- Upgrade your Tesla to an advanced technology Lithium 12V battery and stop worrying about when it is going to fail and leave you stranded due to low/no 12V power. BattMobile Batteries' Director Dr. Scherer walks you through the process of swapping your 12 volt accessory battery in the Tesla Model S, this is on one of the "tough" ones which is a single motor Model S "pre-facelift" (2014 model).
To purchase an advanced technology Lithium battery for your Tesla go to www.ohmmu.com/shop and "get the lead out" of your TESLA!
We have an installation guide on our website as well. Email with any questions to sales@ohmmu.com
great video, the hardest part was definitely getting the existing battery out, but it was so satisfying to pull it out, like giving birth, as you said. I bought the Ohmu battery so installation was easy and im looking forward to replacement in the future being a bit easier as well because of the slightly smaller size and low weight. thanks.
Hola. Muchas gracias por el vídeo. Gracias a usted, he podido cambiar la batería de 12v de mi Tesla Model S P85+. Un gran like y mi suscripción. Un saludo desde España. 👍
The Lithium battery costs on BattMobile $439.- , but the problem is charging at low temperatures (no info for this found).
Usually LiFePO4 only can be charged obove 40°F (0°C). The original Tesla Battery charges from -10°F (-23°C) to + 140°F (60°C).
Great job!! Thank you for posting this.
Very helpfull and Amazing video to watch!!!! Well done !!
You showed me exactly what i wanted to know! I need access to the screen wiper assembly on the passenger side
Thanks for the how to step by step video. The lighter weight sure makes it easier to place the new Lithium battery back in place. It should also last longer than the 100 year old LEAD acid tech battery Tesla uses. Nice work.
Jeez, what a PITA. I have a 2017 dual motor S. It's different than this. I haven't had to swap it out yet, but the last time I was under the hood it didn't look this hard.
It's a lot easier. Any Model S dual motor is easier, but for the single motor I don't think they moved the battery until the facelift version.
Very useful video just the guy who was recording he just smoked too much last night but great video thumbs up
Great video Dr. Scherer. It would be nice if we could order a Tesla with this battery in the first place. Looking forward to another video showing how to do this on a 2015 Model S 70D i.e. dual motor pre face lift Model S. Many thanks.
Completely agree, I hope TESLA some day offers my batteries as an option with a new vehicle; but we're a long way from being ready for that sort of volume. We are building slowly but surely and within our means so we don't become over-leveraged and present too much risk and volatility! We will make another video with the pre-facelift D model TESLA (all XXD tesla will have same battery arrangement) as soon as we get our hands on one locally (Phoenix area)!
They should've move some of that other electronics there a put the 12v battery in that space in the center behind the frunck. This is a good way for Tesla to make some good money on battery replacement labor.
Informative up to a point, but I would re-shoot it really thinking about camera positioning for each segment. Then don’t just dismiss the reconnection the way this video does: take us through each install action right to the finished, closed up, completion. And also address the battery warning message that posters have complained about.
We have update of this particular model video in plan for this month, coming soon!
One of the windows has no power after replacement. Was a fuse blown?
Could you please give replacement battety model name.
the cameraman should take a class on how to use it and when to zoon in and out. Overall, very informative video.
and clean the camera
The Model 3 video is much improved haha: czcams.com/video/76PtZPF-Dvo/video.html
Curious what the performance differences could be in colder climates-- this might be great in Phoenix, but surely Tesla had a reason to do what they did. I'm leery of second guessing their engineers, but also running my original battery 3+ years in with the warranty running out, so likely tackling this myself.
We are confident in our batteries to perform well in a TESLA vehicle application down to around 0F... Below this temperature we believe the system will still perform but we haven't had the opportunity to properly test and verify this and find the "extreme" points where they will fail to function... So it depends on how cold you are referring to.
@@OhmmuEnergyis there any 2 year later update to this question?
@@hpartsch Performance is still, as expected, excellent in any cold weather climates we have shipped batteries to. Recently we have built our own in-house testing lab to advance this discussion further. In-house testing has revealed that performance degradation and safety of our batteries is excellent, so far we have only gone down to -25 Celsius, but our tests are at -25 Celsius for a continuous week at a time, which very few vehicles would ever experience (would have to not plug it in or garage it and leave it outside in sub -25C temperatures for a continuous week, I don't believe anyone would do this to their tesla, I could be wrong though). We are continuously going lower and lower in temperature and hope to report on -30C and even -35C and finally -40C test results in the next few months.
the video helped a lot but did not discuss the battery metal bracket removal, especially hard on the air suspension model, extremely tight space and impossible to reattach imo, are you going to offer a solution for those? or tutorial?
I have the air suspension and I found it pretty easy and obviously to navigate. Very straight forward
My Tesla keep saying batterie replace soon. I did replace it. Don’t know what’s wrong
I used 2 hours the first time. my 1999 Durango I used 5min
First Disconnect 12v battery ground, then FRL ALWAYS.

