- In this video I replace the battery in my 911. Porsche recommends reprograming the car for the new battery, however we are not doing that. We'll see how the performers and if there is any difference in the life span. Below are the links for the tools I used to maintain power to the car while removing the battery.

Great Videos!
I purchased a 991.1 CS about a year ago, and now I'm checking out videos on how to maintain this car. Your library of videos are a great resource for this, and I've watched a few of them, but need to watch more. I like the AOS replacement vid as that part is difficult to see and get to.
However, what I like best about your videos is you're real on them and say what you feel, which many times I feel the same way...like the additional cost of the battery, your reply is "whatever"...LOL!
Mahalo for the videos!
Lol. Thank you! I can be a bit sarcastic, that’s for sure. I appreciate your comment and thanks for watching the videos!
I enjoy very much seeing your videos! It looks like you are very perfectionist and meticulous guy, you keep perfect and neat that gorgeous 4S! Congratulations!! With my only intention for help, keep in mind this important Safety Standards: “When a battery is replaced , always remove the negative cable first (ground), then the positive cable. When you connect the battery, connect the positive end first. So the order is: Remove black, remove red, attach red, attach black.”
Alejandro Rubio thank you and thank you for the safety reminder. I know this but with the distraction of making the video I just completely forgot. Thanks for pointing it out and I appreciate the compliment as well.
I change batteries on almost all European cars. BMW, Audi, Landrover and Porsches all have to have a BMS ( battery management system) reset. The computer regulates how much energy it gives from the alternator to the battery and the older the battery becomes, the more energy it gives to the battery, so if you change it without resetting the bms, the computer will keep overcharging and will eventually burn out the battery prematurely. The PROPER way to do it is to reset the BMS. If you own an expensive vehicle then paying another $100 to save a potential damage shouldn’t be a problem. You play in the rain, you deal with the mud
Thanks! I actually did buy the icarsoft updated version and reset the battery
Thanks for the great video! I just changed the battery on my 2019 Carrera S 991.2. OEM was Banner 80 Ah 800 A EN, I upgraded to Everstart 95 Ah, 900 CCA. 4 yr. Warranty. $179.95. Clarios, formerly Johnson Controls, makes this Everstart for Walmart. Clarios also makes Varta for Porsche & many other brands of AGM batteries. My 2 T-screws were T-20 & not T-30 like yours.
Glad it helped
The only reason why I'd think that your car would have to be programmed to have a certain battery installed is if it had a different chemistry. If you went from lead acid to a lithium ion type (smaller), the current and voltage to charge it would have to be set differently. The logic you used: use exactly the same battery and installed it yourself, just saved you several hundred bucks. Good man!
Like your other videos too!
That just isn't true. Newer cars require programming because the alternator is computer controlled. I'm not sure of the reason or what happens if there's no programming.
Thank you for the compliment, and it’s actually an algorithm programmed into the charging system on Audi and Porsche. Changes the charging curve as the battery ages. All these years and I’ve had absolutely no adverse effect. However, if you drive the car every single day, it likely adds some time to the life of your battery.
Hi. Just want to say thank you for making this guide. Just put in a Bosch LN5 agm into my 991. I didn’t use a battery tender and only thing that got reset was the clock.
sounds good. all this time and i have not had a single issue.
I just changed the battery after 7yrs on my 911 ts. Did it without keeping the power on and everything was fine. Thanks for the video. But the supplier from the Berner brand, plugged the obd2 and reprogrammed the settings for me.
thanks great to know! mine is going strong also. no issues at all.
14:54 Actually, you put the Negative cable on last. This way you cannot short the Positive to ground as you are swinging a wrench or ratchet on the nut of the Positive cable. And when removing the terminals, you remove the Negative first.
Thank you I know I totally screwed this up I realized it after the first comment
Great video. One thing is that instead of using power supply, you can simply use the supply option on the C-tek if you have that functionality
Thanks!
I replaced the battery on my '13 981 BS myself a few years ago with an aftermarket battery and a few months later, had an unrelated electrical issue that required some assessment from Porsche. At the time, the car was still under a CPO warranty. The dealer flipped out when, upon interrogation, they realized I had changed the battery without reprogramming and refused to cover any electrical issues until it was replaced with Porsche battery along with the appropriate reprogramming. As a compromise, they agreed to temporarily install a Porsche battery, did the reprogramming, and since my electrical issue persisted, they fixed it for me. Then, we put my battery back in, they updated the cars programming so that it "knew" the battery was new, and sent me on my way. That battery did fine and still had good volts/amps when I sold it, a few months ago. (I miss that car btw, but love my new 991.2 C2S). Who knows if that reprogram made a damn bit of difference!
