Hi Everyone,

I am a new member to the LOC so I thought I would share my info on the dead Battery issue.

I work away a lot so my '57 400h is left standing for weeks on end and as other members have noted the Battery is dead after a few days of not being driven.Lexus are aware of this but there is no 'fix' unless you get the new 450h.

However,I have got the 'fix' sorted.

I got my local lexus agency to put permanent power to the lower power socket at floor level,purchased a solar power panel and leave that on the dash when I leave the car;the Battery gets a trickle charge while I'm away,the panel also has a diode fitted which stops reverse drain from the Battery.

I have not had any trouble with Battery drain since having this done.
