Is everybody using just a standard battery? The shop put in an old asz battery and charged me for a new one. It was sitting at 12.9 or so volt from day one. after a few months, it's at 12.3v with a warning light coming on from my turbo timer (just the other day, It didn't even have enough juice to crank over and had to charge it).

is everybody using just a standard battery? any benefits of getting a deep cycled battery? i've read some peeps having longevity issues with optima.

 

good old Sam's club battery, had to buy one on the road back from Zdays a couple of years ago, no issues.

 

I use the Optima Red...there is no issues with it.

 

I have a regular Autozone Battery and a 1500 watt stereo system

 

I've tried Optima yellow top, Odyssey light weight, Optima red top, and regular old NAPA off the shelf. The last was the cheapest and has done well. Both yellow top and Odyssey did not last long. The red top has done well in my other cars.

If I had to recommend - I'd get a cheap, heavy (standard) battery.

 

I'm willing to bet the cause of your drain is an improperly wired wideband O2 sensor. If wired wrong, its heating the element all the time, and thus killing your battery. I had the same problem with my braille battery (which was a whole lot easier to kill anyway) until I rewired it.

 

that's 2 'Ok's for the optima red top.. might have to try it out

definitely not. My battery was sitting at 12.9v when it was put in. I'm positive it was a used pos. New batteries should be around 15v.

 

Ah my bad, I spaced on that line in your original post.

I was just saying that cause I know a lot of people who've had mysterious battery drains after going FI, and the cause was improperly wired wb's

 

I have an Optima red top, been happy with it. Let me know if you need the part number since we need the one with the reverse polls.

Good luck,

NAPA or just OEM.

I have the largest cranking amp NAPA battery Sharif could fit into the car. Not sure of the part number, if interested I could look further.

 

I think it's the INSSC34R.

red top is apparently 800 cranking amp.. should be plenty. dunno exactly what the stock numbers are but it's a lot less, i believe.

anybody know where I can pick this up? I'm think superautobacs might carry them.

 

I'd go with a stock one, mine has lasted 5 years and still going strong. Of course I have had the same luck with NAPA batteries in the past with my other cars.

 

don't believe what the box on your pyramid amp tells you...

 

OEM battery, even with a stereo, there is zero need for anything else - and they are inexpensive

 

If you are asking about the Red Top....Autozone is where I picked mine up.

 

don't be an ignorant a-hole.. wow look who's talking ****.. the guy with a full JL Audio system.. you just lost all credibility

 

Can't go wrong with optima, don't know if it is really worth the extra money though.

 

IMO, don't skimp on a battery. It is a maintenance issue that YOU have control of, unlike some you'd rather be in control of but Nissan tries to do so.

 

lol don't be jealous...1 sub and two amps dont quite make it a FULL Jl system though...

so lets see pics of your 1500 watt system...

 

keep looking.. you will see it.. they are all around.. so what do you have for components? probably something generic and weak like your choice of JL Sub and Amps
