New battery recommendation for my 2015 Nissan Leaf

Fri May 22, 2020 6:37 pm

My Nissan Leaf battery has died after more than a month of being left in the garage because of Covid-19. I now realize that I needed to disconnect the 12 V battery which I will be doing in the future.
I tried to start the car and run it for 10 minutes near the house recently. However as soon as I got back into the garage, the car would not let me shut it down saying that I needed to press the brake pedal even when I had it pressed down. I could not shut it down no matter what I tried. It even gave me a T/M system malfunction error. Now the battery I believe has no charge in it.

Can you suggest which 12V battery I could buy and replace the current one with.
I read in another post that Optima Yellow Top 51R might be a good replacement. Is this true? Are there any other options in the group size 51R range.
Thanks in advance!

I'll merge this with one of the 12 volt battery topics later tonight.

For longer storage life, a size 51R AGM battery is best, but a Yellow Top or similar battery will also be an improvement. You will still want to either disconnect it or use a maintainer for long storage.

Yellow Top Optima is a true AGM deep cycle battery (Optima was one of original AGM type batteries available for automotive use) and a good choice. I replaced the OEM batteries in my 2011 and 2015 with Optima Yellow Tops and will replace the battery in my 2019 with one at the first sign of weakness. I use Optima Red Tops in other vehicles. 51R is the correct group size for the Leaf.

Last time I looked (many years ago) the Yellow Top was called something like a "hybrid" battery, meaning more like a marine type. Either they changed it or I misremembered. Thanks.

It is (always has been) an AGM battery designed for deep cycle use, but it can also deliver high short-duration currents so it is OK for motor starting. The "hybrid" description probably came from that dual motor starting and deep cycle capability (this also makes it a good choice for marine use).

Did you leave the car plugged in (after charging complete) while it was parked? Did you leave something connected to the OBDII port (such as a Bluetooth adapter for Leaf Spy)? Either of these actions will keep the computer modules in the car active which increases current draw from the 12-volt battery. The car will periodically turn on the DC-DC converter to charge the 12-volt battery when parked for extended time, but anything that keeps the control modules from going into deep sleep may interfere with that periodic charging. I routinely park at either the airport or my office for extended time without issue except for the one time I forgot to unplug the Bluetooth adapter from the OBDII port.

Although I like the Yellow Top, the Bosch Platinum is another AGM battery that is available in 51R size. I strongly recommend an AGM battery because they typically have lower internal resistance so they recharge quickly from the DC-DC converter.

It should be noted, though, that a lot of cheap batteries are now called "AGM." All they have to do is put some fiberglass in with the electrolyte and they can call it that, even if the performance is no better than a typical flooded cell starting battery.

Try taking it to any national chain auto parts store they will charge it for free.
I completely killed the battery and left it dead for months in my tractor at least 2 times in the last 3 years. Charged it with a dumb battery charger and it works fine.
When the battery in mine dies it's final death I will likely replace it with a deep cycle marine and relocate it to the back of the car.

I bought my replacement battery yesterday and the best price I could find was at Advance Auto because they have a 25% discount code running right now "MEM20" (online only). I recommend AGM if only because they cause less corrosion to the battery terminals and tray.
Nowhere on the internet could I find a 51R AGM battery for much under $200. I think you can take in the old battery to the local store for your $22 core charge refund. https://shop.advanceautoparts.com/o/adv ... veal=13925

Optima was the best battery available about 20 years ago. I'm told they offshored the manufacturing process and now I can't recommend them. I had a couple yellow tops that failed young. Project Farm test: https://www.youtube.com/watch?v=h7rTcBanpMk&t=18s
It shows Optima is not worth the extra money for sure.

I did not leave it plugged in nor did I have any OBDII ports connected. However I did not drive the leaf for over a month and did not disconnect the 12V battery either which in hinsight I should have done.

When you do disconnect the battery where do you guys store the disconnected battery. Is it safe to store in cars trunk?
When you disconnect the car battery how do you make sure that you do not lose the settings (presets/clock) in the car.
