Q: Hybrid car's battery cannot recover on repeated short trips

The battery in my hybrid car keeps going dead. This has occurred six times in one year. I took it to the Ford dealership, but they couldn’t find any problem. When the battery dies, I can not start the car and I either have to have it jump-started or towed. My car is used for just local short commutes and less than 3 miles. This problem is happening within those few three miles. After a week of that small amount of driving, the battery can not recover and then it depletes. I have read of other drivers with this hybrid model (plus all years of the C-Max model), having this same problem. I have learned that the battery capacity is not large enough to recover when driving repeated short trips. There are no warnings when my battery is low or when it fails. In your professional experience, is there a solution for this battery problem?
