12V battery voltage in RX400h
Recently bought a 2008 RX400h that is 3 years old with 18,000 miles. I had it trucked to me from a Lexus dealer who had been storing it for a couple of weeks in their basement.
The car would not start when the truck arrived at my house. It had to be "jumped". I then charged the battery (the 12V mini-battery) and it again would not start the next day w/o a jump. It did this a total of 3 times in the first day we had it. After each jump, I charged the battery. It came up to charge quickly...an hour or two.
It has been over a month now and the start failure has not repeated.
I recently bought a Solar battery tester and just tested the battery. It reads 12.01 V (consistently, engine off) and 270 CCA. I don't know what the CCA is suuposed to be (no label on battery), but 270 CCA seems low and so does 12.01V. I tested two other batteries I have on my bench (big sealed gel batteries for BMW and MB), one 9 years old and one brand new and both read 12.45 V and >>600 CCA.
I am going to have a Lexus shop check the battery in two weeks. I was curious, however, what voltage reading is normal for an RX400h 12V battery with engine off. Anyone know?
Thanks.
