Starter Battery or Charging Problem

[Kyle Ewing]

I have a 6 year old Optima group 34 starter Barry charged through an Echo Charge.  Due to a wiring problem from the echo charge it wasn't charging late last year and was left at about 50 percent charge over the winter.

This year battery voltage at rest is 12.5.  Turning the key drops it to 11.9. Battery voltage while engine is running and charging through Echo Charge is 12.2 volts.  I remember 13 volts from last year.  Voltage from the Echo Charge when not connected to start battery is 14.1.

The engine still turns over and starts as it should.  Any reason not to believe the battery is on its last leg?  Next step is to remove the battery and have it load tested.

The ample power primer, I think it is in the wiki has a method for restoring batteries that have been discharged.  Might want to try that, but I think you battery is pretty close to a dead.
