According to the ACPI spec, some kinds of primary battery can
report percentage battery remaining capacity directly to OS.
In this case, it reports the LastFullChargedCapacity == 100,
BatteryPresentRate = 0xFFFFFFFF, and BatteryRemaingCapacity a
percentage value, which actually means RemainingBatteryPercentage.
Now we found some battery follows this rule even if it's a rechargeable.

Handle these batteries correctly in ACPI battery driver
so that they won't break userspace.
