Battery life estimation

Measured scenarios differ depending on protocol. This section shows the most common data exchange patterns and their impact on battery life.

Two lithium batteries were used for testing, as shown in the following table.
Table 1. Battery information
Battery name Attribute Value
CR123A Standard capacity 1550 mAh
Yearly loss 2%
15 year self-discharge loss 465 mAh
Effective battery capacity 1085 mAh
Effective battery charge 3906 C
CR2032 Standard capacity 235 mAh
Yearly loss 2%
3 year self-discharge loss 14.1 mAh
Effective battery capacity 220.9 mAh
Effective battery charge 795.24 C
A CR2032 battery is often used in small, size constrained devices. For testing purposes, the PCA10056 Development Kit comes with a CR2032 battery holder, so the board can be powered directly by the battery. For larger devices, the CR123A battery is used for device lifetime estimation.
