Vin needed for new 2010 hybrid battery?

You'll only find a "new" pack from Toyota. You don't really know if they are new or "rebuilt".
Though some say they sell new blocks.
And they're expensive.

You should get the Sodium pack from Jack. It will cost less, and work better.

 

There's no difference in battery packs, but there's obviously something different in their system.

My guess is it would be the battery vent tubes because Toyota discontinued using the tubes on top of the pack in early 2010's because the hybrid cooling system provided more than enough ventilation for venting already.

So one vin# would be a pack with vent tubes and the other vin # would be one that didn't have tubes and it won't make any difference if you have them or not.

As a side note, it's a bummer that Toyota raised the prices so high on a battery pack recently . It was nice when all the Toyota Stealerships consistently sold them at $2K after you get your core deposit back.

On the bright side at least you found an install price that is reasonable. Of course if you lived near me I'd charge you 2 hours to do the install at $48 per hour.

More importantly, I agree with @ASRDogman you should consider having the mechanic install the newest most advance sodium-Ion packs which improves your car's overall performance in many different ways for a much lower price.

 

Around $1k

You could try getting a battery from amayama - I believe the site is legit and the price for a battery is pretty good.
