SOH_CELL2_

BKUP,

0x02A4

These bits are the backup register for cell

2’s

SOH. This address is a R/W alias for the

SOH_CELL2 register.

The fuel gauge must be in learning backup mode

for this register to be written. For more details, see

the FG_BKUP_ENABLE register on page 33 and

the FG_BKUP_FLAG register on page 54.

Writing to this or any other of the cell SOH backup

registers prepares the fuel gauge to use the

values written in these registers as a starting point

for the SOH learning.
