Can I tel lithe age of a battery?

@TMR-JWAP You are one of the battery experts.

 

Never seen an OEM painted case. Look closely at the stickers, they've been masked for painting with some red overspray (there's your sign).

The absolute best way to determine age is to remove the cover and review the date codes on the modules. I'd wager that one is a rebuilt and has modules from several different years.

GOOD LUCK!

 

I think the Toyota serial number decodes as 24 August 2006 according to this post.

The 'advance search' feature still works for some reason

If this was installed by Toyota, there would be associated service history. Ask for the VIN and look it up at http://toyota.com/owners
You could also take the VIN to a dealer (or over the phone), and they should tell you if the HV battery was replaced and when.

If the service is listed at Toyota, then remove the cover from the battery case to confirm that the module serial #s match one another.

2x on what @fotomoto said, never seen a painted case from a dealer.

 

It does mean you should not trust the battery.

 

By the way, they lied.
Toyota only installs NEW battery packs.

 

I've completed enough orbits around the sun to finally get it thru my hard head that the answer to nearly all questions about human behavior is....... money.

 

There was a brief moment in time where Toyota offered and installed refurbished packs, but it didn't last long.

 

Is that one of those kidney bean batt jobs?

 

I understood it was only a small number of dealers in California.

 

You could take it to Toyota and ask them but the serial number would usually tell you

 

@Prodigyplace is 100% correct. The manufacture date of the CASE is 8/24/2006. That doesn't mean the modules are the same. You would need the serial numbers from the tops of a few modules.

On a module:

1. the first 2 digits are the day of the month
2. the next digit is the month (1-9, x, y, z)
3. the next digit is the year, with L being 2010. (M=2011, etc)

On a CASE, with that style sticker:

1. the first digit is always a letter code designating what vehicle the battery is intended for. (prius, camry, etc)
2. the next 2 digits are the day of the month
3. the next digit is the month (same as #2 above)
4. the next digit is the year, with L being 2008.

 

Any idea who paints the pack red? I know you have accepted several bad rebuilt packs after people gave up on them.

 

Red is a bit funny for me. Over the weekend, I was shopping for some parts for my sand blaster, because I have several gen 2 cases I'd like to blast and paint. Nice condition cases are getting hard to find, as most cores seem to always have those large corrosion stains. I had looked around at colors other places were using, and even did a google search to see what color was most associated with Toyota (like Blue is a Ford thing). Guess what came up as "Toyotas color? Red. Since I also didn't see any other rebuilders using red, I thought I'd use it. Not anymore. Sigh..........back to the search...
