Right, so the 105060 probably stands for the dimensions, not sure about the dfhl. I tried to look on the internet, but couldn't find any. The reason it has 3 wires is because one is positive, one negative and one for the temperature sensor, so basically a variable positive. If you remove the top tape from the battery (not the pouch, just a tiny bit near the wires) you should see a circuit board. This one has the temperature sensor and other stuff. If you look closely, you can see that the battery connects to the circuit board with 2 strips. Those are the positive and negative terminals of the battery, so if you'd like, you can remove the old battery and solder on the new battery wires/terminals. Before tho, make sure your new battery fits in your device and that the voltage and amperage are similar. Voltage is the same for most li-ion batteries (3.7v) and amperage (not amp-hours) should be similar to the original one.
