12V Battery Issue Lexusrx400H

[The Undertaker]

Hi I bought a 2009 RX400h on the 8, 8, 13 and have been very pleased with the car however, I recently went on holiday for two weeks and parked in the 'meet and greet' car park in Manchester airport.

On returning the car had to be started using jump leads as the Battery was below that to turn over the motor.

I inquired at Lexus Cheshire Oaks and the service gentleman said yes this is a common problem with Hybrids. He checked the Battery state and it was satisfactory but every time I leave the car for two weeks I am expecting to have to boost the Battery before it starts, this will mean a breakdown attendance.

Has anyone experienced similar issues and is there a solution??

Hello and welcome to the LOC.

Yes I'm afraid to say the RX400h is quite well known for this issue and has been discussed many times on this club.

Some other members have suggested the fitment of a Solar Power trickle charger fitted by modifying the cigar lighter socket to a permanent live feed and then leaving the panel on top of the dash.

You can find them on ebay/amazon for a reasonable price.

Not particularly good though for a Battery powered hybrid which has a flat Battery after 2 weeks I must admit.

replace the Battery with the Bosch replacement, it has a slightly larger capacity which will give you a few more days unattended. You should be ok to leave for two weeks without an issue.
