Well, here's what I did this year: (the other one is done at the end of June) Biannual Full Recondition of Traction Battery: Date 20171226: Prius Hybrid Traction Battery long recondition 128,500 miles Chrg1: 31 hours 248V 356mA Dschrg to 134 V - 6:45 hours Chrg2: 32 hours 247V 356mA Dschrg to 84 V - 6:45 hours ("dead-cat-bounce" had taken the V back up to 190V when I checked!) Chrg3: 33½ hours 249V 356mA Dschrg to 17V ~ 7 hours (I started checking around 6:45, and the meter was at 60V, and dropped at 10V every 6 mins or so, and I was able to hit the 17V on the nail) Chrg4: 40½ hours 250V 354mA (…yippee!) now leave for 2 hrs to recover! Total elapsed time - 159½ hours (6½ days) Last year I did it over the first week of the New Year. (…there, I bet you're glad you asked! )
fortunately, we had enough alcohol on hand that i was able to survive my relatives. i am thinking of a volunteer mission next year.
Only for grumpy old men. Apparently they can't get enough of them, so if you think you could qualify....
