Quick question??

who makes a 14 volt battery?

 

Where will you get 14 vollt bulbs, wipers, fans, radios? What would charge a 14 volt battery if you found one?

What are you hoping to solve with 14 volts?

 

13 volt angst?

 

Perhaps two extra volts are better than one?

 

Don't really know why, but here it is.

14 volt AGM Battery.

 

I wonder if it's really 14V or just a regular 12V battery with more attractive labeling....like the Spinal Tap amp that goes to 11.

 

XP1000CK1 - XS Power they seem to be sold with a A/C charger because nothing in the car can charge them.

 

^^This is why it's a bad idea. I assume they've added a 7th cell. If that's the case, the car can't keep it fully charged. Lead acid batteries are happiest fully charged. You'll be running around with it at ~85% charge shortening its life. It will actually be flat at ~12V.

Bad idea all around. Throw the absurd cost on top of it, and it drops into the toilet, IMHO.

 

I never said it was a good idea or practical. I simply pointed out there is such a animal. Vendor also claims to have a 16 volt battery. Supposedly these high power batteries are for vehicles that are sporting large amps for sound systems and so forth.

I do agree that most on board charging systems will not charge the battery fully which will cause a short life span in the Prius.

 

The charging converter on my gen 1 only puts out 13.6-13.7 volts. Most alternator driven charging systems max out at about 14.5. A 12v battery is 13.2v at a full charge, 6 cells @ 2.2v each. I imagine your 14 battery is fully charged at 15.4 volts.
