2005 pruis hv battery

Is this car out of warranty?

 

There probably is a code but maybe your reader cant access it?
What code reader do you have?

Also, did you thoroughly check all the other cells?
Perhaps there were more than just the one you replaced?

 

You need to get the mini VCI reader for doing battery related work on the Prius. Generic readers are of no use.

 

i thought ny had the 10 year/150k? could an 05 have been purchased before sept. o4?

 

I thought there was much more to it than just replacing 1 bad cell.....

Isnt a charge and re-balance of each cell in the whole pack pretty much a necessity when replacing bad cell(s)?

 

some are saying all the rebalancing isn't enough help to make the extra work worthwhile.

 

Since most people don't have the tools to do the job properly, and are only doing it halfway anyway.
Whatever replacement module you do get is not going to be exactly matched to the used ones you currently have.
So for DIY guys at home in their garage, you may as well just get the replacement module close enough to the same voltage,put it in and move on. The reality is you are going to have to go back in there again anyway since you aren't doing the fully regimen of the testing.

For example, commonly, most people don't have the tools to check internal resistance, tools to do load testing, or tools to check capacity.

 

i knew it was something like that, thanks eric!

 

Before you get in to opening batteries, check to see if your Hybrid system is under warranty. New York adopted California Emissions law, covering your hybrid components for 10 years/150k whichever comes first.

 

lew? king? king lew? hello?

 

Unfortunately this is what usually happens when people just put in new modules, balance and away you go.......turns into a game of whack-a-mole. Far better use of your time to buy the proper chargers, run both capacity and load tests on every module (including new ones), replace any bad modules, reposition all the modules to give you the most even load test average by block, balance the whole pack and you should have a battery that's good for a long time to come. It sounds like alot of work, but really it's not hard once you get the hang of it.

 

and here's another one...
