Huawei e5573 battery replacement

[wawinfo]

Hi friends. I have a Huawei e5573 4G router that works on battery like attached photo, unfortunately I can't find that battery and some how I want to use another brand like Samsung battery or maybe unbranded one, Can any one tell me about that two unknown pin on Huawei battery?
I know in some manufacturers there is a temperature ntc type sensor pin to tell the phone about temperature of battery while charging, and for that type I can emulate the ntc pin, but here are two extended pins, and I couldn't find any pinout and specifications about that, I will appreciate your help in advanced
