This information was perfect for my 2012 RX450H. and it saved me about $200 by doing it myself compared to the dealer. Thank you! I tried a comparable battery from Costco but it did not fit in the space with the support bracket. So i bought the replacement battery from dealership.

[@Viktor_G_Automotive]

Nice work getting it done yourself!

[@MacleanTrainor]

What was the battery that the dealer sold you?

[@paulkern9380]

Great video. I like the additional details on the cover panels removal Lexus adds, the add-on at the end for addressing the reset by using the close button on the hatch.

[@Viktor_G_Automotive]

@@paulkern9380 thank you for the positive feedback Paul!

[@gegwen7440]

Thank you Victor & for all those little “tips” like getting the auto closing button to wake up.

[@Viktor_G_Automotive]

@@gegwen7440 my pleasure!

Hi viktor. I have 02 sensor high voltage on engine light. P0138 code. Is that a simple fix that can be diy? Lmk please.🙏

[@Viktor_G_Automotive]

@@annsrivi most likely the sensor needs to be replaced. It’s not very difficult, but once in a while you can run into a seized one, which can make it more complicated.

How can I find a fully compatible 12V battery for 2013 RX450H?

[@Viktor_G_Automotive]

@@along4404 you could get it from the Lexus dealership or contact a reputable battery manufacturer and they could guide you in the right direction.

[@notoco1199]

Did your power door closed freely when you press it down? Mine have to be released by pressing door lock mechanism on the inside of the door. Now i have trouble programming it 😢

[@Viktor_G_Automotive]

It’s supposed to close easily.

[@tedterry4154]

Recently found standing water in my 12v battery area in the trunk. Any suggestions?

[@Viktor_G_Automotive]

Could be leaking through the rear hatch seal or elsewhere. Remove battery cover in the hatch, fold the rear seats, climb into the trunk area and have someone pressure wash the vehicle exterior to try to locate the leak.

What amp battery should I put in a 2010 RX450?

[@Viktor_G_Automotive]

@@saytanjack9097 the cranking amps are not too important since the 12V battery doesn’t turn the engine over, the hybrid battery does that. Just get a vented battery that fits properly, you could check with your preferred battery supplier to see what they recommend.

[@tonishamuhammad14]

Greeting. Where would the second battery be located? Is the considered the main hybrid battery?

[@Viktor_G_Automotive]

The main hybrid battery is located under the rear seats.

[@mauwuang874]

Can I get the aftermarket battery from local store?

[@Viktor_G_Automotive]

As long as they carry a compatible battery, yes.

[@dionnguyen8874]

What kind of 12v battery do I buy?

[@Viktor_G_Automotive]

@@dionnguyen8874 needs to be a vented battery of the same physical size. I would suggest checking with the battery manufacturer of your choice to see what they recommend.

[@originalgibbs1584]

How many KM or miles does this car have ?

[@Viktor_G_Automotive]

@@originalgibbs1584 that was a long time ago, unfortunately I can’t recall at this point.

[@josiahfrederick1602]

Must it be an agm battery?

[@Viktor_G_Automotive]

No, could be any vented battery

[@josiahfrederick1602]

@@Viktor_G_Automotive where do you find those in Canada other than the dealer

[@GP___]

@@Viktor_G_Automotive Why AGM? Is this battery used as a power source when the status Ready is on?

[@Viktor_G_Automotive]

@@GP___ Hi, I revised my earlier answer. It does not have to be AGM, just has to be vented. To answer your question, the 12V battery powers all the electrical components in the vehicle. The hybrid traction battery powers the wheels and charges the 12V battery through the DC-DC converter.

[@steveshih4622]

His long would this battery last?

[@Viktor_G_Automotive]

Depends on your ambient conditions and driving habits. Usually between 5-10 years here in Canada and regular driving.

[@charlieshull9356]

This procedure is correct for a 2020 RX 450 h but not for a 2020 RX 450 hL

[@Viktor_G_Automotive]

Correct, the long models have a slightly different setup.
