New Odyssey

[Animate]

I just installed the Odyssey 545. It gives a weight saving of approximately 20 lbs over the OEM battery. The car cranks over normally. I'm hoping it will work through our mild winter too, but failing that it's a quick switch back to stock.

I'm running out of inexpensive weight loss options. Looks like I'll have to get on the exercise bike....

WOW That is a little battery!!
What are the dimensions of it? I"m looking to replace my current battery but might need to get an Optima due to the goodies I have installed.

Length=7"
Width=3.5"
Height=5"

... And the most important statistic: 12 pounds.

If you do a search on batteries there have been some links to good articles and places to get these lightweight ones.

I'm very interested in a lighter battery. I pulled the stock battery out a month ago and hurt my back doing so. The stock battery is very heavy!

 

[4AU4LIFE]

Does it have the same CCA and amps as the OEM at the lighter weight?

 

[NSX Prime]

From what I see on the top, it only has 545cca. That would be fine down here in SoFLa though.

92NSX: I don't think so, The specs are here:

The one pictured is the PC545, but you can give up a little weight to get the larger PC680 or PC925, which are also available from Dali, along with the hold down hardware.

Check the links nsxtasy provided too...

DUH, guess I could've looked a little closer. Thanks for pointing that out.

From the specs it seems the 545 refers to hot cranking amps. CCA is 185.

Does anybody know the CCA for OEM?

Thanks for the links and info. Have to choose between this type or an Optima.

Mine is on the way!

 

[4AU4LIFE]

I do have a question pertaining to THIS thread. What do you do to take up the extra space in the box to compensate for the smaller battery?

 

[John McCain Racing]

I believe Dali Racing has mounts for all three of the Odyssey batteries and you remove the OEM battery box.

 

[4AU4LIFE]

Oh ok. So you totally remove the OEM box and install the brackets supplied w/battery, provided you get it from Dali?

 

[Animate]

I used the Dali mount. It requires drilling 4 holes in the plate where the OEM battery sits. I mounted mine a little differently than shown on Dali's site. It's further back and I've created two other holes in the bracket to avoid having to drill though the longitudinal battery tray support. This way reduces the chance of the fasteners being scraped from below.

The kit shipped with stainless Imperial sized fasteners. I'd like to keep it all metric so the stainless metric socket head cap screws are on order. The ones shown aren't stainless...

I have a question. The negative cable terminal has an unused 6mm stud attached. Is there supposed to be another ground strap here, or??

 

[4AU4LIFE]

Awesome pic dude. Thank you so much for posting.

A bit off topic but would losing that 40~50lbs by removing the spare tire/bracket and using lighter battery upset the balance of the car? Will taking out the engine cover neutralize this problem if it indeed upsets the balance?

 

[Animate]

Zuerst: I was wondering the same thing. When I go to the track I do take out the engine cover and tool kit. I'm also getting a new exhaust that saves about 25lb. That should even things out a bit.

I don't think it's enough to make a significant difference in balance. I've never noticed it, and I don't remove the engine cover or tools to compensate.

Looks Good!!

That is a good question. Although the engine cover doesn't weigh but a few pounds compared to the items up front. I never track my car so if it does upset the balance I would never know it.

 

[Animate]

Yes, as I understand it the term balance refers in part to the behaviour of the car at the limits of adhesion. For example whether the front tires lose grip before the rear (understeer) or the rear before the front (oversteer).

With regular street driving we are usually well below these limits, (unless the roads are wet/slippery) so the change in front/rear weight bias may not be noticed.

To keep perspective the 40lbs or so we are discussing pales in comparison with adding a couple of 200lb passengers and a trunk full of luggage in a 4 place sedan.
