This is an incredible story. People often complain about the costly battery repairs on hybrids and EVs. Redditor Scoodidabop is quoted $4500 to replace the battery in a Toyota Camery Hybrid, as the car’s management system says the battery is failing.
Turns out a bunch of little copper connectors had corrosion. That corrosion was preventing the battery from operating normally. $20 worth of cleaning products later, his battery is functioning normally.
The frustrating aspect of this story is the notion that car manufacturers charge individuals to replace the entire battery pack, when individual cells sell for around $50. Let alone cases like this where there really wasn’t any need to pay almost $5000 to gut the car and replace the battery. It seems very wasteful considering how many rare elements go into producing EV battery packs.