Had you considered using using SuperCapacitors instead of Li-ion cells and what would be the drawbacks to taking that approach ?
The drawback for using SuperCapacitors as a battery is that they don't have the energy density of Lithium batteries (meaning need more space and weight to get same capacity) and also they don't hold their charge well over a sustained period of time (forcing the DC/DC to be nearly always on, which would overwork it and cause premature DC/DC failures)... It's a neat idea though, generally capacitors are better suited than batteries when enormous amounts of current output are needed in a brief time, this isn't the case with a 12V battery in the tesla vehicle.
Thank you for your comments on my video!
True the energy density both gravimetric and volumetric is poor for SuperCapacitors but you only need a fairly small amount of stored energy beyond the traction battery in an electric car, just enough to keep the electronics going really. I was unaware SuperCapacitors had such high leakage. I bow to your greater knowledge on this matter.
Does installing this new lithium battery require a software update, as lithium batteries have different charging characteristics over the OEM lead acid battery? Thank you
It does not.
What year is the Tesla?
How do you reset the notification after changing the battery?
Watch our new video for best instructions that will make sure the notification gets reset. If you already did the swap go to Ohmmu.com/support. New video czcams.com/video/76PtZPF-Dvo/video.html
I thought those batteries need a different type of charger than the 12 V liquid acid battery
I realise it's too easy to criticise motor manufacturers but really, burying away a battery like that is quite ridiculous. With that amount of room in the 'Frunk' one would have thought it could have occupied a space there, as it seems to be quite small.
Yeah, but we all like big frunks don't we? Don't want to eat up that valuable real-estate... I actually totally agree with you though, some folks run a set of jumper cables (or something more permanent) from the terminals to the lugs and position the battery in the frunk for easy access. When we were doing our R&D with a Model S 85 we ran it this way to give ourselves easy access to the system for monitoring/tracking-data.
OHMMU - Have you ever approached Tesla? It would be extremely interesting to guage their response. I originally saw your installation in Rolf's cars which made me watch this video.
Not yet, have been a little hesitant since I think they would just gobble me up and spit me out... My experience working with big corporations on pretty much anything has been disappointing overall...
@@OhmmuEnergy That's understandable. Elon has stated in the past that Tesla tried looking for an alternative to the 12v lead acid battery but didn't find anything @ the time. Perhaps your products weren't available @ that time. Maybe if you tried dipping your metaphorical toe in the water? It would be fairly important to be able to supply @ scale prior to any approach given Tesla's explosion in their rate of production in order to have any chance of them taking Ohmmu Energy seriously should your product prove to be potentially viable from Tesla's point of view.
Tesla have very tight margins & judging by the Q4 earnings conference call likely to get tighter & I'm guessing this also applies to their arrangements with suppliers. I've no idea if or how your company would be a good fit under those conditions.
Tesla may prove to be different & if not, previous experience will @ the very least have highlighted the pitfalls in advance. Contractually speaking, this would mean ensuring that you leave adequate escape hatches @ each stage of any agreement in case you feel the need to jump ship. At the risk of telling my granny how to suck eggs since you've been in business for some time, I can only assume you've ensured that you own the rights to your technology, preferably thru patent/s.
Nothing ventured, nothing gained as the saying goes. Best of luck should you decide to see if the waters are warm enough to swim in.
I wonder why Tesla put LEAD batteries in there Car's in the first place. Defeats the purpose of saving the environment if you're not 100%. I hope they have recycling plans in place for all broken down Tesla's. Would like to see a continuous loop for all Tesla vehicles.
When I was at the grand opening for the Gigafactory last year in July Elon and co mentioned this is something they are working towards (full loop of recycling and reusing the lithium battery contents). Yeah, I think they did LEAD because it is cheap and well-known in the industry (automotive) vs. try to create a new 12V battery altogether, it was simpler for them to get up and running...
Why does Tesla need a 12v battery at All? A 12volt converter tied to the 85Kw battery wont do?
What happens when you just took a long road trip and are pulling into your destination with only 1-2kWh left in your battery (heck, say 10kWh left) but won't be able to charge for a week or two... The car's computer systems (and other 12V loads) are pulling ~60W all the time so that is 1.4kWh per 24hrs; you would deplete your main-pack to absolute 0% within a few days in this scenario and once you've done this all your computers would shut down... Once they have shut down, you can't plug the car in and get it charging b/c there would be nothing to establish communication with the charger and start things off in the charge cycle...
Well, without the 12V battery this scenario results in a $30-40K battery replacement. Having the 12V battery there is essential to the safety of the vehicle in certain scenarios.
I understand it isn't an "every day" thing for most owners to use the vehicle that way but if it would be a "fatal flaw" quickly pointed out when it did happen (and certainly that situation happens all the time somewhere in the world)...
Cytranic I honestly don't know why they need a 12V battery. I only assume it's used as a backup system more then anything. The more stranger question is why did they use a LEAD battery instead of a Lithium battery in the first place.
