A very astute hybrid owner brought his 2007, 80,000 mile Toyota Camry Hybrid to our shop after seeing his check engine light. Computerized analysis of the hybrid battery pack found 2 severely compromised V-blocks in the pack. Replacement of the 2 V-blocks, followed by 2 power-cycling operations, resulted in this pristinely clean hybrid pack coming out factory-fresh. See for yourself in these before, during, and after graphs reflecting energy capacity of the pack. He picked up his Camry, ready for another 80,000 miles, and completed at a price thousands less than the dealer offers!
