BATTERY

2004 Lexus GS 430

Electrical problem
2004 Lexus GS 430 V8 Four Wheel Drive Automatic 42000 miles

I have had to replace the battery 3 different times now within the past year. Dealer did diagnostic test and found nothing wrong with the car but yet the battery continues to die and fry. I use this car very sparingly and there are times when it is not used for 2-3 weeks due to my travelling out of town and having a second car that I use also. Any idea why this is happening.

Hi there,

Do you know what the alternator out put voltage is, if the battery is cooking, you may have a over charging problem.

Either the alternator is not putting out or you have a short somewhere in the electrical system eating up the battery-Brand new battery for 2-3 wks it should be able to start then again it depends on the weather condition
