Q: Car is turning on (ie:display board). Not showing READY after pressing START button and pressing BRAKE PAD

asked by on September 07, 2016

Prius display screen is showing battery sign after pressing the START button. The car display board and computer sign appears but not showing READY sign with 0 miles/per to start the engine after pressing BRAKE PAD and waiting for the engine to start. Tried multiple times for 10 hours whole day over 4 days. And have tried jump starting the auxillary battery. Don't start car. Have changed the motor engine oil and put new filter. Still doesn't start car. The prius is said to have no starter or alternator built in it. I know it's the battery fault as the sign is showing it (I know there is two-1 is auxiliary in front and one traction hybrid battery in back seat). If the traction hybrid's one cell is defective after testing computerized (DO YOU HAVE THAT TECHNOLOGY WITH YOU TO DO IT?), can yourmechanic order and fix that only defective cell as the whole battery pack is very expensive like $5-3000. If so, the one or two cell is defective how much can we be looking into pricewise for it?
