YFDF9 - 6-Cell Battery for Latitude 13 3340 3350

I ordered this as a replacement for my Dell Latitude 3340, which has an ancient YFDF9 that won't hold a charge. I received the 4-cell 43Wh 5MTD8 instead of the 6-cell 65Wh YFDF9 battery. They are interchangeable, but I had paid for the larger capacity. Happily, CPU medics has great customer service, so once I filled out an RMA request form on the website, I quickly heard back and they gave me a partial refund to cover the difference between the 6-cell battery I had ordered and the 4-cell battery I received. Hopefully the incorrect shipment was just a one-off error not reflective of what they'll send others, but it's good to know that their customer service will work things out if there is an error.