Good videos btw, I used your brake rotor video to help with my girodisc rotor job last week...went great, so thanks!!
Robert Haas that’s awesome! Thank you. And agreed, no idea if the programming matters. I actually called Porsche in Atlanta and spoke to an engineer who never actually said one way or another. Lol.
I am watching your video just now. I have two of their cars and I have worked on one of them and both have been several times to Porsche OPC...the stealers. In what concerns batteries: I have both cars permanently connected to CTEKs and I have been able even to rescue to full capacity one of theLiFePO4 batteries that had 'died' - the Porsche OPC who sold me the car new never told me that the battery of my second Porsche would not charge through the cigarette lighter (the poor service from the stealers...) and whilst I thought the battery was at full charge when I went to drive the car the battery had gone and it was a challenge to bring it back to life as all I was told was 'you have got to buy a new one". But replacing batteries has never a problem and never a need to reset anything. These OPCs will slick their hands with our money if we let them to
Agreed! Still going strong. Zero issues as you know lol! Thanks for the comment.
check out a video about how to register a new battery in porsche and you will find out how to do it... you did nothing actually just changed the battery there is a process about how to use your icarsoft thing to show to the car that you have a new battery on.
Yes, I now have the new device that will register the new battery. However, I never bothered to do it and I’ve had zero issues.
OMG! Stop! Stop! You forgot to wipe down that nice new battery with Clorox anti-virus disinfection special battery wipes. Better put that battery into quarantine for 14.65 days (or 351.6 hours which ever comes up first!). Good job and I'm betting your right that you, the car and the new battery will all just be fine without any PISWS re-programming! BTW, that slick, new Bluetooth battery monitor that is being sold by Li Battery supplier on Rennlist will give you some interesting battery charging data and log. Thanks for the video and looks like a good project for me to tackle on my '14 981 S while waiting to come out of hibernation!
Gus Gus thanks!! I’ll need to check out that Bluetooth monitor. That sounds interesting. And I injected myself with Clorox earlier in the week, I should be good now! Lol. Thanks for the comment!!
As a note re battery management on 991s and internet advice, when I connected my ctek comfort connector I didn’t connect to the neg but instead used a hole in the bulkhead near where you disconnected he horn bracket.
Thank you for the tip
Great video! By the way, do you have the phone mount link? Thanks !
Thanks! I don’t but I found it on rennlist. Do a search there.
Great video as always! Nicely explained and well filmed. Just one little question: What is the small square Porsche red pouch (@4:35) mounted to the inside of the trunk (held in place with a grey strap)? I also have a 2013 Agate Grey 991 (coupe) and love watching a similar car being cared for. Keep up the great videos and stay safe!
Dennis Moskovitz thank you! That’s the German version of the first aid kit that comes standard on a car delivered in Germany. Along with the red triangle kit. There are actually mounting holes under the carpet for it. Thanks for the comment and thanks for watching. I’m gearing up for a 50 things to do to your 911 to summarize all the little projects that I’ve done over the last couple years.
@@bobbygfl Ah, that's what I thought it was! Also thanks for the great tip re: Spice Jungle. Can't grill anymore without their garlic pepper!
Thanks for the video!
Thank you
I believe you take off the negative terminal connection first...
PAUL Humphrey yep. My bad. Focusing on recording not doing it right LOL thanks for coming
Good video as always 👍🏼
J J thank you!!
I have a quick question. seems like you already have porsche battery tender and couldn’t just leave the battery tender plugged in during replacement process so you won’t mass up the presets? just wondering why you purchased extra power converter.
The power converter is a constant supply of unregulated 12 V power at a constant amp supply. This is what’s necessary to keep all of the systems running while you take the battery out of the car. The battery tender provides very low amperage and actually turns itself off when the battery is fully charged. There’s a good chance it could get confused and shut off which would be a problem.
Great video. Very informative.
Can you tell me the name of the the manufacturer of the device that you plugged into the fuse box? Where can I purchase one of those? Thanks 👍!
I car soft. Scorch por2 or porII on Amazon.
Could you make a playlist about your Porsche ?
All set. Thank you for the idea. I did this about a year ago.
