Prisu 2013 69k mile battery check hybrid system battery error P0A80 error

The first column shows block 7 is weak under load (shows 27 amp load). That is where the problem lies. A failing module in block 7 of the HV battery. A 27 amp load when driving isn't very much. Hard acceleration can show 150+

 

What is your level of mechanical and electrical ability?

 

What do you mean by replace a new battery? The 12 volt battery is not the issue. The big hybrid pack is the issue. Toyota is the only one that sells new packs. Some other companies repair old batteries with old parts and ty to pass them off as remanufactured, but they are just old batteries waiting to fail.

Block V07 is definitely low (12.32 volts). The next lowest is block V05 at 13.90 volts. If you are DIY and would rather repair, Hybrid Automotive sells used modules with a 1 year warranty. Their battery reconditioning system is highly recommended for balancing & reconditioning the battery pack. @jeff652 , the owners, is a trusted user here.

 

@TMR-JWAP is a good hobbyist who enjoys carefully testing & rebuilding battery packs.
Companies selling the packs do not take the time & care needed to rebalance & test them so they tend to fail.

 

I met a guy (Hi Pete!!) who was in a similar situation. He drove with a scanner attached to the car OBD port to enable him to reset the fault immediately. Not recommended for long term, but it could get you by for a bit, most likely. If you are DIY, brush up a bit by reviewing some videos and reading some of the postings here about module swaps. You can be successful in a DIY module swap and have it last years if you're a bit lucky.

 

The battery reconditioning system I mentioned in post 6 consists of a grid charger & a discharger. The system charges the pack above the normal range & discharges below the normal range to help balance the modules and extend their life.Usually, once a module throws a code t needs to be replaced first anyway.

Some people take their chances , buy a used module from ebay and hope for the best. That is not recommended if you need a dependable car.

 

Hybrid Automotive has started selling professional systems to garages that recondition quicker.
If the local place is using one of those systems, that may be a reasonable option. Hybrid Automotive should be able to tell you if that local place is one of their customers.

If they are not using that system it is probably a better option to do it yourself with the Prolong system.

 

Howdy Brad. Bummer and sorry to hear. Been there, done that and didn't get the shirt. Not fun.

There is a really great vid some one posted and I'll find it and post.

Just remember, it is going to be OK. It really will.

I'll look for that vid first thing when I get home.

Really amazing and demystifies the big, bad battery .

Als the video offers other things/possibilities

Wish I had seen it be fore my batt. died on last Pri.

 

I believe Hybrid Automotive charges $50 and has a 1 year warranty on their module. Without balancing & reconditioning the chance is greater for another code. That code is set when the voltage difference between modules is too great. I would guess a module in V05 might be next.
I thought there was freeze frame codes that isolated which module in a block is bad though. A block is composed of 2 modules.

 

Do I really need to do the reconditioning of the entire battery pack?

Brad, Look through this thread

and read post 28.

It all depends on your resources and the time you have available.

 

Are you sure you meant 18? That is when you grabbed a used module off the shelf.
