Odyssey battery install - 21 pounds weight savings

[GT500wantabe]

I installed an Odyssey PC680MJT for a 21# weight savings. I did have to remove the factory battery holder which is part of the savings. Did not see a convenient way with the holder in place. After about 2 weeks no problem starting. I'm sure if my engine had to grind for any length of time I might have a problem. Even after opening the door and doing an HPT flash it still started. And I can't tell that it cranks any slower than the factory battery. This is the PC680 with the metal jacket for auto use.

Don't know why the threaded rod appears to look at an angle. I went back out and they are perfectly straight.

Nice! I hope it holds up. I used that same battery in an E46 M3 without issue.

Is that the same battery as this one?

Can you post a pic from directly above the battery with the red terminal cover off the post?

TIA

The battery you show is not the same. Mine is for automotive with a metal case around it. You want PC680MJT although mine only shows the PC680 on the top.

Ok I found the one you are using:

So for you to install that battery you pulled the stock bat holder? Do you reuse the factory holddown to secure the Odyssey bat?

Any updates as to performance so far? Still no issues starting and powering the Shelby electronics?

I notice your battery is sitting directly on the factory metal battery stand. I would recommend you put the new battery on a plastic battery tray. It will keep the battery from discharging power to the metal stand and corroding it.

Most Honda cars have a tray similar to the one pictured above and should work great with that Odyssey battery.

That's my battery. No issues so far. As long as it starts the engine then the alternator keeps all the electronics going just fine. I wouldn't plan on sitting very long with headlights on, etc. with engine off.

Probably a good idea to put some kind of plastic tray under the battery. I did not think of the corrosion possibility. But yes, I did remove the factory battery mount. Just didn't see a good way to use it. The two factory mount threaded holes were just the right distance apart. Maybe Odyssey has some kind of plastic mount that would fit this battery better than a Honda mount.

I ordered some 6mm x 1.0 threaded rod from Zoro along with buying 1/8" aluminum flat from Home Depot. 3/16" thick would have been better. I painted it black. I think black looked better. The threaded rod is zinc coated Zoro part number G3704854.
