Default Advantages to a 14v battery and alternator over the 12v and alternator

I ordered a xs power 14v battery without realizing i have a brand new 12v laying the the garage. Pretty much looking for an answer to if i should keep the 14v and run it. Is there alot of advantages to it? I know you might get some more out of your fuel pump and water pump and fans but anything else?

More voltage going to the starter with a 14v battery, After it's running it make no difference because the alternator is putting out 14v anyway.

but with the alt itll pull around 16.5-8 so itll be a 16v system. Any benefit to that?

No, there's a voltage regulator in the alternator so it won't output 16V unless it's defective, regardless of the battery connected to it.

^^ That. I didn’t know they had a 14v battery. I like the concept.

on a 12v alt yeah, but they have alts that are 16v such as the powermaster 8018 xs volt

^ But you didn't mention having a 16v alternator, so WhiteBird00 and LLLosingit were absolutely correct.

The 14v battery would probably be a nice thing in a super cold climate, and/or for use with very high compression engines. I assume they might have a longer service life in an application that was designed for 12v, as the age-related resting voltage drop of the battery would show less of an impact in the early stages.

What "type" of battery is this (i.e. composition)? How does the price compare to 12v? I've never heard of these either. I could also see it being useful for an application like my Nova where the electric fan tends to run for a while after the engine is shut down.

sorry should have mentioned it being a 16v alt in the title. heres a link to the one i bought. https://www.jegs.com/i/XS-Power/703/D1400/10002/-1

Then if you have electric fans, electric water pumps, electric fuel pumps etc the added power will help. As long as things are rated at running the higher voltages.

It will only help if they are undersized, If they are up to the job at 12volts then there is no benefit of running them at a higher voltage. The only reason I could see someone wanting to run higher voltage would be to put the more power to the starter and into the coils/ignition system.

i can see that and i have a fuel system that wont be a problem at the lowest voltage. im thimking i might save my money and run the 12 v with the alt
