no need for optimas for me. i tried them on my past hobby cars and imho, they are overrated, especially the yellow tops.

im just getting something cheap group35 i think it was, with cca 550 or better. it's not like nissan puts great batteries in their cars..they need to keep cost down.

I would go with optima or a XS Power. The one thing to remember is places like Walmart and Costco get the refurbished optima, not the new ones. We've run into a lot of problems with that up in Canada.

Home depot sells Exide batteries at the store now. Not sure what group size the 370z takes but picked one (24fx) up for my G earlier this year for $100+tax. 40 month replacement warranty.

We'll see how easily it is to exchange the battery around month 36.

I love my optima... :)

I'd stick with what's correct for the car. Looks like Amazon has a decent price on them.

I'm on Amazon and there's a note about checking hood clearance and possibly needing a mounting kit.
So does it fit??? Should I order that one? Anyone else have this battery/part number?

Thanks!

The costco near me only sold interstate batteries brand, $77, but the battery was physically larger then the OEM.

i took it to the dealership on Tuesday. They charged me $99 for the OEM battery. 24 mo replacement , 6 year prorate

I also got a Check Engine Light after starting the car on the dying battery. Hopefully that is related and will go away after replacing the battery?

Removing the battery to replace it will clear the CEL

Do you have a way to pull the code?

When I ordered my optima online, it came with packing material, it was hard cushion material, I cut a piece of that and sat the battery on top of that, then used the 2 oem hook thingies to lock it in place.. It worked like a charm.

Thanks for the PM.

Put mine in todayAttachment 110785
Factory battery didn't fail; just noticed it getting weaker on cold mornings & just over 5yrs. Old

Did you need to do anything special to make it fit?

I could have used supplied spacer, that snaps on bottom of battery & raises it up about an inch; but liked the way it sit lower and flat in the tray.
I turned around hold down strap (notice arrow facing rear) and put the short J bolt in the lowest hole / then used a spacer (chrome 1/4 inch drive socket) over threads of longer front J bolt and put nut down against it. Holds good & weight of battery is about 1" lower.
Don't over tighten.
Width of battery is a tad narrower/ so when I get back to work, gonna make a rubberized spacer to go between top of battery & brace.....could leave as is; but gonna pay attention to detail.
720cca 160$ (including tax) works like a charm.

Btw.. Had to re-time my windows. :)
