Usually the battery itself is covered for a year, however the usual AppleCare extended
plan runs for three years including the first year of complimentary service coverage if
bought within the time-frame, as the extended plan adds to total includes and original.
Were you able to contact an Apple authorized service and/or sales provider in Vietnam?

About batteries and power:

The computer should have a diagnostic performed to see if all that is acting up, is the
battery; since they do age and depending on use situations and conditions, like air
temperature and how the computer is used, if it were ever let run completely flat, so
the battery would sustain damages if let run until empty of power; these can all make
for a shorter than ideal battery life. Even using the screen on bright, can deplete the
ability for the battery to fully recharge over a possibly longer life span, over years...
Battery cycles and voltage capacities, storage abilities, are impacted by actual use.
You could ask the authorized Apple service provider if they could replace the battery
under the extended AppleCare plan before the time runs out. They may, however I
am not a party to any determination they may make, as a participant in a peer user
to user help discussions section, and not representative of Apple, Inc. or its policies.
According to the serial number you posted (usually is not allowed & gets deleted by
the Hosts) I used this lookup https://www.powerbookmedic.com/identify-mac-serial.php
the resulting information came up from the site:
or see Apple Support article to confirm build model details
How to identify your MacBook Air - Apple Support
If you are asked to purchase the replacement battery instead, as may be the case if
the company performing the service does not see the part as one covered under the
AppleCare plan, the part may in cost (citing in USD $) as much as $160. or so. They
may or may not be able to replace the battery for free under AppleCare. I can't say.
They may (or not) perform the labor for free, if you have to buy their battery, if the unit
(replacement battery) is not covered by AppleCare.
Or you could see about buying a quality replacement battery and install it yourself...

Sorry to not be able to answer about how Apple Care may be interpreted in your locality;
however you should contact the Apple authorized local entity for service and ask them
because the battery may be seen as a consumable, and perhaps not expected to last
more than one year. This would not be unexpected, if they were to suggest a short limit.
You may be able to see about setting an appointment or contact one of the Vietnam
Apple authorized service affiliated businesses, if not in the city (search I used) indicates
choose a different city name in the Locator, under Service. You may also check to see
if the Sales locator search brings up additional ones. The Map has click on to get info.
Two cities' service result links, from Country search appear above. That may help...
You should be able to contact the company nearest you if they do not appear in the
Apple Locator by city name and ask the question of their service people, if they do
repair replacement under AppleCare.
In any event, sorry about the inconvenience.
Good luck & happy computing! 🙂
