Battery Replacement & Relocation

Tunes67 · Post by **Tunes67** » March 28th, 2006, 4:58 pm

Hey guys.. I have decided to relocate the battery in my GS to the rear of the car.. now I have looked at a lot of threads on this and seen a lot of pics of how people have done this. I wont have any issues with the relocating.. however.. A friend got one of these batteries for his MR2 and loves it.. just wondering if anyone else has tried them out.

Now if you havent used one.. or seen in person one used.. that wont help me much. But I am just wondering about their reliability.. the size and power seem excellent as well as the weight.

Holly crap. I'll get one for sure. You better jump on it before I do. 680 CC, that is more than what is on my car now (550 cc) and it works fine. Thanks for the info, man....

Thats not an auction.. its a Buy it now.. there are plenty of them.. And likely unless someone can tell me specifically why I shouldnt.. I will be getting one on the 11th.

The part I really like about them is that they are a drycell.. meaning you can mount them any way you want except upside down.. which means.. if you lay it flat.. its only slightly more than 3 inches tall.. which means.. it will fit in the spare tire well without modification...

Wish I could help more on this topic Tunes & hope this post adds something, cuz bottom line is, I don't have any direct exp. w/the Odyssey. Attempted some Web research last yr but wasn't very successful so finally installed an engine-bay-mounted Optima YellowTop D51R - 10 lbs lighter and ~40% smaller footprint than stock but still 11 lbs heavier and ~40% larger than the Odyssey PC680MJ. YellowTop specs seem somewhat better than the Odyssey altho I'm not sure about the Odyssey Cold Cranking Amps (CCA) rating, the way they list cranking amps, it's not clear that 680, etc. =CCA. I've never found any car owner reviews on the Odyssey. They do seem well accepted on motorcycle BB's. Here's the comparative mftr specs:

Optima YellowTop D51R

Weight: 26 lbs.
Cold Cranking Amps: 32°F 625, 0° 500
Length X Width X Height: 9.31" X 5.06" X 8.94"
Capacity Ampere Hours @ 20 Hr Rate: 41
Reserve Capacity: 70
Internal Resistance (ohms): .0046
Post Type: SAE Post
Warranty: 12 months free replacement, remaining 12 months prorated

Odyssey PC 680MJ:

680 cranking amps for 5 seconds
595 cranking amps for 10 seconds
525 cranking amps for 20 seconds
Short circuit current over 1800A
17 amp hours
25 minute reserve capacity with 25amp load
Female brass terminal w/M6 SS bolt
With metal jacket
Length 7.27"
Width 3.12"
Height 6.67"
Weight 15.4 lb
2 year full warranty

I'll be interested in the experiences/opinions others might post here. Odyssey's small size and your thread makes it worth considering it again. You plan to lay the batt down flat in the spare tire well and I want to relocate mine to a standing position in the pass-side rear footwell - but my bolt-in floor bar doesn't leave enough space even for the Optima D51R. The Odyssey would fit tho + save another 11 lbs. My MX-3's YellowTop could go into the old MX-6 which needs a batt soon anyway.

Q. How long has your friend been using the Odyssey and has it had to survive any stretches of cold weather?

My friend has only had his Odyssey for a couple of months now.. and here in Western Washington.. we dont get cold weather as the rest of the world understands it

I agree with you on the CCA. I was assuming that the 680 was CA since they didnt put down CCA specifically. Though typically CCA is usually about 100 A less than CA. So still.. a 580 CCA for my needs should be enough I would think.

It seems a bit small for loaded times. I'd do the Millenia Alt with it to make sure you don't run it dry when you have the radio and AC on and then try to roll a window or two up.

That is totally unfounded technically, but just from its miniature size...

My $130 red top optima has like 800 some cc

Tunes67 · Post by **Tunes67** » March 28th, 2006, 10:09 pm

Was planning on running the millenia alt as well.. but I also dont have AC either

The thing that is the most attractive to me is its small size.. I'll follow up in this thread when I get it and get it installed. Cheers

I have that battery

I didn't relocate it to the rear..

I'm in australia & am putting the straight neck ze in with this battery next to it..

done all the measurements, should fit ..

It's only 78mm thick, or just over 3 inches

Had it in for about a month, no problems, ze will hopefully be in in the next month.......

Odysseys are great batteries. Also look at Orbital. I got mine for $85 shipped from this guy: http://cgi.ebay.com/ebaymotors/ORB75DT- ... dZViewItem

The Orbital are built like a tank compared to the Optimas, and they're still sealed acid.

Tunes67 · Post by **Tunes67** » March 31st, 2006, 12:22 pm

I have heard Orbital batteries are really good.. but I want the Odyssey for size & weight.. I am glad to hear that there are a couple of folks that have had some experience with them

My friend with the MR2 has been trying to sell me on these batteries for a while now.. but since he has one.. I had to consider his opinion to be a bit biased

Besides.. if you buy something that sucks and its expensive and everyone told you not too.. you arent likely to admit that it sucked

LOL

Check out the specs at the Summit site. Lower CCA rating than I woulda thought for the ODY-PC680MJ ...
http://store.summitracing.com/partdetai ... toview=sku

ODY-PC680MJ
Cranking Amps at 0 Degrees F: 265 amps
Cranking Amps at 32 Degrees F: 370 amps
Reserve Capacity: 24 minutes

Might be too lightwt. an app for my climate. A straight winter month with constant daytime temps at or below freezing are typical here and anywhere from the single digits to mid 20's F @ night.

Heaviest duty Odyssey seems to be the

ODY-PC925
Cranking Amps at 0 Degrees F: 380 amps
Cranking Amps at 32 Degrees F: 500 amps
Reserve Capacity: 52 minutes
Length (in): 6.625 in.
Width (in): 7.000 in.
Height (in): 5.000 in.

would a bad alternator harm a red top battery? shorten it's life? would the damage if any, be fixed as soon as a new alternator is installed.
