13.4 Volts Normal Battery Voltage ????

[David Carrol]

Plugged in full hook ups what should your house battery voltage be?

My battery was a little warm and read 13.4

Thanks for your comments.

You may need to check the battery fluids... Staying on 13.4-13.6 VDC for long periods of time may boil out your battery fluids and the batteries will then start getting warm to hot just before they die...

David,

If you have AGM's, 13.4 is the float voltage for Lifelines and you're right on target. Same would apply to wet batteries, the voltage settings are close.

Tom is correct, it all seems normal for the most part.
