Did they "change" or "charge" the battery?

Allowing a car battery to fully discharge normally damages it behond repair.

If you have a multimeter, check that the charging voltage is 13.8 ~ 14.5 V with the engine running just to make sure it's charging right.

If you leave it standing for a few days again, try disconnecting the battery.
Before you disconnect the battery measure the voltage, then once its disconnected, and then again after a few days of being disconnected.
If the voltage rises immediatly after disconnecting it, then it would confirm some auxiliary circuit is drawing power with the car off (alarm, boot light, ....).
If after a few days (week) the battery voltage is still within 1 volt of when first disconnecting it then that's confirmation the battery is OK.

You could also take it to a trustworthy autolec and let them do a load check on the battery.
