Interest In A 12V Battery Upgrade Kit??

Hi Guys,

The 12v Battery on my 2013 S died suddenly earlier this week, and I tried a number of alternatives to the weird size battery Nissan put in the car. Eventually I settled on a slightly larger (Group 56) battery. It fits in the same spot as the OEM battery (there is a lot of room) but it does require a custom hold down that I'm making. I was thinking about offering these as kits for other people. I know some people don't feel the 12v battery is charged enough and upgrading the the larger Group 56 battery will help with that some. As well as allowing you to buy a replacement battery anywhere at any time instead of having to find the more rare 51R size. (And the Group 56 is about 30% cheaper).

Electrically it is identical, just has a larger capacity.

Thoughts?

Joey

I posted a similar swap. I found the space is the same as the Nissan Rogue so I swapped mine out for that. The details are in this thread

So will just the Rogue hold-down work with the Leaf tray?

The hold down would work with the Leaf tray, but the 34N won't fit in the Leaf tray

I'm surprised you describe the 51R as rare. Here in the Portland/Vancouver area, I've found it at every local store that carries car batteries. It's in millions of Hondas, and probably other makes as well.

OTOH, if you claim it is small and overpriced, I'll definitely agree with that!

Yeah, they aren't super rare, I'm actually down in Corvallis and I had a few options, but not everybody had it. And, I couldn't get the Optima without ordering it and that's what I really wanted.

@BrockWI - nice write-up. Thanks for pointing me to it.

The Size 56 battery has the posts much closer to the sides than the Rogue battery, did you have any trouble with the bundle of wires. On mine, the battery is now pushing the bundle of cables out of the way a little. But it's just a smidge. I was going to put a small pad between the battery and the bundle so that neither one wears through the other, but I doubt that would even be a problem. Just trying to be sure.

It was really a pretty simple swap , the neg lead is a bit shorter, but not so much to cause any issue.

Let me try again. Group 56 battery, in Leaf tray, with Rogue hold-down. Will those work together? The hold-down in mine looks pretty universal. I suspect a generic adjustable one would also fit.

It may... The 56 is still a relatively narrow battery (6 1/8") whereas most of the batteries are approx 7". So a universal hold down may work. I ordered a few different hold downs to try out. I want to find the best fit. I also ordered some acid neutralizing absorbing mat since the tray isn't quite big enough.
