when you buy a 2013 or 2014 do they put in a new battery ?

 

No, not unless the currently installed battery is failing, which would be unlikely on a 2-3 year old car.

 

We probably CPO 20+ RXs a month, it's uncommon for a battery in a 13 or 14 to fail the test, perhaps 1 in 8 or 10 fails.

 

Part of the CPO process involves doing what's known as a load test on the battery using a battery tester, I seem to recall that its called a GR8. I know that the techs attach a copy to the CPO checklist.

If memory serves, the battery has to be around 70% of capacity to pass CPO standards; most of the time when a battery "fails" the car starts up just fine.

Like most anything consumable on a CPO the standards for replacement are much higher than what you or I would do on our own cars.

Edited to add: If you want actual specifics I can find out tomorrow.

 

For what its worth, I bought a 2013 RX-350 CPO in February with 22K miles, and they replaced the vehicle battery during the CPO inspection. No idea why. While looking on line before the purchase, I saw several other RX's that had their battery replaced and thought that was odd.

 

They will do a load test and only if it fails will they replace the battery.

A lot depends on geographic location and temperature. Heat will accelerate battery degradation.

I traded in a 2012 CT200h and a 2014 Ford F-150 Lariat last year to the local Florida Lexus dealer. Neither car had any indication when I owned them that there was a battery issue yet the dealer replaced the 12 volt battery on both before putting it on their used car lot.

 

I purchased a 2013 CPO RX350 in February. According to the service records they did a load test, and replaced the battery as part of the CPO process on 1/22/16 and 284xx miles

 

A battery costs $120 tops. But perception is worth a lot more. When buying a CPO, you feel like buying almost brand new. Return on Investment. You know that pissed customer will never be happy again, when one morning the engine would not crank.
