Regarding a battery tender--I doubt that it would hurt anything, although, in my opinion, it is not needed. The LEAF's DC-DC converter comes on periodically (every 5 days on 2011 and 2012, not sure about the timing on later models) to charge the 12-volt battery while the LEAF is parked. I parked my 2011 numerous times (as much as 3 weeks at a time) at the airport or my office without incident until I forgot to unplug the Bluetooth interface from the OBDII diagnostic connector and left the Android device running LEAF Spy Pro on the seat. That one time, I came back to a dead 12-volt battery after 6 days. I now double-check that I have unplugged the Bluetooth device from the diagnostic port when I park for more than a couple days.

Regarding charge level--I always charged Silver 679 to 100% because I needed the range every day. I will do the same once I get my new 2015. Based upon battery capacity reports on MNL, I don't think my battery deterioration was any worse that those who charged to 80%. Charge to 100% if you need the range, otherwise charge to a lower level. As Tony said, the most important things for battery life in our climate are to keep the battery as cool as possible and avoid having the car sit at a high state of charge level. Whenever I parked long-term, my battery was at about 60% SOC and there was never any noticeable loss of charge during storage.

If you want to track detailed information about your LEAF and it's battery, I highly recommend the LEAF Spy Pro application with a Bluetooth interface to the OBDII port. Just remember to unplug it for long-term storage.

+10. LEAF Spy Pro is worth way more than it costs.

I don't unplug the adapter and so far have not used charger for the 12V and have been OK.
But I usually drive at least every third or fourth day.

A lot of troubles with the 12V were caused by using On or Auxiliary modes.
Don't do that.
Just use Ready mode with vehicle in Park and emergency brake set.
My 12V was replaced at no cost under the 3 year / 36,000 mile warranty at two year mark.
I had used On mode a lot listening to radio in garden.
It sags the 12V all the way to 10.49V before it uses the DC to DC to charge it back up.
Extremely bad for it, especially in Phoenix heat.

I heard about Leafspy and I was gonna get it and the OBD2 USB to measure the GIDS & stuff - but I have an iPhone & it says its for Android - bummer.

Nice tip regarding the On/Auxiliary vs Ready Mode. Why is that? Does the drive battery "charge" the 12 continuously in ready as opposed to when its in ON / Auxiliary? Just curious. Sometimes Ill have it in Aux while I go through some settings & mess with the GPS & programming - 10-15 min tops.

We keep the Leaf in the garage, but its not air conditioned - still gets hot inside. Parking at work is the hard part - not much covered parking!

We both use the Lead daily - about 45+ miles - so 80% covers it. Weekends we run more errands & just drive around more because its fun - we grab a charge someplace & keep goin. We charge it up to 100% for Sat morning

...

In Ready it first checks the 12V voltage, and if it is quite low will charge at 14.5V for some period of time.
But if it was 12.5V or higher it is very brief, and it drops back to holding about 12.95V on it.
Still low to really keep it full capacity but both the Prius and LEAF seem way too worried about overcharging the 12V.
So in reality they leave it about 80% or less.
If you go using Auxiliary or On much, is easy to get it below 50%.
At that point does not take much to kill it, and / or end up with a LEAF that will not start.

Best to use a battery maintainer on it once a week.
But I admit I have yet to take the time and diligence to do that.

Lead acid batteries have poor life in hot climates.
Some people report lucky to get three years.
In Phoenix a periodic battery maintainer may be much more important.

Agree on the Lead Acid 12v.

I have always use AGM batteries in my gas cars & get 8+ years in Phoenix easy. I have an Optima AGM that thats 14 years old, still holds a charge & I use it for testing & messing around in the shop.. if I top it of with the battery tender it will still start a car - but I would not place to much reliability on it for that anymore

Ill probably pop an AGM in the Leaf when the time comes & be done with it.


Also, will the Leaf let me know when 12v battery is getting to low to start reliably?

And the user booklet said its OK to jump start, but the next page it said not to jump start the Leaf - can anyone enlighten me on that?

LEAFStat will run on iPhone and it will tell you about battery condition. Not all the detail of Leaf spy, but still a good app to have.

The yellow top Optima AGM is ideal for the LEAF. The low internal resistance allows it to recharge quickly while the DC-DC converter is charging at 14 volts. The 13.1-volt float level of the DC-DC converter is also ideal for long life of the Optima.

There is not much warning when the 12-volt battery gets weak. You may have it start up fine one day and have it fail with all sorts of errors and warning lights the next. When my original 12-volt battery failed, I had a bunch of warning lights and the computers failed to initialize properly. I turned it off and on several times and finally got a successful start. I then drove straight home without turning the car off. I bought a yellow top Optima the next day.

As long as you are very careful with polarity, there is no issue with jump starting in either direction with the LEAF. The Nissan 12-volt battery has relatively high internal resistance and low capacity so it might be marginal to start a big V-8 with a really dead battery.

Jim is working on an iOS 7 version of LEAF Spy Pro.
Not available yet, but should be available for tester use soon.

The key to properly jump starting an ICE with the LEAF is that the LEAF should be in Ready mode so you are using the DC to DC converter for the jumping of the ICE and not using the LEAF battery.
The LEAF battery is very small and NOT suitable for jump starting an ICE by itself.
But the DC to DC converter is very powerful and excellent for jump starting an ICE.

Ingineer provided excellent instructions on how to do this correctly with LEAF in Ready mode using the LEAF DC to DC converter.
See:
viewtopic.php?f=9&t=6707&hilit=jumping&start=50#p283646
Follow the instructions.

Lots of good explanation on the previous three or four pages in the thread explaining why this is the correct way to do it.

Nissan recommends not jump starting because they presumed most people would do it wrong and be bad for the LEAF 12V battery, instead of doing the correct thing and providing instructions on how to do it right.

Follow Ingineer s instructions and you won't have problems.

Great - I looked in Apps Store & found it - $10 not bad. last update was July 2014, says it works with 11-14 Leafs. Any reason why it wouldn't work with 2015? Probably just haven't updated the description.

So, What is the best way to go for the OBD Blue Tooth thing (OBDC?) I saw quite a few. Any recommendations for what works best, like to get LeafSpy when it comes to iPhone, so would need to work with both. I understand to get one with v1.5, and NOT v2.1 Looked at some of the units descriptions - none listed v numbers - how would I tell before purchase?

I plan to get the 90* extension so I can have the OBDC in the cup holder.

I am favoring the Vgate ELM327 as I have read it can be easily modified to turn on/off with the car. I like that.

OBDC I found are:
• V1.5 Super Mini ELM327 Bluetooth OBD2 OBD-II CAN-BUS Diagnostic Scanner Tool - At least one confirmed to use v2.1 :-(
• BAFX Products (TM) - ELM 327 Bluetooth OBD2 scan tool
• AGPtek® Super Mini ELM327 V1.5 Bluetooth OBD2 OBD-II CAN-BUS Auto Diagnostic Scanner Tool
• Simvalley™ Mini ELM327 Bluetooth OBD2 Auto Diagnostics Scanner with Power Switch for Android
• Excelvan ELM327 v1.5 Bluetooth Mini Small Interface OBD2 Scanner Adapter Torque Android
• Newest Elm327 Bluetooth V1.5 OBD2 OBD II Auto Diagnostic Scanner Mini Adapter
• PLX Devices Kiwi Bluetooth Wireless Trip Computer and OBDII Scanner
• Vgate ELM327 Bluetooth Scan Tool OBD2 OBDII Scanner for TORQUE APP ANDROID - At least one confirmed to use v2.1 :-(- Can be taken apart easily and modified
