Figure 18: Battery current versus time
Powered by the system
If power to the board is supplied by the system then the battery is not supplying
power to the clock circuits. However, self-discharge happens. Typical self-
discharge rates are less than 0.3 percent per year with respect to a fully loaded
battery at an ambient temperature of 25 °C. Self-discharge rates increase by less
than 3 percent per year for temperature values up to 95 °C.
The battery has a user accessible holder on the VR11.
