my car ran out of miles on freeway and it died so bad! - towed it to my house .. thought plugging it in with the 12v charger that came with my NISSAN LEAF 2017 would fix things but it didn't charge it up at all. then I got the T/M system malfunction error. Thank you for this video so much - I haven't tried it yet but my bf and I are going to give this a try. do you think I will need to replace the battery? I bought it 8 months ago with 30k miles on it. slight used car its a 2017 Nissan Leaf.
Thanks for posting! I’m curious to know why one wouldn’t want to start the car right after attaching the jumper cables? I was thinking the battery is so small and there is no engine to turn or any task to tall to begin. Other than being wrong in the assumption that the car would start right up, what could happen? I was thinking it might be dangerous to run the other car at all while connecting the cables.
Bmilesonline, Great question and thanks for sharing your concern. The little 12 volt battery on the Nissan Leaf is really a bad setup. I was the general manager of car dealers in my younger days and when we bought Nissan leafs from the auction and it needed the transported to the dealer. The tow truck drivers would call us from the auction to express their frustration about not being able to start the leaf after the 12v battery had discharged(The tow truck drivers weren't sure if it was the main battery or the 12 battery, Hint if the 12 volt battery is dead the instrument cluster will light up for ONE second and will go black again + a weird star wars light sound effect) . So I would tell them to leave the jumper connected for at least 15 minutes before they attempted to jump ( if they attempt to start the leaf too soon it won't start). After that no more frustrated transport drivers calling to complain about not being able to start the Nissan Leaf. Attempting to start a vehicle that doesn't have a consistent battery voltage above 10+ volts isn't good for the car or ELECTRONICS. There are a lot of modules (computers) that come online the second the ignition turns on. Just because a battery shows 12 volts (ideal voltage for a 12v battery is actually 12.6) doesn't mean its really 12 volts(surface charge vs load use), especially after a battery has gone under 8 volts it might be permanently damaged.(CAR BATTERIES HAVE MEMORY, general rule if a vehicle needs a jump more than once you need to check the charging system. If the charging system checks out then load test the battery using ACTUAL load tester (don't be fouled by a surface charge reading off your battery, I put a link below about a $25 load test that I absolutely love it). If charging system and battery check out then you have a draw (short) somewhere in the vehicle) I like to let the battery on any vehicle that I'm jump-starting charge for a little before I attempt to start the vehicle not a just an EV. Leaving the jumper cables connector for 15 minutes is better than overloading you the booster cars alternator and the jumper cables. On bigger diesel trucks I've had to use jumper cables and an electrical 120v battery charger set to highest setting just to jump it. I hope that this a little charity to your question and thanks for watching the channel. -RandomFix VIDEO LINK: Slow Starter Crank or NO Crank? How to Inspect Car Battery and Charging System.

