I may need to replace the battery for my GL-Mifi. Where could I source replacement batteries? What are those connector pins? Is charging control on the battery itself? Or on the device?
It depends on which version you have. If your batter is 5 pins, the control is in the batter itself.
You have to buy from us I think. The battery is not a common one on the market.
You are suggested to write to customer service for these issues.
