Please my hyundai santa fe 2004 model developed a fault recently,each time the car is parked,i always need another battery to start it,it weakens/drain d battery each time.please what might be happening or be the cause?
It is a 2004 Santa Fe, how old is the battery? If it is the original battery it is more than likely shot/worn out. After 5 or 6 years most batteries are near the end of their life cycle.
If fairly new you may have an open circuit in the system. When the key is off there is something still taking power from the battery. When the battery is fully charged, disconnect one of the cables, or both, over night. Reconnect in the morning ans see if it starts.
There may be a bad cell in the battery.
Best bet is to take your Santa Fe to a dealer or auto repair shop and have the battery and system checked out.
