Replacement 12 Volt Battery for Nissan Skyline GT-R - R32

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(JIS 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.

S46B24R battery was in my Nismo R32 GT-R. It is a JIS terminal battery, and crosses over to the Toyota Prius here in the US. It weighs in at 28.78 lbs on our scale.

40B19R Lithium Iron

The best battery I have used recently for Nissan Skyline GT-R, that has JIS terminals, is reasonably priced, and seems to work best are the LiFePo4 or Lithium Iron batteries. I have been using them a few years now on a few different cars. I had one melt down on me, but I think that was more alternator failure, and some user error.  The cars starters actually sound a little different, like a little more pissed off, and the car seems to come to life faster. 


3.1 kg (6.8 lbs), but they honestly feel like they weigh nothing. 

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.

I would also like to suggest Optima Yellow Top D51 for the GTR BNR32. It fits perfect and you'll have extra space too since it is smaller.
