The battery in a Lexus NX300h is located in the rear of the vehicle under an access panel in the cargo area. This is different than the standard version of the vehicle due to the hybrid system that is used in the car. If You need to jump start Your vehicle there is a positive jump terminal and a grounding post that can be found in the engine compartment and You can connect jumper cables to that just like a normal car. You will want to make sure to avoid trying to juMPVia the hybrid system because it can damage the 12 volt system in another vehicle since the voltage is much higher in the hybrid battery packs.
