Toyota Aqua HV & check engine light code

AOA all members
Hopefully, you are all fine and doing well. I am facing an issue with my Toyota Aqua S package Key Start. Some lights like check engine light, slip warning light, EBD light & Hybrid System Abnormal light popped up on the meter when I was driving the car. Then I went to a local electrician, he checked by connected the board and error code P0a80. As I have driven the car over 1 lac kms and I decided to clear the codes. After that no code appeared whole day. I was driving the car next day and left home, the same issue appeared again. I went to electrician again and asked him to clear, he cleared on my order and asked me to change the hybrid battery in the car otherwise there is no other solution. Then I visited another electrician he asked me to clean the motor which is I think located under the back seat. I did some research on the internet and found that this code may appear due to a bad cooling fan so due to which the battery could be overheating. However, I checked the fan which was clean. I am attaching the pictures here for you. Kindly help me to find out that what is the actual issue? And how can I resolve it? I will be very thankful to you and will appreciate your guidance and opinions. Thanks in advance.

In some cases Terminals of each of the cells of the battery pack get corroded and the proper current does not flow. It happens in some cases. Because of this warning appears to change the battery. Thes batteries have a kill switch you need to remove it and then you will be good to go and you can work on it.Use vinegar if cells are not weak clean the terminals.
