Battery 12 volt for R33 and R34 Nissan Skyline GT-R


This R33 GT-R had a pretty serious fuel system, two Bosch 044 pumps, two big filters, a surge tank, three relays. Optima yellow top battery

The R32 GT-R had the battery in the left front, in the R33 and then the R34 the battery was located in the trunk, above the fuel tank bulkhead.  It is left rear side, and there is a fuse/relay box that is close by/attached.

Like the R32 battery, the R33 and R34 batteries use a small terminal or JIS terminal.  You can find JIS terminal batteries in Japan easily, but in the US it is difficult and a little limiting. So terminal adapters are available, or you can swap terminals.  More information on batteries, terminals, and sizes that fit an R32.

R32, R33, and R34 use a JIS Pencil post battery terminal. 



Where is the battery?  It is here, trust us.

I used the old battery for four and a half years, so it worked well.  <br /> It feels like you're working hard.  <br /> <br /> The new battery can be purchased online.<br /> Even if you buy more batteries than those sold at SAB, you can buy them at half price or less!  <br /> <br /> It's cheap~ (^_^)v
The 60B has more reserve capacity than the 44B. JIS terminals. This also fits R32 GT-R

Ground cable does not have a lot of slack

SAE to JIS adapters. 
Group 51 battery with  SAE to JIS adapters works in an R33 GT-R



So what can you get in the US that works(R32 height, requires new battery rods)?

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.
