hey

iv done a quick search n havent found my answer

simply: im looking for a battery for my R34 Gtt...

what CCA am i looking for?

i have a pretty demanding sound system

thanx

Depends on your end goal, I have a 1200 Odessy, the CCA is worthless here in OZ, its a value based upon cold cranking amps, only good to know when it s below freezing. but more is better.

I'm not sure why but oz has outdated batteries floating around in cars, the kind that still take water? until moving here I havent seen one for at least 10 years. crap!!!, the odessey batteries are dry and can be mounted upside down it you wanted too?

http://www.odysseybatteries.com/battery/pc1200series.htm

PC 1200 Specs:

  • 1200 cranking amps for 5 seconds
  • 1090 cranking amps for 10 seconds
  • 900 cranking amps for 20 seconds
  • 825 cranking amps for 30 seconds
  • Short circuit current over 2600A
  • 44 amp hours
  • 78 minute reserve capacity with 25amp load
  • CCA - 550 (Is this important?)

But I have had better luck with these batteries,

had the same battery for 11 years in my RX7 and VR4 with massive sound systems in them,, never failed

the odessey I have has failed once , had a dead cell when it was in my crappo commo with a big system. think it might have been a alternator failure that caused it.

these are best as long as you dont sit in the park for hours pounding bass, if so then you need to look at a deepcycle maybe, but then you need to drive a lot to charge it back up?????

but these batteries can be expensive, 200 or more but well worth it ,, and dont mix gold connections to lead posts if you can help it, corrosion is faster then normal once scratched. I chopped off the old nissan connections and put in some decent ones. and run another ground wire to the bracket of the alternator or engine and one thick one to the fender, not a painted part, this will improve power and helps misfires too.

hope this helps

If you are also intrested a optima blue top. battery suited for the marine enviroment is also a great buy.. For $345 you get 850cca but it actualy is 1250cca and 55 ah rated also a bit more at 66ah.. iv just got one and im running a 2 1000w rms subs with 4 200w rms speakers and iv left it on mid mid vloume for about 90 to 100 min and it still started the car my experences

Blue tops, they tend to get short charged if you dont drive for a while after discharge.. hence the boat battery, boats get put on a charger at night to top them up. drive a short distance all the time and they will fail. (they get a memory of short charging and wont come up over 10volts in the end)

great for a parked car annoying the oldies for hours on end ..lol

there is a few other brands but they cost a bit more for virtually the same thing.

    • Ah right. Maybe my rb just loves chewing through batteries lol.
    • On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
    • 12.8 for a great condition, fully charged battery. If the battery will only ever properly charge to about 12.2V, the battery is well worn, and will be dead soon. When I say properly charge, I mean disconnect it from the car, charge it to its max, and then put your multimeter on it, and see what it reads about an hour later. Dieing batteries will hold a higher "surface charge", but the minutest load, even from just a multimeter (which in the scheme of things is considered totally irrelevant, especially at this level) will be enough over an hour to make the surface charge disappear.   I spend wayyy too much time analysing battery voltages for customers when they whinge that our equipment (telematics device) is causing their battery to drain all the time. Nearly every case I can call it within about 2 months of when the battery will be completely dead. Our bigger customers don't even debate it with me any more ha ha ha. A battery at 12.4 to 12.6 I'd still be happy enough with. However, there's a lot of things that can cause a parasitic draw in a car, first of which is alarms and immobilisers. To start checking, put your multimeter into amps, (and then connect it properly) and measure your power draw with everything off. Typical car battery is about 40aH. Realistically, you'll get about half this before the car won't start. So a 100mA power drain will see you pretty much near unstartable in 8 days.
    • Car should sit at 12.2 or more, maybe 12.6 or 12.7 when fully charged and happy. If there is a decent enough parasitic load then it will certainly go lower than 12.2 with time. You can't beat physics.
    • Ok guess I can rule out the battery, probably even the starter and alternator (maybe) as well. I'm gonna clean those leads and see what happens if it's still shit I might take it to an auto electrician. Unless the immobiliser is that f**king heavy, but it shouldn't be.  If I start the car every day, starts up perfectly never an issue. Isn't 12v low, shouldn't it be around 12.5v?
