Another Gen2 battery about to bite the dust

I would talk to Steve at autobeyours.com. He can probably help you or at least give you some options.

 

what are your future intentions with the car?

 

I'd choose #5

 

You could take the car to a dealer with concerns now. Likely nothing will be done, but you'll have a record of previous concerns if the battery dies just outside warranty. That might help out with a replacement then.

 

I vote for #5 then if the car can't sit, #4. The battery is not your problem until after the warranty has expired.

 

I'm not very technical.

But might it make sense (and would it be possible?) to deliberately accelerate the degradation of the battery so that it fails within the term of the warranty? And could you do this by running the car in EV mode to flatten the battery, and then parking and revving the engine to recharge, and doing this repeatedly?

Or would it not work? Or not be worth the effort?

 

Hi you could .. pull the pack out and let it rest for a week then after a week test each individual module voltage with a simple multi meter, this would give you a reasonable idea of which modules are different to the majority. Then buy a couple good modules off a reliable source on here like Brad or Jeff? shell out for a balance charger to go with it! would do it the world of good and you would own a balance charger to throw on the car annually

good luck

 

Go the dealer and report a problem, if battery is jumping up and down, then car is not performing normally (even if you are not looking at the battery level you can feel it). Report that the car feels sluggish, gets lower MPG.

If you have hills, just drive them a little bit more, so battery takes full charge and warms up.

I don't understand how option 5 would be a good choice? Because of self discharge? Then you would need to leave the car will battery at lowest level.

 

If it was mine and still under warranty, I'd take it to the dealer and explain this and try to demonstrate it. I would think that if they see that going on, they'd cover you. That's definitely a signal of impending doom. If they can't help right away, at least there's be a record for future use.

 

Keep in mind Toyota has been pretty good about warranty coverage if you are a little over, especially in CA. So if you were a little over 10-yrs, we'd be telling you to ask Toyota USA for goodwill warranty coverage, assuming the dealer did not immediately offer that if you are so close. I assume the first owner purchased/registered in a CARB state, that is the first requirement.

 

My 08 was like this when i first bought it and was like it for 12 months or more before I finally rebuilt a pack for it, after 12 months the pack still had not coded P0A80 it was just lazy! it is the first sign of a lazy pack however I don't think its going to fail as soon as you might like it to!

You will find it hard to deliberately sabotage the battery no matter what you do, prius protects its own.

Toyota wont even consider swapping out the pack until they actually see a big fat triangle on the dash and diagnostic code P0A80.

Best you can really do at this stage is start bugging Toyota and ask them to make notes on their system about it so when your warranty is up and the pack really dies, you can go back and say "I told you so" and hope for good-will due to it having been previously reported! .. I would actually keep going back once a month until they either A: get sick of you and put a pack in it or B: the pack actually fails

good luck

 

in that case, i would put a new battery in.

 

Yes there have been 2nd owner cases...we have no rhyme nor reason but it does seem those with lots of Toyotas or lots of service at Toyota do get extra consideration. Also I feel CA is good a thing..
