House bank is showing 14.5v charge at rest.  Last charge vis balmar regulated run for 3.5 hours.  I would expect batteries would settle after charging to 13.5v.  Batteries are Lifeline Series 31, installed in 2018 (6 years).  Any ideas what is going on?

Joesph,

 

How are the batteries being metered? Is this reading from a panel meter or from a multimeter on the batteries themselves? Are you certain there are no other charge sources?

Thanks Ben.  Reading is at panel voltmeter and the Voyager series 2000 inverter panel.  I will use multi-meter on individual batteries.
