Is there a re-lean or adapattion procedure when it comes to replacing the battery on the NX hybrid??

[@Viktor_G_Automotive]

Generally no, are you having some issues?

[@kohkae1177]

Do you have an video for cleaning the battery fan of a 2015-2021 nx300h, heard that this must be done regularly, is that true? Thanks a lot

[@Viktor_G_Automotive]

I don’t have a video at this time. How often to clean would depend on your climate conditions and use. Here in Canada, the battery cooling fan barely ever runs, so you rarely have to clean the intake. However, if you are in a very hot climate with a lot of dust/pollen etc in the air, you would have to clean more often.

@@Viktor_G_Automotive thanks Viktor, I’m in the UK, hope that the fan is clean😅

Do you need to plug in a (car battery power saver) first???😁😁😁😁😁

[@Viktor_G_Automotive]

The repair manual does not tell you to, but I’m sure it won’t hurt.

The location of the 12 volt battery in the Lexus NX 350h 2024. Do you change its location?

[@Viktor_G_Automotive]

It is also under a cover in the trunk/hatch area.

@@Viktor_G_Automotive Is there a problem when you leave the 2024 NX350 hybrid car for 10 days without starting it?

[@victorsaleeb5632]

@@Viktor_G_Automotive thank you

[@Viktor_G_Automotive]

@@victorsaleeb5632 I have noticed that the battery on those models doesn’t last as long as some other vehicles, but 10 days should be fine, as long as you don’t have any aftermarket accessories that would stay on and draw power from the battery while the car is parked.

thank you

[@seksakpholboon3137]

what type of 12V battery can be used for Lexus NX 300h ? Normal, EFB or AGM ?

[@Viktor_G_Automotive]

It has a regular flooded lead acid battery in it, but you could use an AGM. I think EFB is used in conventional vehicles with start/stop technology, I haven’t used one of those before.

@@Viktor_G_Automotive Hi Viktor, one more question, Can I use any regular flooded lead acid battery like, BOSCH S4005, 60AH CCA540A or I need to get Lexus genuine part 28800-YZZZA? Many thanks
