    This was an upgrade! Works great!

    My Auvio (Radio Shack) Bluetooth speaker would no longer take a charge. I searched for a replacement Lithium Ion battery that matched the shape and plug of the old one. A 3.7 volt 500mah flat pack. The picture on their website had an identically looking battery with the correct molex plug, but was 1000 mah. It looked about the same size. When it arrived it fit perfectly into the existing compartment of the speaker. Wow! I now have an improved model since 1000 mah will run twice as long.
    I am very happy with the product, the quick shipment, and the low price.

    Exactly what I needed

    My device was no longer manufactured. New, it cost me almost $400. The internal battery had died and this replacement matched the old battery specs exactly. After I installed the new battery pack, plugged it into the PC board, and put the device back together, it worked perfectly, for a tiny fraction of the device’s original cost.
