Hi,

My refurbishment experiments suggests the health and status of the modules has a lot to do with NiMH battery efficiency:

It is enough that after replacing a traction battery pack, there is a period of 3-4 months where the MPG shows about a +2-4 MPG over the following, years of performance. I saw this first in the Dept. of Energy Prius fleet studies and later in Patrick Wong's data.
