Hybrid Battery Error

Any chance your 2013 with 53k is still under warranty? Especially for the hybrid portions?

 

you need to test the battery under load.

 

This code is set when the HV ECU sees a difference in voltage between modules. Typical agreed upon threshold for setting the code is a difference of 1.2v between the highest and lowest module.

When there is no current, the blocks will all be the same value. However, when there is current, different resistance between modules/blocks/cells will cause different voltage readings. If the disparity is too great, it'll set a code. This is where the corrosion problem comes in... Corrosion on the terminals can be a source of resistance, and cause one or more blocks have different voltage readings under load.

However, in the vast majority of cases, it's not terminal corrosion, but resistance in the modules themselves, that causes the problem. If you've cleaned the terminals and still have the problem, you need a new battery.

Aftermarket and reman batteries are always a bad choice. Low mileage used batteries are sometimes a good choice. Depending on where you are, Toyota has a rebate on the old battery that cuts a huge portion out of the cost of replacement. Here in Japan, it's about $1,500 for a new battery on a C (Aqua) including installation at the dealer. In hot and humid locations, we see batteries go bad in your age/mileage range, so it's not uncommon, but you should talk to Toyota about replacing it under warranty.

Here's a really good article on P0A80, and actually "testing" the battery: Art's Automotive

 

if the battery measures within parameters under a correct load test, your problem lies elsewhere.

 

Sorry to say that your information is not correct.
Used batteries and individual cells are commonly available. Pls share your location (city) I will give you contacts who can help you solve this issue.

 

Can you please guide me for Islamabad, whom to contact for diagnosis and changing the cell of hybrid battery.

 

Hello there
I am also having trouble with the batter, did you by any chance happen to import a battery please help me out here.

 

Hello Mohsin, I am in Islamabad, can you please guide me who can help me?
