EV Hybrid Charging question
Discussion
My boss has a Lexus RX450H hybrid maybe a 2010 model it's battery went flat and I have no idea of what battery mode to charge it on. I would ask him but he is away at the moment.
I have looked on the net but I am confused of which charging mode to use on the C-tec multi mxs charger. It has a picture of a bike, car, AGM, and recond.
Any ideas?

Assume you are talking about the 12v battery , in which case is just a standard car right?
You are not charging the small lithium battery it uses as part of the hybrid system.
I moved it a about 6 weeks ago and just parked it up, today I went to move it and everything was dead. I opened the door with a key as the fob wasn't doing anything then put the jump pack to the terminal in the fuse box as per the manual. Started it and it ran for a bit then took the jump pack off, it was ticking over nicely then it turned itself off. I repeated the jump pack thing a few times as it kept running then turning itself off. So that is as much as I can tell you. I am a V8 man and this modern stuff is a bit foreign to me.

As far as I know they have a 12v battery and then a drive train battery, even full EVs. You just need to find the 12v battery and stick it on charge and replace if it’s now totally dead. The voltage levels of drive train batteries are different and no good for routine car stuff like windows, seats, dash, stereo etc that have been 12v for years (accepting some very new German cars are opting for a higher voltage but it’s still separate)
Thanks for your help guys.
I had a look to see where the charging leads went to, I found they were attached to the 12v lead acid battery under the boot floor. Panic over now as I was a bit worried that I might have wrecked something if I had put the charger on the thing an fried a ecu or something along those lines.

Did it turn itself off as in shut down entirely or just stop idling? If it has warmed up and you aren't actually moving it will stop idling as that is wasting fuel. It should then just move on the battery or fire up the engine when it starts moving. I think you might be mistaking the normal operation of the car for some sort of fault. Either that or it has some major fault. As long as it says 'READY' on the dash it is good to go.The 12v battery on these doesn't usually do all that much. If there is charge in the high voltage battery it just runs the electronics and the high voltage one turns one of the motors to start the engine. If the high voltage battery is dead, then the electronics turn the 12v into high voltage, which it may struggle with.

Yes I think your correct in regards to the stop start I had kind of thought that may have been the case at the time but just wasn't sure as I haven't really driven it very far. The Ready light you are talking about I had noticed. All is good now as I had charged the battery and dropped it back to boss man house, I had checked the battery for voltage and it was 12volts+The 12v battery on these doesn't usually do all that much.
