Replaced my battery with Odyssey 925

[MvM]

Last week, I bought myself a Odyssey 925 battery for my car to save some weight. And last night, I had the chance to install it.
I had to make some new rods to tie the battery in place, but it is very tight now.
However, I found out that the Yuasa Calcium battery that was installed already was pretty light. It weighed only 11.8 kg or 26 lbs on my scale.
I still have the original OEM battery which was a whopping 16.8 kg or 37 lbs.

But, nonethelesss, the Odyssey was even lighter. Although it is stated to be also 26 lbs, I found that it is actually a bit lighter at 10.4 kg or 22.9 lbs.
So, even if I did not same much in terms of weight, at least I saved some.

Here is a picture of the new Odyssey next to the battery it replaced.

I thought about doing this but I only drive my car every 2 or 3 weeks and I was concerned that it wouldn't hold a charge for long enough.

Another try after your bad 680-try (drainage)? :wink: -6 kg is not bad and they're said to live very long.

Here's how I mounted mine. Didn't have to change the battery cables.
Metal tabs bolt on both sides to hold battery from the top.

Lol,,, yuasa! nice battery

Yes, another try :smile: When I found a local dealer who was selling the Odyssey for a reasonable price, I could not resist.

Lol,,, yuasa! nice battery

Why the LoL?? Do you know the yuasa battery?

Here's a picture with my new Odyssey installed. Still want to shorten the rods even further.

You-ass-a thats' why the lol:wink:

Awsome so by removing spare tire, tool kit and lighter battery 75lbs saved?

To be honest, not quite.
OEM spare tire (1991-1996): - 13.3 kg - 29.4 lbs
OEM spare tire mount: -1.0 kg - 2.2 lbs
OEM Honda battery: -16.8 kg - 37.0 lbs
Odyssey battery: +10.4 kg + 22.9 lbs
Total weight savings: 20.7 kg - 45.6 lbs
Nice, but not quite yet 75 lbs.

The European NSX has a more extensive toolkit than the U.S. NSX. I did not remove that from the car, although I replaced some of the tools with more convenient stuff.
However, the aluminum jack and tire-wrench are 1.31 and 0.62 kg respectively, so you could save another 4.25 lbs there. But I consider these tools quite important so I did not remove them.
The rear towhook is not very heavy either, only 0.77 lbs (0.3 kg)

If you want, I can weigh the other parts of the toolkit also :smile:

LOoks good but why you didnt buy the Honda NSX-R battery?

Think the Honda batteries are the best in quality and durability,
so the one I have is 9 kg.
Thats freakin light.

I wonder about the Odyseey weight, it looks very small and should be lighter.
Is it 10.4 kg, really ?

I might have bought the NSX-R battery if I had thought of it I had been looking at the Dali site but found that the importer here is in Rotterdam as well, so I just stopped there and bougth one.
How much does the NSX-R battery cost anyway?

And yes, it is actually 10.4 kg. The battery actually states it is 11.8 kg but my scale told me it is even less.
Nowadays, I try to weigh every part I take of off my car or that I put on. I have found that often the stated weights are not what they are in reality.

 

[goldNSX]

Nice installation with the OEM holder stuff.

Honda NSX-R battery = Honda Civic IMA battery (don't know if the older one or current one) :wink: :wink: :wink:

Wow, I didn't know that. Thanks for the info?
Do you have the specifications for this battery. Is it also a dry-cell battery like the Odyssey.
Do you have the Honda OEM part-number for this battery?

If the Odyssey would fail, it might be nice to try this Honda battery instead.

Greetings thanks for the write, up I will take some notes. You can buy a Type-R battery from Procar(Detlef) they are in Germany. Time for carbon fiber rear bumper beams and other stuff to continue your pursuit of lightweight fighter jet Keep us posted

Couldn't that slide sideways? I know it's probably clamped down well, but I would feel safer by physically restricting its side movement.

 

[Big_D]

I think he is relying on friction to keep it from moving sideways. It might be a good idea to put a non-skid pad under the battery to increase the friction.:smile:

you're welcome :biggrin: :biggrin:

Can't tell you because i don't know ... but i'll dig that up :wink:

Do you have the Honda OEM part-number for this battery?

I don't have it, but i'll go ask for it.

next week i'll post here the finds i come up with :wink:

The thing with the 925 to remember.. is that it's a rock star. I've let is sit for months multiple times, and after a quick charge, boom, back on track. voltmeter pegged on the dial.

It's a good battery for stereo too. Deffinetly not the lightest, but keep in mind that JGTC race cars drive with a good battery (if I understand correctly) and there are lots of electronics in the NSX. The NA2s have Electric Power Steering.. That's not cheap! The power needs to come from somewhere and in my experience with the Oddysseys a couple of steps below the 925, it's not worth the trouble.

Thanks for the information.
I actually DID try the Odyssey 680 a couple of years ago, but it didn't last too long. The Clifford alarm in my car was such that the 680 would be drained in just three days That's the main reason I decided to give the 925 a try. We'll see how it will hold up.

Actually, the 925 is bolted down VERY tight.
And in principle, if the battery weighs LESS, its inertia to start moving around is also less compared to that of a 37 lbs battery :smile:
So I am not too worried about that. But I just might consider to put a few bolts in there as well. I still have the holes I needed to mount the original Dali mount that is necessary for the very small Odyssey 680.
