2.3 Installing and replacing batteries
Your powermeter uses common CR2032 coin cell lithium ion batteries. If the battery
reaches 0% on one side, the other side of the dual system will automatically operate
as a single-sided powermeter; reported wattage from this side will be doubled.
When the reported battery life is 8%, you will have 8-10 hours of remaining usage.
Non-drive-side crank arm replacement instructions are in Section 2.3.1
Drive-side Dura-Ace FC-9000 replacement instructions are in Section 2.3.2
Drive-side FC-Mxxxx (XT/XTR series) replacement instructions are in Section 2.3.3
Quick Tip: When storing your batteries, keep them separated; shorting a battery
will shorten its life.
