In that case it should be indeed POWER_SUPPLY_PROP_CHARGE_FULL,
which is full_active_uAh, which we get from di->raw[DS2760_ACTIVE_FULL]
and di->raw[DS2760_ACTIVE_FULL + 1].

We fall back to deriving it from rated_capacity if full_active
is 0 (your case?):

        /* If the full_active_uAh value is not given, fall back to the rated
         * capacity. This is likely to happen when chips are not part of the
         * battery pack and is therefore not bootstrapped. */
        if (di->full_active_uAh == 0)
                di->full_active_uAh = di->rated_capacity / 1000L;

So, you probably want to make DS2760_ACTIVE_FULL writable, not
DS2760_RATED_CAPACITY.
