Dead battery on my Lexus LS 460. Try putting the battery

Customer Question

Dead battery on my Lexus LS 460. Try putting the battery charger on but as soon as it starts to charge I hear a clicking noise from the engine compartment and the battery charger stops charging. Any idea what is up?

Are you still have an issue with your Lexus?

Customer: replied 11 months ago.
We had to remove the battery to charge it. Once removed the charger worked fine. Why wouldn't it charge while attached to the car?
Expert:  Jeromy Madison replied 11 months ago.

Ok, that was going to be my suggestion.

I have noticed that vehicles that have a large electrical draw may be very difficult to charge in the vehicle.

The issue may be with the charger itself and the level of output. When charging a battery initially it takes a very high amount of amps to overcome the vehicle draw, and if the charger is fighting this draw and the draw of the dead battery it can be difficult. Also many of the new chargers are computer controlled and will stop charging when it senses too much of a draw.

I am glad to hear that you were able to charge it.
