If your T99's battery is seriously drained and loses power after just a week of being parked, there are a few steps you could consider: 1. **Check for Parasitic Drain:** Ensure that no electrical components are drawing power when the car is off. This might include lights, the radio, or other electronics. 2. **Battery Health Check:** Have the battery tested to see if it's in good condition. Sometimes, a faulty or old battery may need replacing even if the car has only run 12,300 km. 3. **Alternator Check:** Make sure the alternator is charging the battery properly when the engine is running. 4. **Battery Maintenance:** If the car is parked for long periods, consider disconnecting the battery or using a trickle charger to maintain the charge. 5. **Professional Help:** If the issue persists, it might be a good idea to consult with a professional mechanic to diagnose and resolve the problem. Dealing with battery issues can be frustrating, but these steps might help in identifying and fixing the problem.