The alternator and regulator will do a better job taking it up past 11.8v. Than the Nissan dc to dc converter. Stronger current can rattle the plates too. Nissan will like a 13.1 v better on start up.
I think battery was not a good setup for the leaf. Most lead acid batteries sit at 12.6 fully charged so 13.1 is not there. Since they had spent so much money and effort on the success of the leaf they should of included an agm battery instead of the crappy lead acid battery.
I have a portable jump starter battery. Would I be able to use that normally to jump start the Leaf? Or do what you did and leave that jump starter battery connected and turned on for 10-15min? Also, if I don't have a trickle charger at home, can I just leave the Leaf turned on and will that charge the 12V battery?
Have you tried those small jump packs? I bought one from Costco and keep it in the car. First battery died at 0300 trying to get to work. Next battery was drained down so the car wouldn't boot. So the jump back allowed the car to boot. Now the battery this morning was draind down to 7 volts. You really need to pop the caps of and check water level. I had the pack on and it and car where beeping. Had to remove the negative and it stopped. Put a charger on set to 20amps for an hour and the car booted. I don't charge at the max. I'm not sure what max amps you can?
I replaced rack and pinion on leaf by removing fuse main battery in the back. after I fix I connected the fuse it is not coming out of parking mode. Do we need to reset the car? if yes, could you please help.
My leaf just died in the parking lot after beeping insanely, flashing all its lights, and death rattling. I suspect this is my issue. Thanks a lot for this, very helpful.
Bleed320, I glad I could shine some light why your leaf dead. Please inspect all battery terminals and linkable fuses that are incorporated into the positive thermal post. Be sure to test your battery and replace if needed with the OEM or even better get an upgraded(agm) battery, I have included a link in the description of the video.
John, yes I do have a video to help you get a good quality Nissan Leaf. The video covers makes/models but you will need to pay special attention to the Nissan Leafs Dash and the battery bars on the right side of the instrument cluster. Also, call Nissan before you give payment to the seller to see if there any current recalls and make sure you get a 120-volt charger and you can buy a level 2 charger on Amazon for around $250. The 12-volt battery under the hood is garbage but it's only about a $120 to replace when the time covers. I wouldn't recommend buying a leaf that has less than 10 battery bars remaining. Best of luck and let me know if you need anything else. _RandomFix The Nissan LEAF has a 12-segment battery capacity display. A new battery pack begins with 12 capacitybars. According to Nissan's service manual, when abattery pack's capacity has dropped 15%, the top capacity bar will disappear. Each subsequent bar represents another 6.25% capacity loss link to video th-cam.com/video/CYANu-jOEzw/w-d-xo.html
Can you jump a Nissan Leaf with a NOCO GB 70 charger? Are there any special instructions how to do this. Car sat for a month or so and with the cold Chicago weather, it is dead. Thank you so much for your information.
Sure you, no special instructions other than put the battery on a battery tender when you and most of the time when I a battery seats for that long it most likely never to recover. Don't get fooled into anyone telling you other wise. Here is video about it..th-cam.com/video/YXh8eEkOBlk/w-d-xo.html
Based on this video, the negative side to the nissan leaf is directly to the negative of 12 v battery in the nissan leaf. But the owner's manual says that the negative should NOT be put to 12 volt battery. Which one is right?
Because the fusible links are on the battery post. I would go straight to the battery terminal. 18 years of working on cars and I've had many of my sales staff jump cars backward. This is the safest method for the leaf in my opinion. _RandomFix
I also have advice., I own an EV/HEV repair shop. Do not even jump any hybrid or EV. I don’t even use the shop charger because it is capable of 40Amp or Worse 200Amp of charging current. Those are not safe around EV and Hybrid because the 200 amp “Start”. Put out too high of a voltage that can damage sensitive electronics. I use the small 15 amp charger and let it charge for several hours.
@@RANDOMFIX yes well one of them was the heavy duty charger which puts out over 16 volts actually zap one of my customer hybrid car, and one of my expensive scanners blue tooth. After I hooked up the charger no communications in various module!! , and the blue tooth transmitter of my scanner won’t even turn on. Be careful. I surely learned my lesson the hard way. I never jump start hybrid or EV so I don’t have a bad experience to share in that. It’s bad enough that a regular gasoline car itself is a hostile a environment for electronic device because it’s teeming with transient voltages from the ignition system, large current looking for an electrical pillow to lay lol. Most of the time it may not cause problem but I don’t take a chance when most electronics parts in hybrid cars are in the thousands of dollars. One thing I will never do is hook up a regular car that produces high voltage spikes to jumpstart an EV. Any problem with the ignition system and you got a voltage in the tune of 50k volts trying to dissipate somewhere no way not taking that chance, not trying to buy a 15k-20k dollar EV converter for a customer.
Curious why you recommend attaching the negative cable to the negative terminal on the battery? Several others say specifically *not* to do this, e.g. www.mynissanleaf.com/viewtopic.php?t=22030
Great question. On a lot of Nissan vehicle (including the Leaf) there are many fusible links on the negative terminal and since the vehicle is an EV it's just precaution to avoid a bigger headache. Now if you putting the Leaf's 12v volt battery on a trickle charger for an extended period of time you should find suitable ground like a strut tour bolt and make sure the area is well ventilated. Simplified answer: There is no engine block and if something were to go wrong I want those fuse links to blow on the negative terminal. Nissan should have installed an AGM battery. Have a great day.

Leaving the car in *drive ready* mode will charge the 12V from the traction battery.
From what I've read and experienced, when the car is plugged in using the included 120V charger, the 12V is also charged.
Sorry for the late reply! did you find a solution?
Thank you for your help in posting this video. I’m currently jumping the battery right now. Bless you friend. 🙏🏽

The jump backs work great, I'm testing a jump right now that doesn't have a battery builtin. For charging I like to keep it under 5 amps.

I honestly don't know. I try a Nissan leaf forum

My battery on my 2018 leaf just died. Thanks for the advice on what to do.
Glad to help. The cold months kill batteries.
Thanks for the tips! Never thought I’d need to jump an EV!
Happy to help!
What battery percentage did the leaf have when you charged it with the other car after 15 min?
Not sure. Most vehicles need 9.6 volts to start with a ev you may need a higher voltage on the 12volt battery to engage the ev system.

thank you for the feedback !
I use the negative on chassis or Earth lug on casing. This is only if gassing the battery, stops explosions. Doesn’t matter as it’s all negative.
Agreed
How long does the battery last ? 5000 for a new one what are the loop holes to get by battery life only 8 to 10yrs
Keep the state of charge above 20% and don't overcharge.
@@RANDOMFIX how long do they last ? 2013 57k miles
I seem them go over a 100k miles.
