Check Di2 shifter battery level and replace it
12-speed wireless Di2 shifter batteries last about two years, and this page will teach you how to check the battery level and replace the battery itself.
Disc Brake Dual Control Lever (Wireless)
GRX ST-RX715
This ST-RX715-R is a cheaper version of the ST-RX827, meant to be used with 1x12 wireless Di2.
It comes in a right hand side version only, there is no left version. No left version with functional Di2 buttons, that is. There are brake only left hand versions of this shifter.
While it has GRX branding, it is actually more similar to the 12-speed 105 shift lever: ST-R7170. It has *no satellite shifter ports, no hood button, and two shift buttons.
Like the 105 Di2 shifters, these 1x12 GRX units take two CR1632 batteries. They should last for about 3.5 - 4 years.
