Hi it started up ok when I connected to another car battery left it running for over an hour and it’s still only holding 11.2 volts no error messages but it’ll happen again as clearly the battery is not holding a charge thank you guys Andrew

Ok thanks will try this tomorrow presume can just put jump leads over from another car even with its engine off see my video I took earlier today hope it confirms your thoughts as I had over 11 volts once I charged it up A1F49076-62FE-4BF7-A952-723F6CE66E73.MOV

Can someone help, I’ve got my brothers Lexus is300h in my drive as he’s working away, the auxiliary battery in the boot keeps discharging so I disconnected it took it inside and gave it a deep state charge. when I reconnected it the alarm sounded, lights flashes and dash lights all flashing at random, eventually got alarm to silence but all lights on dash flashing as if something needs reset, When I press the start button it asks me to press the brake and press the start again, the hybrid system tries to fire up on the screen but won’t fire up nor the engine start, it reverts back to various dash lights, hazards flashing and horn low tooting any idea how I reset things? thank you Andrew
