The guy that I use to rebuild my batteries has recently commented that most of the bad cells he has replaced have been on the driver's side of the battery farther away from the cooling fan. He has since started rotating the cells as preventive maintenance as part of the rebuilding process.

I am interested in other peoples experience regarding where they are finding the defective cell/cells.

Based on threads I see here most are in the middle which makes sense heat wise.

My one failed module was near the driver's side of the battery, but it was not a heat issue (I live in CT and my Prius seldom sees high temperatures). I had a single cell reversal due to imbalance and the rest of the modules were in good shape after rebalancing.
