Not necessarily. Any battery, even a good one, will slowly loose it's charge. Could be that something drained the battery. Clean the battery case and the posts. Slow charge the battery until it is full and then use it. You will soon know if it is good or not.
There could be a bad sylanoid or a bad starter...

This may be a sign that your battery needs to be replaced. However, there may be other causes as well.
Needs a battery, most likely. Have the alternator checked after replacing the battery. Additional Info: It could also be a loose battery connection - check the battery cable clamps. Also, if the battery needs to be replaced, lock and unlock your doors with the key as the alarm system activates itself when a battery is removed, disconnected or replaced. Cycling the door lock cylinders resets the alarm.
If you have just replaced this starter then you probably have it hooked up incorrectly. If it is still the same old starter, then it has shorted out inside and needs to be replaced.
the bronco needs to have the ground wire connected from the battery to the body. if you replaced the battery and disconnected that ground it simply won't start.
