Lexus RX450H Hybrid Battery Removal & Reinstallation (2010-2015)

[@jsol2480]

I keep reading and hearing that the lexus hybrids last upto 200k miles or more if its "properly maintained". Good to know that debris and dog hair will affect battery the battery life as well because of the cooling. Very helpful video thank you!

[@PalmettoBatteryPros]

Thank you!

[@hellohanglung]

Thanks for the video and the detail steps that you captured the most in the video. Very detail and you did not hide anything. Very good and professional!! Thanks again!!

[@GaryArchie]

great video--couldna done it without it!! I ordered a factory OEM battery. Was totally surprised when I saw that I had to disassemble my old battery and remove all the wiring. Not a job for the faint of heart!!

[@PalmettoBatteryPros]

Sounds like you made it through. I appreciate the comment. Apologies for the late reply, I’m swamped with work and backed up on video production.

[@unebonnevie]

Awesome! Thank you for showing the major steps. Looks like the Lexus owner of the RX450h in the vid is also a pet owner! Dog hairs EVERYWHERE! Those battery must be kept clean for longer lasting battery.

[@PalmettoBatteryPros]

Thanks for watching!

[@JosBakker1970]

Awesome video, very clear! Only thing i would like to see more is how you test the battery and determine it is bad, and needs replacement or repair if possible. Plus where you can best buy a new battery.

[@PalmettoBatteryPros]

Thank you very much. We ship them directly from the manufacturer to insure proper balancing.

1:34 Power is off - can't move seats. need to move Seats BEFORE disconnecting power. thanks for the video!!!

[@PalmettoBatteryPros]

Yes, I just hooked up the 12v to move seats.

[@eleanormassaro5195]

Is this specific to the hybrid RX? Because I can move my power seats forward and back without turning my RX on, but mine is a regular RX 350

[@roccit]

Excellent video, thanks for this! Learned a ton!

[@PalmettoBatteryPros]

I really appreciate your comment Rocco! Thank you.

[@victorting234]

Thank you so much for the detailed DIY installation guide. May i check with you, how these cylinderical type compared to the prismatic type? Are both do the same in term of performance? Is the cylinderical type good enough and as good as the original battery? Seems the cylinderical is easier as it come bundled and ready for swapping out the current bad battery.

[@PalmettoBatteryPros]

I've been selling and installing these kits with the same manufacturer for 5 years now. I give 4 year warranties and they are rare to none. I have been very pleased with this product.

[@pmacc3557]

I wonder how much a new battery costs? Would car work without it (petrol only)?

[@PalmettoBatteryPros]

The car must have the traction (hybrid) battery operational and the cost for the aftermarket rebuild kit is $3850 out the door

[@lancehunt2699]

Same code popped up on my 2010. Ordered a used battery out of a crashed vehicle on ebay its about to be here.. my battery in the car now works for about a 100 miles give or take until i throws the code.. 179k miles. Should i check to see if theres something simple in the battery that needs replaced or just replace the whole thing with a new battery im getting? Thanks!

[@PalmettoBatteryPros]

it’s taken me years to figure out how to properly inspect, analyze and recondition these batteries. Also, I use expensive machines to test/balance modules. Given the worth, I’d see if anyone/dealership would give you money for returning it instead of trying to fix it. At 179k, the modules are low in capacity and having trouble balancing, In addition to corrosion related issues with hardware, harnesses and bus bars.

[@ArLope-vw7fq]

Great Video thank you, I have the same one but i have a P0A7A code, do you recommend replacing the entire Generator inverter? Thank you

[@PalmettoBatteryPros]

I would recommend taking the vehicle to a dealership for proper diagnosis.

[@sparklemoss1027]

Like your attention to detail

[@PalmettoBatteryPros]

I really appreciate that. I always try to find a balance between too much and not enough.

