I ordered the product code AA-PB9NC6W from genuinebatteries.com for a genuine Samsung 5200 mAh battery and paid a premium price. They shipped a AA-PB9NC6B 4400mAh Samsung battery which has less power and is lower cost. After a number of attempts via email, phone and a PayPal protest to get this corrected and no response at all from Genuine Batteries, I had to get a refund via PayPal.
The battery was returned to a company called Blazin' Technology. A thank you card enclosed when I first received the battery was from Battery-Juice.com with an invalid phone number. This company may keep changing names after getting too many negative reviews. Caution is advised when dealing with this vendor.
