Replacement 12V Batteries for Nissan Skyline GT-R - R32

R32 GT-R Battery on a Battery Tender
When cars sit, the battery has a tendency to go flat or dead. Accessories within the car pull a small load on the battery, and eventually there is no more power. If you let it sit for long enough, you kill the 12 volt battery.

The R32 Nissan Skyline GT-R has a pretty small 12V battery. It is also a fairly easy car to start. Its not some huge compression big block. its a short stroke inline 6 that doesn't need a whole bunch of CCA to start.

The OEM battery is small (approx 7 1/4 wide, 7 3/4 inches tall, and 5 inches thick), and they have Japanese sized terminals. Which means they are smaller. Not as thick as American terminals. Nothing else meant by those statements at all. Keep it clean.


When my R32 GT-R arrived, the battery was flat. It was one of the first things I was expecting to replace. However, I had a Battery Tender at home, plugged it in, and the car has been starting strong since. (2+ years). I highly recommend keeping a car you don't daily drive on a tender.

So what can you get in the US that works?




An Odyssey PC680.  Small battery. They are more for motorsports type applications. They really need to be left on a tender. They don't have a lot of reserve capacity. Once you kill them once, I've never been able to bring them back to life.  Still loses about 5 lbs compared to a stock size battery. Plus there are correct terminals available. Prices aren't horrible.

These guys have the Japanese JIS terminals that screw into an Odyssey battery.

This will last longer, but the car will gain some weight on the nose.  About an 11 lb gain.

Can I Run Different Sized Tires on My Nissan Skyline GT-R?

Can I Run Different Sized Tires on My Nissan Skyline GT-R?

A: A Nissan Skyline GT-R came with the same sized wheel and tire front to rear.

  Stock wheels and tire sizes
R32                 16 x 8 +30  205/50/16
R32 Vspec      17 x 8 +30 225/50/17
R32 Vspec II  17 x 8 +30 245/45/17

R33  17 x 9 +30  245/45/17

R34   18 x9 +30 245/40/18


The ATTESA, or all wheel drive system in a GT-R, uses inputs from the throttle, from the G-sensor, and from the ABS/wheel speed sensors to lock up the center differential.  If the wheel heights are different, they rotate at different speeds. The ATTESA/ABS ECU sees this as slippage. This causes lockup of the center diff. That constant lockup can lead to heat, slippage, and burning out the transfer case clutch pack.

ATTESA System overview technical document

So, can you do it?  The answer I like to give people is - NO.  The reason is because I don't want them to do something wrong, and screw up their transfer case or ATTESA system, and blame it on me.

The real answer is, if the overall heights/diameters are similar enough, you can get away with different sized front and rear wheels, tires, etc.

There are no specs in the R32 Service manual, but the R35 service manual says

Diameter difference front/rear
0-4 mm STOCK
4-8 mm OK
8mm- and greater NO GOOD

I have seen worn tires throw an ATTESA code. You could get a code running tire pressures way wacky ie 40 psi in 3 tires, and 20 psi in one.

Most often people try and do some kind of staggered setup, don't do the calculations before they purchase tires, and now end up with a 2wd Nissan Skyline GT-R.  Which may sound like fun, until you want/need the all wheel drive.   So always check the diameters, make sure before you buy anything.  The safe way is stay square. Lets you rotate the wheels and tires around the car. Great for real cars that run on the race track, and even street car guys that run some miles.