[@paulcamalin5236]

Could you answer this question please if you have experienced that? I replaced the batteries on two RX450H. After 2 years and 15,000 miles on each the permanent code wont go away and I do not get any code on the panel and the car works normal. It's just that the permanent Code P0A80 (Replace Battery Pack) wont go away. Thanks!

[@PalmettoBatteryPros]

If the batteries didn’t show signs of weak modules or unbalancing I would check the 12v. I’m sorry, I’ve never encountered this situation.

[@paulcamalin5236]

@@PalmettoBatteryPros No in fact the 12 volt battery is new. If there was a problem it would have shown on the panel. There is no problem with the battery and I. know all the battery modules are OK. I think this is just what Lexus does so that you have to take it to the dealer to clear the code and charge you a thousand!

[@lancehunt2699]

​@paulcamalin5236 have you ever figured that out?

[@paulcamalin5236]

@@lancehunt2699 I called a hybrid battery shop and they said this is always the case with rx450h.

[@malehousecat]

Based on your experience with these vehicles, if properly maintained, at what mileage should we expect them to fail and if buying used, how can i tell if its failing during a test drive?

[@PalmettoBatteryPros]

Great question. I normally see these vehicles between 150-220k. The biggest factor is dog hair and debris around the 3 vent intakes under the rear seat. If the vents are cleaned and the car was properly maintained, the battery could see 200K+, very unkept vehicles, especially with dog hair, can have battery problems around 150K or sooner. As you can see in this vehicle, the battery compartment was extremely dirty and this caused this vehicle's hybrid battery to fail at 145K. I recommend having diagnostics run on the vehicle to make sure there aren't any codes present and also check the 3 vent intakes for any debris or blockages. I would be weary of any hybrids over 150K that have signs of debris around the intakes. Check the screens behind the plastic vent covers with a flashlight. If any debris, the battery has been and is being stressed.

[@malehousecat]

@@PalmettoBatteryPros Thanks a lot. This has been very helpful. Will look out for that in my search.

[@tallsmile28]

What would be the estimate of how much a battery replacement would cost, parts and labor???

[@kubanskiloewe]

i have now 300000km on my 2010 RX450H and all is good but every year inspect these cooling filters and work of the 3 batterie cooling fans !

[@joelf5565]

@ kubanskiloewe Where are the cooling filters? Are they behind the vents and easy to access?

[@jean-philippeboutin4633]

Hi palmetto battery, how do you test or measure the batteries before re-installing the vehicle interior? Or do you simply reconnect everything and hope it works?

[@PalmettoBatteryPros]

If straight from manufacturer, install and good. If it’s been sitting for 4+ months, level charge the battery before installing

[@MrDeadlyDestroyer]

Hi! I just replaced mine today! I have an issue! After reinstalling the new one from the dealership, i am unable to start the car and I still get the P0A80 code! Do I need a specific scanner to clear the code and reprogram the new battery to the vehicle?

[@cartoonboys5]

Did you fix the problem?

[@cartoonboys5]

?

[@BraveHelios]

Great video, thanks! My wife has the same car . Does this car have cooling fan(s) for the hybrid battery and if so, where are they? Can I inspect / access them without removing the seat? Thanks!

[@PalmettoBatteryPros]

The fans are on the back side of the battery. You would need to remove everything to get to them. I recommend just keeping the rear floor area as clean as possible.

[@BraveHelios]

Thank you!@@PalmettoBatteryPros

[@cartoonboys5]

This is a great video, can i do this myself if i purchase the new battery😮 pack? Some friends i have told me its very dangerous?!

[@typenn84]

8:08 I noticed those arent lock nuts that came off the battery pos and neg. My car just smoked up after about 4k miles after installing the new battery. Im still trying to the car back running but those two bolts backed out and were loose. In the case of the negative terminal it actually fused the nut to the bolt. I guess what Im getting at is Im going to use lock nuts when I finally get everything figured out and reinstalled. Hopefully that's all the cause my car to break down on me on the highway. There was a suddenly loss of power and smoke coming from the back seats. The day prior I smelled something burning. I can send you some pictures, my battery junction block is done as the plastic melted away.

