2013 Prius Plug-In Replacement Battery Cost

They're generally not failing, so you may find it hard to find someone who has paid for a new replacement traction battery. Some have been replaced with used batteries.

 

I've only ever seen one report here of a PiP traction battery failing. And there was a second hand account of one failing.

In the infinitesimal chance that your battery fails in the next couple years you'd probably need to either find one in a salvage year or just replace the car. But keep in mind, if you were in a CARB state, that battery would still have two years left on its warranty. And most last WAY beyond that.

One caution though. I don't know if you have lived long on an island, but if you've been there a while, you know about what the salty air does. I'd open up the battery case and check for corroded wires and connectors. That's the most likely failure point when you're on an island. Rust is any car's worst enemy in that environment.

 

i would either resign myself to driving it until the battery fails, then dumping it, or not going with a plug in.
personally, i don't think it will fail, odds are very low.

 

I echo what the others are saying. It will most likely just keep slowly losing capacity, but I doubt it will fail anytime soon. Lithium is a stable chemistry

When I bought my 2014 plug in last year I thought I should have a back up battery because if you need one it seems like you have to pay a lot more for it. I got a 2015 with 67K miles for $625 delivered to my door. It has all 4 sections. Before that I got one section for $220.

 

It seems like a waste to bother getting a spare traction battery - Li-ion batteries have a shelf life so it will degrade regardless if it's used or not, and if it's not maintained in some way it will degrade even faster (e.g. if voltage gets too low).

 

Yeah same thought here. It's good to know there are options, but don't dive in and get a spare; just educate yourself as to how/where they can be obtained, and recheck periodically, that sources aren't drying up or whatever.

 

how can all this be cheaper or easier than buying a corolla or some such
