Anybody know the specs on the OEM sedan battery? I know it's an 80D26L, but i find CCA specs anywhere from 445 to 582, and Ah from 40 to 55. I'm not running any ICE other than a couple extra gauges, just want a lighter replacement battery...but I need to know the OE specs first so I know which Optima/Odyssey to get. Thanks.

Check the manual. I'm almost positive it's in there.

this whole thread is about which optima battery will fit. You only have two choices in yellow tops so just do the reading.

Just installed my D35 last week, works great, thanks everyone who helped me out!!

I guess I should have been a bit more specific; I'm relocating my battery to the trunk, so I'm not concerned about fitment. I just want the lightest battery possible within OEM specs. At this point I'm considering running two Optima 6v batteries in series for better wieght distribution.

After reading the threads regarding Optima batteries, I am still not clear if my Optima D34/78 will fit in my G35 coupe. Want to intall a system and already have this battery from my previous car. Do I need an extender? If so, does anyone know where i can purchase one?

The easiest way to see if it will fit is to pull out the battery that is there now and see if the Optoma that you already have will fit.

They have this new high-tech device called a ruler or tape measure now. I think they teach operation at most community colleges. (We need a smiley for smart-****! My pain meds are really rocking tonight!)

I am new to this forum and don't need smart remarks. If you don't have anything to add that is helpful then please don't post at all.

If you don`t need smart remarks, don`t ask stupid questions. Do you not understand the concept of smilies to indicate jokes? Perhaps the comment telling you to test fit the battery was more illuminating for your mystery. Personally, I would rather move a ruler than a battery, but, to each his own. Grow up. If you are so easily offended, you will have a rough time in life.

please step up the intelligence quotient

Just an update. I finally got around to installing it. On their website, they mention that a bracket is included. Make sure you get it. Or else the battery is too small for the hold downs to work. Unless you rig a big spacer or something. But fits fine and works well.

Good point. I was not able to use the hold-down with my current battery.

For reference. See in the notes below. The bracket actually comes with a large bracket with one small add on at the bottom. I tried using both but it was too tall. Remove the small one and it's perfect. When I first received the battery, it didn't come with one so I had to ask for it after the fact. Might save time to make sure you ask for the bracket specifically when ordering.
