Question on what dealership brand new oem hybrid batteries should look like.

2008 prius touring. 166,000.

recently triangle of death with just red car and exclamation point on display.

dealership said corrosion on 1 cell and need whole new battery. I should have pulled the codes but ignorantly dropped it off.

the car ran fine 56mpg no issues. the battery was charging fully green which i never really noticed it doing before.

my mom uses this dealership for her prius. when dropped off they were clearly informed to call me my number.

some reason they call moms number. she calls me and says that my car will be ready tomorrow. they put a new hybrid battery in it.

I was astonished. I pick it and ask for the codes can't remember what they gave no invoice on me. no P0A80A (failing hybrid).

I would have demanded to be present to at least see new battery. IMO they didn't touch the battery from what I understand a new oem battery includes the entire shell.

I still have the original old dull aluminum battery pack in the car. is this normal?


I have a few pics the inside was completely dusty. the pics are not good but hoping someone may be able to see something. there's a date year stamp on the black plastic piece of the pack kinda hard to read.

I've worked on cars for 39 yrs but hybrids I know zero.

can someone help.