[@PalmettoBatteryPros]

I’ve never had the nuts back off and I’ve done hundreds. Is it possible you didn’t fully torque down or left loose? The burning/fusing was from a loose connection at the ground. Any fault codes?

[@typenn84]

@@PalmettoBatteryPros P0A7A and P0A94. Im hoping the root cause of those are the battery connection. It melted the junction box so im awaiting part to replace that and repair the cable connector

[@Dreancaidi]

How did you move the front seat all the way forward with the battery disconected? Do they run on the Nickel battery?

[@PalmettoBatteryPros]

The seats operate on the 12v system. I probably just connected the rear 12v to move the seats.

[@kubanskiloewe]

i have the same car but they are ok. I think the batteries in the car shown went bad because of all the dirt and dog hair which blocked a proper cooling !

[@PalmettoBatteryPros]

That is the one thing that brings these vehicles in as early as 120K miles instead of 200+.

[@kashifnyc]

My has just clocked 233k. Had the hybrid cooling pump code on, I had it replaced then the guy said, that battery code was popping. I think it’s time for replacement. Is it worth spending money when car fax is giving me $6500. Battery will cost me couple of grand or so? What should I do?

[@PalmettoBatteryPros]

Its a Lexus/Toyota, so the car will run forever if taken care of and a hybrid battery replacement. If its in good shape and its just the battery, then I would repair the battery and keep the car/no payments. I'm actually looking for a well kept 400 or 450H right now with a bad battery.

Hi guys. I have a question for the owners of the RX450h or anyone having experiance with it. Currently driving Prius Plus 2016,which has a small hybrid battery under armrest and heard only positive stuff about it. However, I am in love with RX450h and would love to get one. Should I stay clear off the high mileage RX 150 000 miles/250 000km or with good service history I should go for it? Or mybe better pay extra for lower mileage? Greetings!

price? are they brand new? what brand? warranty?

[@PalmettoBatteryPros]

New and $3650 shipped for the rebuild kit.

[@neilbarnett3046]

(UK) Toyota say they now have a 15 year warranty on the hybrid battery, as long as you have it checked annually, separately or as part of a service. This is a specific check, not just a glance at it. I had it done separately, and it took 10 minutes, nearly long enough to drink the cup of tea the dealer made for me. Quite what happens if your battery turns out to be dicky, I have NO idea, maybe they change one cell, maybe all of it, maybe charge labour, but my 2009 RX is still fine.

[@PalmettoBatteryPros]

Seems like a really good option.

I noticed you moved the front seat AFTER disconnecting the 12V battery. How is that possible? Was that a mistake in your video? BTW thanks for this. I'm going straight to my wife's car and clean the battery vents!

[@PalmettoBatteryPros]

I may have moved it forward at some point by just hooking the 12v back up. Can’t remember. Vents are super important, and if you notice water getting in the cabin (via worn seals) address it immediately. The water settles at the lowest point which is unfortunately at the battery opening where the main HV cables attach to the battery.

So let me get this straight..You are sitting on top of a high voltage battery set-up? That's not for me...I guess I won't be buying a hybrid vehicle anytime soon..Plus, how much does a replacement battery cost?

[@Obtite]

a replacement battery is about 2000 bucks, but its not common that u have to replace it. the rx450h is just like any other lexus, reliable. + sitting on the battery doesnt really matter, lets say u see any smoke in the back seat, just stop the car ;D car batteries doesnt just spontaniously combust.

[@PalmettoBatteryPros]

In all the years I've worked on hybrids I have never heard of or experienced a catastrophic failure of the HV battery. Ni-MH has been around since the 70's, it is not a new chemistry and completely safe. The individual modules are low voltage and low amperage.
