I checked all the wiring and connections in my car, changed the alternator, and changed the corroded battery terminals. I start the car, and im still getting 10 volts! I then decided to buy a 16 volt racing battery which will hopefully get the juice I need to start the car....problem is, will the car be able to take that much voltage without doing any damage?

hmmmmm i foresee damage

you have a problem with your wiring sir, a 16 volt battery is no the way to fix your problem, but it could make things worse for ya.. besides you would need a 16 volt alternator to charge the 16 volt battery, not to mention the 16 volt battery chargers are another $300.00

16 volts is exceeding the maximum voltage into the ECU and will result in light bulbs and electronics burning out.

What is the 12 volt battery reading??? Sure you just don't have a bad battery???

16V battery? What is the application for that?

Get the battery checked. Bring it to your local auto store and they should be able to tell you if its good or not.

What are you checking the volts with?

very very bad idea

do a ground check, corroded battery terminals is only the beginning. Check to see if the wirings going to the alternator is not corrodded as with all the other harness grounds

16 volt batterys are used in car audio

what was your bright idea for trying this one out?

lol, i have never heard of anyone trying to fix a charging issue by installing a larger battery, that is backwards thinking..

I hope you haven't bought it yet because this is a very bad idea. If you can't get ~12V from the battery with the engine off and 14V+ with it running then something it broken and needs to be fixed. You don't need a higher voltage battery; it will cause damage.

How are you measuring this voltage? If you're using the stock gauge please use a proper voltmeter on the battery itself before posting again.
