    Q:

    I only got 3 working batteries after paying the seller for 4 batteries. How can I contact them?

    A:

    You can contact us through email or the service email on the back of the box, we will send you the replacement for free.

    Q:

    What is the weight of a single AA in grams?

    A:

    I can tell you that the AA Li-Ion version is 17 grams, NiCd AA is 24 and AAA is 12.

    Q:

    How long does the charge last while not in use?

    A:

    It has a high retention at mid-charge, and will die out within 2 weeks if it drops under 20%.

    Q:

    I'm afraid the batteries will catch fire if they reach temperatures over 140 degrees.

    A:

    It is too hot and should not be used. Even though it is not a safety valve, it is a fuse that can break and can't be reset, but you should be protected against a fire like the seller pointed out.

    Q:

    Does the port only charge the battery or can you charge things from theusb as well?

    A:

    The 4 in 1 usb cord is very short, but it works.
