Moving Battery Bank

[hohenwald48]

I am moving my solar battery bank.  (12) 6 VDC golf cart batteries paired for 12VDC.  Should I take care to reinstall the batteries in the same order they have been for the last three years or is there some advantage to reordering then when I reinstall?

   I'm a  believer in if  it an't broke don't fixit . I don't see how it would matter

you most certainly need to clean all connections  . So if they get jumbled so be it.

batteries should be rotated, annually is a good time particually the end ones. I don't know or have forgotten the reason.

The ones on the end of the bank have a different ambient temperature than the ones in the middle.  The ones on the outside will tend to overcharge a tad and the ones on the inside to never be quite fully charged.  Difference is small but might make a long term difference in battery life.

Rotating the outside ones in and the inside ones out would tend to equalize the wear.

But that's my guess.

I think it goes back to the days of lighting plants with end cell switches. To keep volts constant, the end cells were cut out as the batteries charged and during discharge they were brought back in as the volts dropped. As a result the end cells tended to be overcharged.

Don't think it would matter normally.
