other Thoughts: Very long lasting. They fit my flashlights very well. Protection card at bottom of cell works very well keeps from over charging and low voltage from ruining the cell. Great product well constructed. <br/>So far, they are just great, work very well. Best ones for the money that I have found so far.

05-23-2012- Other Thoughts: So far no recharging issues, they holds charge for a long period, no degradation in performance after approximately 15 drain/charge cycles. <br/>The ones that i received were manufactured slightly longer than standard size, they required a significant amount of force to put them into the charger

05-15-2012- Other Thoughts: It works in the first few months, and it has a huge amount of mAh. <br/>After a few months the battery just stops charging. I tried several different charges - both batteries stopped working after 6-8 months.

04-30-2012- Other Thoughts: Actually I have charged my batteries with this just once, but batteries are still in use, so this has charged them very well. Price is good and I selected this one because of other user report about two independent charging slots. Great. <br/>Plastic, but with this price that can be accepted

04-19-2012- Other Thoughts: Good capacity <br/>Almost no self discharge <br/>Protection circuit works as expected. <br/>it says 3.7V but my batteris outputs 4.16V, so it maybe can be harmful for certain lasers and other devices...

03-21-2012- Other Thoughts: I ordered this battery from them and we had a slight problem with delivery. They VERY responsive and corrected the problem VERY fast even though the product was a cheap item! I would use them again and recommend them to friends.