Yo Bobby. Entertaining video, I learned something about the OBD II port to maintain power while removing the battery. What's the diff between the iCarsoft POR II vs other models? But other than your "massive muscle" comment (LOL), why did you disconnect positive terminal first. When you read the owner manuals, it says to disconnect negative first and hook back up in reverse order. Did you ever do the PASM plug-n-play replacement by DSC Sport?
Ian D good point. I have no idea why I removed the positive first. Lol. And I was wondering if anyone would catch that strong man comment. Lol. Not. That battery is heavy af. I’m surprised I got it out. The por2 has pre programming in for Porsche codes and resets. It also has a different program that works on mini and bmw as well as others. Thanks as always Ian!
look at this video at about 13:20 ua-cam.com/video/z6xHwNPoDqE/v-deo.html
Hi Bob sent you a question a while back but have not heard back from you. Where did you get that power supply that plugs in where the OBD plug is.
Thank you.
Sami
Sorry for the late response. I got them both on Amazon. Just search 12 V power supply. And then Limited-time deal: Schumacher SEC-12V-OBD Memory Saver Adapter Cable - 12V - Save Your Vehicle Settings During Battery Removal a.co/d/7gTN4kn
I wonder about this myself. It is amazing how this seems mysterious still. Debating getting a tool similar to yours or Durametric. Jealous of that long range fuel tank :| . You happen to be doing your 7MT gear oil change anytime soon?
TheObiwantoby thanks for the comment. I’ve done it a couple times and there’s so many videos on UA-cam of how I figured I would just skip the filming.
Florida eats batteries. Based on my experience, three years is great if you have your car outside and 5 is really great if you garage.
Thanks!
Great video Sir! Was there any vent hose on the original battery?
/
Thank you! No it’s completely sealed.
@@bobbygfl Thank you! What I was referring to was the vent seen at exactly the 10:00 minute mark. There is one on each end of the battery that normally has a hose attached to one and a plug in the other. It doesn't appear that your OEM battery had either of them. Thanks.
Macan battery replacement
Thanks
Enjoy your vids, but you should have taken off neg terminal first and then positive terminal. And, car does not lose memory, so no need for external power. Otherwise nice vid.
etc etc ordinarily I would agree but if you have the car connected up to a + source “code saver” I’m not sure it makes much difference. I take the precaution of glove cover too.
I know totally agree. I think I was caught up in the filming and just forgot that rule.
very nice!!
Thank you!
Hey I have a Boxster s with the hood locked with disconnected battery’s do you think it will produce enough volts for me to unlock the hood and reconnect the battery??
Yes likely it will. Good luck!
where do I get the OBD?
Amazon.
If you already had the Porsche battery maintainer plugged into the cigarette lighter, why did you decide to use the OBD power connection? I am planning the same swap on my Cayman as soon as the battery and the maintainer arrive.
Were you able to use your tendering the cig lighter to do your batt change??
I am considering the same process...
Thanks
@@alberthilt Yes, but you have to lock the doors or the cig lighter will be disabled after 30 minutes.
@@bigmoguls9359 on my car, use the lighter socket under the dash passenger side it it doe not turn off.
The battery maintainer could shut off if it thinks the battery is full. The external power source that you see me use is guaranteed constant power no computer controlling it
You should remove the negative first. And the positive first on a new battery.
I know, I guess the filming and anxiety that I was going to screw up some Porsche programming took over!
@@bobbygfl ..its all good...Thx for the tutorial video. When I changed out the battery on my '06 cayenne S I just replaced it without using the battery tender and all system stayed normal afterwards, but I wasn't sure about it on 911.
@@johnwhodat8135 good to know. Seems they all use the same computer.
@@bobbygfl ..maybe they use same computers but I'm not taking any chances on battery replacement on my 991.1.
@@johnwhodat8135 better safe than sorry!
Hello! What model of battery and with what parameters have you installed on this Porsche?
It is the current Porsche brand glass mat battery. I got it from the dealership and I don’t know what you mean by parameters.
All good .. but you did not register the new battery type, bar code , battery capacity or battery serial number or part number .. this essential for optimum performance & battery life & charging system that control module integrity..
Nope. And it doesn’t seem to make any difference. Still going strong.
As a mechanical engineer & Porsche expert, with 35 years experience.. it does matter otherwise Porsche factor would not Suggest it .. simple procedure .. with good scanner, like Launch or autel it an be carried out in matter of minutes..
@@PARSA2152 I actually do have the scanner that will register the battery I just haven’t bothered. I agree with you. They designed it to be registered.
