I'm jsut confused as to how it neve rgave me a problem before , cold or hot, but just stpped working after the battery change? Is that possible?

NO......11.5 volts is NOT enough.....You should have 12.75 volts more or less on a fully charged battery (engine off).

12.68v . . . . . . . . . . 100%
12.45v . . . . . . . . . . 75%
12.24v . . . . . . . . . . 50%
12.06v . . . . . . . . . . 25%
11.89v . . . . . . . . . . 0%

Check your Alternator........measure voltage with engine running across battery posts......should get 14 - 15 volts more or less (if battery is not Dead).

Yes....that is possible you cannot start your engine after changing batteries if your charging system is not working or if you installed a Dead Battery.

Try another battery......just disconnect your Dead Battery and jumper a good battery with your Dead Battery disconnected. Do NOT try to jumper your Dead Battery.

Or.......you have an excessive battery drain with
Ignition switch off.

Check specific gravity of all cells of your suspect battery to make sure they are roughly equal. In your case no balls or maybe only one ball will be floating
