I have a 2004 Prius. The battery had at least one bad cell so I "reconditioned" the battery. That is, I took all the cells out and discharged and charged each one 3 times. 2 amps to drain and 2 amps to charge. I replaced three cells. It took a month. Now the battery is back in the car. The car runs fine. But the battery charge indicator of the car shows the battery charge at 80% and up to 100% all the time, Never less than 80%. How do I make the car let the battery discharge down to 40%?
