Is this consistent or does it vary from boot to boot or if you
disconnect and reconnect the battery?

But is also over 3 years old.  Almost everything you do to LiION
batteries makes their capacity drop.  Whilst 279mAh is probably
a bit unrealistic, I wouldn't be at all surprised if the real
capacity was 2790mAh.  (Having ACPI values be out by exactly an
order of magnitude seems fairly common - I've yet to see a system
where at least one value wasn't reported as 10x or 0.1x the
actual value).

These numbers seem realistic.  Your best bet is to see how long the
system lasts on battery.  (If you regularly run on battery, you should
probably install some monitoring tools such as sysutils/battmond and
sysutils/xbattbar).
