Mine did. Mine said toyota for Lexus or something like that and it had 550CC stated on it. I just replaced mine from Sams club. I got a Energizer 24F with 770CC. Cranks with no issues.

 

Then that old battery was a factory replacement, but not the original battery that came with the car when it was brand new.

 

I just took a look at my 2014 RX battery, and there is a sticker on it with part number (28800-0P031), CCA (582A), and RC (125 min.) Group 24F.

 

Our 2010 IS 250 with only 7000 miles has had its battery fail while sitting in our driveway, five times since new. We did learn that the driving light switch should be left in automatic. We have been doing that! Last week we returned from a two week vacation and the car was dead. The company contracted by Lexus reported that the voltage read 1.8volts. Their test also showed that the battery, less than a year and a half old was beyond rejuvenation. The car now sits at Lexus Watertown. We have been told that we don't drive it enough and that we should have a trickle charger installed. There is no way to judge the capacity of the battery or know what the amperage draw is when the car sits for a few weeks. Some people have suggested that the car should have an AGM battery. I have over $2000 worth of Lifeline AGMs on our boat and they are the correct battery for a sailboat that has all the right charging equipment. I would never use an AGM battery for a car that was being driven limited miles. I would like to know what kind of battery is the OEM battery in our car and what is its amp hour capacity. I would also like to know the specs on alternator to include its output curve. I'm told that there is equipment in the vehicle that never sleeps .I would like to know what that amperage draw is. draw is.
