largest 12v battery in 2013 leaf?

Wed Oct 01, 2014 8:43 am

So I want to get a larger 12v lead acid battery to put in the leaf. Does anyone know what the largest stock size lead acid battery that would fit in the existing holder?

Why would you want to add a larger and heavier battery. Just use a better battery and you should have no issue a larger battery "size" is not necessarily batter.

I'm curious as to why you want to do this...

I am thinking of this mostly because I get the red battery symbol fairly often and I haven't been able to track down what is draining the battery. A few times I have seen about a 800 mA load on the battery with everything off, cycling to ready and off again often stops whatever it is, but without checking every time I shut the car off it could go dead on us. I am not sure what the heck it is, but it is intermittent and Nissan says it's not there. With a larger battery I wouldn't be as worried, heck it could likely handle a 800 mA load all day. The stock battery is sub par as far as batteries of similar size, sort of like the ecopia tires :) So I figured if I was going to replace it I might as well up size it as well. As far as weight if the extra 5 lbs of a larger more capable battery I think it is more than worth it. And going with something other than lead acid adds a lot more $ for the capacity.

My wife takes short trips all day, about 3-5 miles a hop, usually about 60 miles a day total and if she comes out to a dead car it will be bad for me and her job. So it is worth it to me to upgrade the battery.

In a deep-cycling situation, the type of battery may be more important than the size.

My choice for this application was the Sun-Xtender PVX-420T.

It's not any bigger, actually physically smaller than the stock battery. But since there is no free liquid electrolyte the amp-hour capacity is about the same despite the smaller size. The important aspect about the battery is that it is specifically designed for repeated deep cycling. Conventional 12V car batteries are not designed for deep cycling and will lose capacity when treated that way. Since the LEAF has no need of "cold cranking amps", this solar-storage battery seemed like an appropriate choice, as deep-cycle resiliency seems more important here given the vehicle's known tendency to draw excessive dark current under certain circumstances.

There were a couple of minor things I had to do to get it to fit:

I noticed you're still working with polymers.

Nubo, I completely agree about putting a true deep cycle in there as that seems to be more true cycling compared to a traditional ICE and that totally makes sense and AGM to boot :) I will look in to that. How is yours holding up?

It's doing well. I hooked up the charger to it recently, just to proactively give it a full cycle, but it was still over 12.5V.

I did have to purchase SAE-style posts to bolt onto the battery as it normally just comes with M6 bolts, iirc.

It might be worth checking this thread about replacing the lead acid battery with a lithium battery.

Trying to solve a phantom power drain with a larger battery is, at best, a band-aid approach. At worst it means wasting an expensive battery and still getting stranded. The best band-aid solution is a battery maintainer, used regularly.

I understand that sometimes you have to do what you have to do.
But the best fix is Nissan fixing the less than seven month old defective car.

If you have the option, I would try another dealer AND elevate to Nissan corporate even if you have to call them five times a week.

The usage pattern your wife has has been shown to put the poor Nissan 12V battery at substantial risk.
Could be phantom loads.
Could improper turn off.
Or both.

A good quality AGM might help, or if $ is not a concern, lithium.
But to fix the problem Nissan should troubleshoot till they find root cause and repair.
