About to find out, sort of got lucky, it was marked manufactured in 07/2015 so they gave me a 20% discount, ended up being just a hair over $100 so I said screw it and bought it since my old bigger battery was leaking vapor at the postitive post and cording the crap out of my terminals.

It's been sitting so long it's not fully charged, so I'm charging it, assuming it cranks the car once fully charged fine. I'll be modifying the OEM battery tray to sit a lot lower but use the same mounting points at work Wednesday when I go back to work. (we got today and tomorrow off for Christmas) I brought a bathroom scale in the store with me , got some a couple odd looks, but soon as i picked up a battery and sat it on it, you could see it click in their heads. This was the lightest battery I could find between O'riley's, Advance, and Wal-mart. Napa was closed so I didn't get to see what they had as an option. The battery it's replacing was 29lb, and I have no idea what it's CCA rating was, but it was a couple inches longer and probably 3 inches wider. I'm betting it was 550 or so. I'll update soon as I find out if it will start the car well. It will stay on a trickle charger in the shop in my back yard so its small size doesn't worry me.


On a side note, anyone have any idea what kind of plastic the factory battery box is made out of? Wondering if I can cut material out of it, and use some sort of glue (or heat) that would "melt" it and enable me to "glue" it back as a smaller box that fits this battery. I'll be trying to modify that box reguardless as well as the OEM tray and hold down, so it will all mount lower, so it's not just lighter, but weight moving lower.

Your battery is low for it...OE is 525cca and 32 lbs. So, it might leave you stranded if you leave any sort of accessories on. I would say use OE specified and drop weight somewhere else. IMO relocate it to the trunk, if weight or space is an issue.

Yep, starts fine.



Just threw it in after it was close to fully charged (so it wasn't fully charged) to see if it would start. Typical DSM, it always takes 3 attemps to start to start. Turned over just fine first time, turned over exactly the same the 2nd and the third, and on the third as usual, it fired up. Going to change the oil in it tomorrow and actually install it for real and not just sit it there.

It should start the motor after a charge no problem, but I would recommend setting up a test for parasitic amperage drain. If you have anything drawing power it will kill it faster. Good thinking though, I saved 16 lbs with an optima d51r (same groups size) and never had a problem yet.

Well, new problem. It's too tall. And with the tray removed moves to much on the cross member for me to be ok with.

Sooo back to the parts store to get my core and money back...I'll just order the odyssey pc680.

why not just build a small box to hold it in place on the crossmember?

I run this battery and works great for me. I mount it under the passenger fender/bumper area. 310cca and only 15lbs. Pretty much the same size as a PC680 and has better CCA and has a slightly better reserve at 18ah vs 16ah.

here is a nice how to mount battery on cross member using stock holder. I am about to do this next weekend. instead of getting new battery, just a thought.

Push the battery back towards the firewall and get a better battery terminal post. Turn it sideways towards the engine and you should have plenty of room.

Meh, just returned it and got my core and money back. I'm going to just wait and get the better battery and make a tray for it at work from either stainless or aluminum....might just mod the OEM part though.

ECMLink upgrade from DSMLink is a bigger priority.
