Battery Problem QX4 Solved
Thanks to all for your comments. Problem solved.
Here is my original note: ************************************************** ******************************** I have a new 2003 Infiniti QX4. If I let it sit for 3 days or more, the battery needs to be charged .. it will not start. I took it to the dealer and he checked the battery. It checks out good on his meter showing no bad cells and a normal amp/hour rating. According to their policy, they cannot replace the battery because their test unit shows it to be OK. Obviously, by the time I drive it to the dealer it has fully recharged. As I see it, there are two possibilities: the battery is defective and looses its charge over the 3 day period or something is drawing current over those 3 days. Can anyone advise me as how I can test for both of the above problems. I could always go over to Costco and pick up another battery for under $50 which would be the easiest thing to do if it were a battery problem. However, I would like to accurately diagnose the problem since I am under warrantee. ************************************************** *************************** I took the car back to the dealer for another checkup since the problem remained. This time I took along my old (but good) Motorola battery tester (made by Midtronics in 1973). When the dealer tested the battery it read out at 475 CCA. My tester read 360 CCA. The dealer cannot replace the battery unless he gets a printout that shoes a defective battery. He was nice enough to connect his meter to a defective battery and get a readout that showed "bad battery". He then replaced the battery with one that has a 675 CCA rating. It has been 2 weeks now with no further problems. With the old battery, the CCA rating would drop at least 75 over a 24 hour period. With the new battery the CCAs do not drop at all .. actually remain at 667...even after 48 hours. Thanks to all who replied. Norm |
