Default Re: Battery Pack-Should I start shopping?

At 5-6 years old, it's probably time for a new pack. With those batteries being mixed they've probably been out of balance for quite some time and one or two are not charging at the same rate as the others. That usually leads to longer charge times as the OBC tries to maintain the last charge phase until the voltage stabilizes at a certain point to balance the pack. Eventually it's just not able to bring the pack into balance anymore.

Your voltage is close. The OBC has to get the pack above 58.3 I think is what Tahoedawg said. But checking the voltage of each battery while driving will show if any cells are significantly out of balance by showing lower voltage than the other batteries in the pack when under load.
