Modified Nissan 350z

The first Nissan 350z rolled out of the factory over 15 years ago, can you believe it?

And while the Z33 has proven itself to be a very reliable car, it’s not unlikely your battery is on it’s last legs, if this isn’t the second time you’ve had to replace it.

Most mechanics will tell you, a car battery tends to last around 5 years before needing replacement. But for many 350z owners, it’s not something they consider replacing until it dies completely.

For this reason, many Nissan 350z batteries have managed to last over 10 years! You’ve gotta love that Nissan reliability!

The good news is, Nissan 350z battery replacements aren’t particularly expensive, or hard to find.

OEM Battery Specs

Rolling off the production line, your Nissan 350z’s battery specs were:

Manufacturer: Panasonic/Yuasa
Part Number: 80D23L
Cold cranking amps: 589 (also known as “cold cranking current”)
Group: 35
Size/Dimensions: 9.1″L x 6.9″W x 8.9″H (230mm L x 175mm W x 225mm H)
Type: Standard Flooded Lead-Acid
Weight: 36lbs (16.3kg)

In some cases, cars arrived onshore with damaged batteries, so if you have a battery manufactured in Mexico or somewhere else local to you, these specs will vary slightly.

Factory Replacement Battery

Replacing your battery is especially important if your car has been sitting over the winter while you wait for the sunshine to return.

But OEM 350z batteries were not exported along with the cars though, so buying a direct factory replacement battery for your Z from your Nissan Service Center is not possible.

Instead, depending on your region you’ll be sold a locally made equivalent, which have mixed reviews from owners.

The replacement Nissan 350z battery price from the dealer varies wildly depending on your region, but is usually between $120-$275.

We tow the line at Low Offset, when you’re replacing anything in your car, it’s the perfect time to upgrade.

350z Battery Upgrade

Have you ever been playing music while parked and hanging out with friends, and had the thought “hmm, how long can I do this for?” If you have an upgraded stereo system, this should be even more of a concern.

Accidentally leave the lights on for too long, or use your parking lights overnight, and you might not be able to get your 350z started again. That’s because it’s large 3.5L V6 engine requires a lot of power to turn over.

A battery with more cold cranking amps (CCA) is really going to help you out in winter if you live in a colder climate (note: if you’re really concerned about getting your car started in winter, remember to replace your 350z’s spark plugs too!)

From our point of view, the best battery for a Nissan 350z is a stronger replacement than the original; one with more cold cranking amps.

In addition to this, by spending that bit extra now, you’re also going to get a battery that lasts much longer than the cheaper alternatives, while being much lighter than your OEM battery.

The batteries in this article are in the same price range as a replacement from a Nissan dealership, so to us – it’s a fairly easy decision to buy an upgraded unit instead of a lower quality replacement unit.

When looking for a battery replacement for your Nissan 350z, it’s a great opportunity to get away from the heavy Standard Flooded Lead-Acid batteries.

For the most part, the best 350z battery doesn’t even need to be sold as lightweight – an absorbed glass mat or SpiralCell battery with more cold cranking amps than your OEM battery will save some weight.
