Odyssey Pc925 Battery - R34 Gtr - Drained In 1 Week After Not Driving?

[Carbon 34]

Nice to know im not alone.

I was under the impression that Odyssey was one of the best batteries you could get?

It cost me a fortune.

Mine failed after a year with dead cell

If its not a grey import it should have a warranty ??grey market no warranty at all

a stuck relay can draw power

easy to put a meter on it and yank the fuses watching it for current draw

If you dont do a long drive weekly it will die ? buy a trickle charger designed for agm cell batteries

Or any battery will be dead , on GTR your current has to travel to the front and 925 is enough with big wiring , factory not so much

My agm battery with long drive weekly at speed , stereo etc off it becomes a bit sluggish if its cold out but still cranks decent , hot its is still strong for weeks even with massive draw of mutiple layers of security

Thats your opinion and i gave mine.

And just to clarify, yes i should have said that 33/34gtr its perfectly legal for wet cell in the boot, however as for other cars/skylines that have had a conversion done, it is not.

Wet cells are not legal unless vented outside the car , hydrogen gas is explosive the relay boxes a few mm away can spark , boom flash fire with acid spray , overcharge a wet cell , acid bath in the boot nice!!

always mount your battery with a layer of bulk rubber mat under it , vibrations kill batteries and skylines are rough riding on oz roads , clark rubber , 4 mm thick or so cost f all

I thought i would bump this thread,

my car has chewed through 2 battery's in the past 12 months.

The first one was a wet cell battery (car came with it) which died due to me not driving for 4 weeks when i first got the car, i put it on charge with a trickle charger, came back to it and there was acid in the boot, not to bad because i caught it just in time, but could have been everywhere. Have neutralized the acid, and prevented further rust, but i have to respray/clean up the boot and behind the rear passenger seats. Just light spotting where the acid dripped.

And it has done it just before Christmas now, how convenient, usually it takes about 2/3 weeks before it goes low and i will usually drive the car before that happens, all it took was 1 week to go flat, so either my alternator is not working 100% or there is another cause?

The new battery will be a Optima.

While i have my boot completely emptied to respray during Christmas holidays, is there any electrical work i should be doing?

I will be putting a new Nismo fuel pump in too, will the standard wiring be up to the job?

Look for the fuel pump direct feed rewire thread, it gets rid of the fuel pump speed controller and shows you how to upgrade your wiring to suit the pump and give it the juice it needs. Now, the battery. I have had 6 batteries in 6 years, and its mostly to do with discharge and not bieng able to bring it back. I had invested in a C-TEK battery cycling charger and i have never had an issue since. I went to an optima spiral cell sealed battery, on its side so i could get a bigger one in there. You pay a little more for a spiral or a calcium battery, but imho, its worth the outlay for piece of mind, and the warranty that comes with it. remember to invest in a cyclic trickle charger though, will do your battery wonders mate.

Thanks for the post mate, so the optima's are fine to have laying down, well thats handy to know. Thought i was gonna have to mount it differently because they are a large battery. I already have a C TEK charger, usually have it on, just surprised after a week my battery was flat.
