12 Volt Battery Replacement for R33 and R34
 |
| 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.
 |
| The ground wire is a little stretched, but it works. This battery has JIS terminals |
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.

AGM Group 47 sized battery
This battery has SAE sized terminals, which are larger than the normal R32/R33/R34 JIS sized terminals. This particular car has SAE sized terminals. This also requires a replacement battery tie down rod. The OEM R34 rod is about 7 1/2 inches long. In this car, we used a 9 inch rod.
R34 OEM j hook bolt top is about 7 3/4 inches long. OEM R32 GT-R bolt is about 7 1/4. You need about a 9 inch j hook to make the install easier.
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.