@@bobbygfl Bobby, by “the right scanner” do you mean the POR 2.0 in the video? I have that same scanner but, like in the video, it doesn’t seem to have the menu to do all of the battery resets (Maybe it does, I only used it once to reset my oil light for my oil change, so I don’t really know the POR 2.0 potential yet) - 2015 911 C2).
I’m actually bringing it in to the dealer as I’m getting the PCM constant rebooting… battery has never been changed, have it in storage half the year with the Porsche battery tender, 27,500km on the Odo, have you heard if your battery is running low that the PCM could start acting up/doing the rebooting problem?
I have the latest PCM 3.1, v4.76 update and pulled out the fuse to stop the constant reboot (B10 in the fuse box).
Talk soon! Hope you can help me out.
This is the link for the device that has the battery checking and resetting software. Ultimately if you’re having problems probably getting the dealer to look at it is worth the money. But if there was no other problems this device will reset it I just never made a video because I got this new updated scanner after I replaced the battery. iCarsoft Auto Diagnostic Scanner POR V2.0 for Porsche with ABS Scan,Oil Service Reset ect www.amazon.com/dp/B07F2WF96Y/ref=cm_sw_r_cp_api_i_BJTTMB8ETB579C5QVVFG?_encoding=UTF8&psc=1
try antigravity batteries ,much better in life and wight.
Thank you! I’ll check them out.
What is the exact battery you used as replacement?
I’ll need to look at the receipt. I bought it directly from a Porsche dealer and it’s the battery listed for my vin number. I’ll look though and reply again.
Is this a lithium battery
No. It’s glass mat
I've changed the battery on 2 on my 991's and never reset the computer.
I actually bought the tool to reset it but I still haven’t reset it LOL. Still no problem whatsoever
Hi Erik, do you mean just replace the battery just as normal car? Mine is time to replace. Thanks in advance.
Did you consider putting in the lightweight but really expensive lithium ion battery?
Keith Greer nope! Lol. Lost me at really expensive!!
Keith Greer wow. 12lbs. That’s crazy. I’m sure someday everything will be lithium and affordable. I was reading about a new Samsung battery that is suppose to be a game changer.
If you think of what guys pay for the Weissach versions of GT2’s then paying that much for the battery to save weight is a relative bargain
Keith Greer yes. Totally agree. When weight matters like that.
@@bobbygfl I'd skip the lithium battery. I tried one and it was fine at first (it IS amazing how light they are) but it eventually started causing the car to throw dash codes (and I even had the car randomly shut off twice). I switched back to the old one- no more problems.
What is the component directly in front of the battery? Mine seems to be making a clicking noise? Thx!
the ac system.
Porsche just wants you to take it to them, just keeping 12 volts on the wiring system should fool the car about a new battery.
I do believe it changes the charging curve like they say. But I don’t believe it matters much. I’ve had zero issue with this new battery.
I dont understand putting a 50 lb battery back into a sports car. Its a low tech part in a high tech car. The small increase in price for a lithium would pay dividends in the future, and save the back strain. LithiumMoto has a 60Ah @16 lbs and a 80Ah @ 21 lbs.
And the H7 80Ah that is in my GTS would cost $1200 from Antigravity vs $170 for an AGM. And why would you want to make my tail heavy car more tail heavy by moving the C of G further back. Lithiums are a waste of money.
@@a.c.e.7568 Well, the $1200 from ANtigravity costs $700 from LithiumMoto. 2nd, if CG is a concern, just put a sandbag in the frunk fwd of the battery. That would give you back your CG
@@andylithium1309 Well adding a sandbag to the trunk defeats the purpose of a light Lithium. LOL I'll just replace it with another AGM. The factory original is going into its 9th year, so they last. Other batteries of mine have lasted 16 and 14 years so I do not buy the false claim about Lithium batteries lasting 2x as long.
Agreed on the weight, but this garage queen doesn’t make a bit of difference lol
Pull off the GROUND (negative) cable first. Then you're not at risk of shorting anything. Then you don't have to put rubber gloves on the end of the cable.
It's not about being anal; it's about doing it correctly and safely.
When re-connecting, obviously, connect the ground cable last.
Thank you for the comment. I think the overthinking of the video process took over my common sense LOL.
@@bobbygfl Don't beat yourself up about this too much. Since you're supplying power through the OBD2 port, the positive cable you pulled off the old battery and replaced onto the new battery was going to be "hot" throughout the process anyway. That would *not* have been true without the auxiliary power, and the criticism would have been more justified. The important thing is that you broke out the rubber gloves. I do exactly the same thing with my 997-series. ;)
