Hi there,

Have the battery charged and get a load test done, this is the only true way to test the battery, also get your mechanic to do a current draw test to see if there is any current leakage that will be discharging the battery, often a faulty diode in the alternator will cause this, but the trick is the alternator will still charge as well, have this tested.
