Re: wise or unwise: replace 1 of 4 batteries in house bank?
One "trick" the technician at the shop instructed me on was to change the order of the batteries in the bank every 6 months so that the first battery (that closest to and attached to the charging source output) becomes that last (furthest from the charging source) and each battery in the bank moves up one position. Rather a lot of work but if it preserves the batteries better, rather worth the effort I suspect.
With a properly wired battery bank this isn't necessary. Properly wired the negative is from one end of the bank and the positive from the other. This draws across the bank evenly as shown below.
