I recently got a new BE750G to replace my last one. They each have model number BE750G. Both units appear to have the same specs, but the first one I had was called Back-UPS ES 750 and this new one is called Back-UPS 750.
Here are some pictures showing the differences:
The ES 750 has white writing on it which makes it easier to read.
The ES 750 connected to the computer via an ethernet to USB cable.
The 750 connects to the computer via a USB Type A to Type B cable.
The back is the same except the writing on the ES 750 is brighter and easier to read.
