94 lincoln town car wont start

I have a 94 lincoln towncar it seems like it would be the battery so i put a charger on it and the charger reads 0 and all it does wgen i try to turn on is clicks and all the dash lights go out. I am at a loss please help.

How old is the battery? A worn out battery can't simply be charged into working again.

You need a voltmeter on the battery static. Just because it shows 12v static means it is any good. Voltmeter on the battery when trying to start. Drops below 9-10, battery is toast. Most auto parts stores will do a free battery load test, alternator etc.
