Looks like the OEM battery from 2011 to me.

mfg date 10/11 per the door jamb label, I think I see a Dec 10 2011 date code on the battery.

Re: Instructions for replacing the 12v battery on the Leaf (Group 51R / Optima D51R)

Decided to change out the stock 12 volt lead acid battery that my 2014 Leaf SL came with after 3 1/2 years with the Optima Yellow Top D51R battery. Was a pretty simple and easy process taking 15-20 minutes from start to finish.

- Ensured the car was parked, shut off and unlocked for 15+ minutes before battery replacement process
- Removed the old stock battery restraints and cables with a 10mm wrench (negative first followed by positive)
- Prep the new battery with a terminal cleaning brush and cleaned the connectors on the vehicle
- Applied the corrosion fiber washers to the new Optima Yellow Top D51R battery
- Placed the new battery in the vehicle, secured the restraints and reconnected the cables (positive first then negative)
- Powered on Leaf, validated all services were working
- TCU errored out, had to turn the vehicle off and remove the fuse controlling the TCU for 10 seconds and reinsert
- Signed back into Carwings

I just installed an Optima yellow top D51R in my 2015. A 10 mm deep socket fits the terminal clamps and hold down bolts. I turned the car off, opened the hood, disconnected and removed the old battery, used baking soda and water to clean battery tray and surrounding area, wire brushed terminals and posts of new battery, and then installed and connected the new battery. Power was disconnected for extended time because I was in no hurry and I let the battery tray dry before installing the new battery.

The trip odometers, miles/kWh, and elapsed time displays in the dash were cleared, but the information in the navigation system was retained. Radio presets, clock, recent routes, CarWings settings, etc. were all retained. Start/end times and days for charge timers were retained, but timers were turned off. Also, the auto up function of the driver window was disabled so I had to reactivate it by fully opening the window and then fully closing it and holding the switch in the close position for several seconds after the window was fully closed.

I started the car and used LEAF Spy Pro to check for DTCs. Four codes were present which were easily cleared. I drove around a bit and then charged the car overnight. There was no need to connect an external charger.

Did you check the 12 volt battery voltage? I don't know about Optimas, but many batteries come with less than a full charge.

Voltage was 12.599 when I put it in. After charging the car overnight, it was 12.782 so DC-DC converter is charging it without issue and I have no reason to use an external charger.

I agree with the above instructions!

When I had to replace the battery, I used a 10mm socket and that is all.

I disconnected the positive terminal first, then the negative.

I removed the old battery and placed the new one in it's place.

I then connected the negative terminal first, then the positive!

Since the negative cable is grounded to the chassis, it is much safer to disconnect it from the battery first and connect it to the battery last.

This is important, so in case it isn't clear why:

If the negative terminal is connected while you are messing with the positive terminal, then if you accidentally touch your wrench to anything metal, your wrench will be shorting the battery and things will get exciting quickly. :shock:

On the other hand, if the negative cable is not connected, then there is nowhere you can short the positive terminal -- unless you drop your wrench across both terminals.

(Somewhat off topic, but once I accidentally dropped a wrench while working on my Jeep. Somehow it landed where it was shorting the starter solenoid, thus engaging the starter with the transmission in first gear. Luckily the parking brake was set, but it still was able to overcome this and slowly drive itself forward, partially crushing some stuff I had stored in front of it. The point being, stupid accidents happen, so don't rely on being lucky. I should have disconnected the battery first.)