The Tesla needs a 12V battery system because only the drive units, cabin heater, and A/C run on the main pack DC power (400V). All other systems, including electronics, computers, power windows, etc. run on 12V because that's a well-established automotive standard. In addition to that, safety requirements for electric cars require that the main pack DC power (400V) run through a contactor that can shut off the high voltage when it's not needed. When the car is parked, that contactor drops out, removing high voltage from the car. The 12V is needed to run the electronics systems and then power up the contactor when the main pack is needed again.
A lead-acid battery was chosen for the 12V battery because lead-acid chemistry can handle powering systems in very cold weather and can be charged without a temperature management/BMS system..
the rubber topped screw (to lift off the side panel) absolutely refuses to budge. More likely to rip the rubber head off than be able to unscrew it to remove the panel. Very frustrating.
Use a thread penetrator and make sure you clean the heck out of it when you do get it out. Corrosion makes them tough, usually there isn’t any but when there is its a pita!
@@OhmmuEnergy In the end I had the mobile tech from Tesla do it and he appeared to reach in through the nose cone and unscrew it from underneath!!
FFS Only Telsa would make accessing a 12V battery rocket science because #SpaceX
Thank you for the video. I have a problem with this code Bms_u019.
do you know what caused this and how to fix it?
Usually codes that begin w/ BMS_ are sourced from the HV battery and are issues in the High Voltage system, not 12V issues.
thanks for the howto, but now how do i get rid of the battery warning on my dash?
Ditto
Mine went away immediately
Your Brave you did not tape those terminals!
Is there BMS on Lithium battery?
Yep, we have a BMS built-in to these batteries
Sean Scherer - do you still sell these batteries?
Not sure what the point was of removing the Frunk Microwave box... and seriously time to re-film this
Did refilm, tons of editing needed before can go live tho, tedious install process means tedious video editing...
@@OhmmuEnergy still editing after 1 year?
how much is a battery
watt?. why have batery. is not a electric car?.
Nice…
but I’m not paying $439 on a damn Ohmmu battery
Even after seeing what a pain this battery is to change? Do the swap once and you'll pay the extra to avoid doing it again any sooner than you have to!
@@OhmmuEnergy … no
My OHMMU battery stop working after 6 months, the company won’t refund. I mailed it back . $400 loss lessons learn , let tesla do it for $136.59
3 times the cost , extra work, I made an appointment with Tesla, they came to my house. Put in a battery , why pay 3 times the cost and get your hands dirty, just make a service request, Tesla will do it .
very complicated
It's not too bad once you've done it, but certainly it is way more complicated than it should be and more complicated than a typical vehicle (Prius are tough too)... The D model TESLA vehicles are easier because the front motor forced them to move the battery to a more accessible location.
Agree. Not convenient and seemingly not meant for the owner to do themselves without a hassle. Way way way too many pieces to remove just to access the 12V. Geez is the windshield coming out next? Annoying when it didn't have to be designed that way. There is no way in hell I would have figured how to access the battery without messing something up or losing a bolt without the help of this excellent video, but now that I know, I'm keeping my appointment with the mobile Tesla mechanic so he can do it! Ridiculous. The new battery better last more than 3 1/2 years like my original late 2015 Model S one has...
Why would you bother to shoot a video (intending to publish it) with a dirty lens?
all that technology to remove a battery lol
It’s a no for me chief...
jee. zuss. what a ridiculously complicated process.
Agreed, and unnecessarily so, right? The later models do a much better job!
I am swapping in my Battmobile battery right now and your instructions SUCK! You skip over the whole battery strap and its little 8mm bolt. Also no mention of how to get the little hooks to stay. I could have swapped the 12V battery in our Rav4EV 20 times by now and I haven't even got the original battery out.
your giant head is right in the way and the video gets all tilted right at the crucial time. Ug.
I'm sorry our instruction manual isn't better. Do you have a telescoping magnet? That is very helpful for that portion of the swap. You can get one on Amazon maybe prime can have it to you in few hours? www.amazon.com/SE-8036TM-NEW-Telescoping-Magnetic-Capacity/dp/B000RB3XBA/ref=sr_1_1/137-3971689-1332207?ie=UTF8&qid=1496019401&sr=8-1&keywords=long+reach+magnet
Best way to get the little hooks to stay is to actually use duct-tape on them, tape them into position standing straight upright.
In my video here the vehicle didn't have that strap in place prior to the install and I didn't add it back in either, they likely left it off because it is a headache and I wasn't going to disagree with that presumption and add one back in there!
You are right, this is an over-sight for sure, we wrote the instruction manual based on this video so that element was missing from the manual as well. The two best bits of advice: telescoping magnet helps to grab and align things and duct tape helps keep the support arms in place until you get the strap back in place on top.
What a badly designed convoluted process. Come on Tesla, you can do better than that surely?
They have this is an early model
