The regaining of battery capacity from 50% to 83% (2007 Prius) through the use of Hybrid Automotive's Prolong balancing kit.
The rebalancing/reconditioning of all 28 modules can also help get rid of the RED triangle of death indicated by codes P3018, P3006,P0A80,and P3017.
There are a lot of ways to rebalance hybrid battery packs but after a little research I found the prolong system to be the easiest and most foolproof.
