Odyssey Battery inside Antique Auto Battery
I have a 1969 dated Antique Auto Battery with the internal AGM battery apparently past its life. I have removed the battery from the restoration case but finding what it specifically is has been a challenge. There are no part numbers on the battery. An old post I read indicated that these were made by Odyssey specifically for Antique Auto Battery and not available to the general public. As this was an old post and referenced a C1, I was hoping that was not the case today. On the Odyssey site I found one battery that looked very close (ODS-AGM30L) but it appears the + and - terminals are reversed from what I need. Can anyone identify this battery? W-168mm L-170mm H-125mm. With the terminals away from you the + is on the right. Pic attached.

FWIW: A current correctly sized DELCO service replacement with proper side/top caps would only generate a 5 point Originality deduction.

Re: Odyssey Battery inside Antique Auto Battery
I appreciate your reply and I am aware of recent changes in the judging points for batteries, but since I have this case I would like to find a battery that would work. Also, the current Delco service replacements are changing as well. Last week I went to buy a Delco 24PG for a mid-year that was available last year and it has been discontinued and replaced with Delco 24GHR that has no top caps. Just last week O'Reilly's showed the 24PG on their site and I called they told me it was discontinued. They did not even know the replacement number, I got that from another store. Plus, if you look up Delco 24GHR the picture you will see shows top caps but the actual battery maintenance free, flat and sealed on top.Comment

My guess is, recent change to Standard Deduction Guideline was to address declining availability of "restoration" batteries. Made service replacement option a more viable choice for owners.
Your comments, re caps for example, would indicate NJC might want to revisit this recent change for modification.
Why penalize owners for marketplace options no longer available?

Re: Odyssey Battery inside Antique Auto Battery
Thanks David, appreciate that. I see 330 CCA, less than half a full size battery. A close in size 400 CCA version they list appears to only be only offered in right positive. I have no way of knowing the CCA of the one Antique Battery used. It seems the part numbers change frequently on the odysseybattery.com site. For the one you found in left positive they are showing ODS-AGM28MJ (PC925LMJ) - https://www.odysseybattery.com/produ...tery-pc925lmj/
I also noted that if you check other vendors they often show a picture of a right positive battery when you put in the number that should be left positive. Now that it is Monday I will email Odyssey and see what they say. I would like to know if there was an actual battery they made exclusively for Antique Auto Battery as well.Comment

Re: Odyssey Battery inside Antique Auto Battery
As long as it is an OEM Delco battery, I don't think to top caps matter to get the same deduction as before.Big Tanks In the High Mountains of New MexicoComment

Re: Odyssey Battery inside Antique Auto Battery
I have a sixteen year old Antique Auto Battery case which looks an awfully lot like the original DC-12 batteries GM used in 1966. I've just recently replaced the smallish AGM inside with an XS Power battery, their model number D975. This battery is rated at 43 Ah, a little over 600 cranking amps and something like 505-515 cold cranking amps. Every situation is going to be a little different (as to original model AC Delco we are talking about and how the individual feels about the end result) and my solution may not please everyone or the purist who's looking for judging points. Having said that and given that my car was judged Bowtie back in 1999, I believe, and hence is not permitted to be judged any longer my main concern was keeping the old case being that it has screw in caps with yellow printing "AC Delco" wording I really desired to keep that case. Therefore, the purist may not want to read further.
For those still with me, I cut the bottom out of the DC-12 case keeping the total height of something like nine inches in tact. The model D975 is rather a tight fit but the advantage is that it has pretty good cranking amps. The D975 measures 7.83 " long, 5.3" high, and the actual width escapes my 80 year old memory, but it does fit inside the case rather easily with about 1/2" to spare so must measure about 5 7/8" deep. Once the new battery is inside a sheet of aluminum, plexiglass or plywood can serve as a new bottom, which is not visible given the tightness of the battery tray. To some of the purists out their the only down side is that, in my case, a rectangular opening must be cut in the end of the battery closest to the engine. To me this was a small sacrifice to make and is, in any event, pretty well hidden by the exhaust heat shield. In my case the lookalike DC-12 had a long (about eight inches) ground cable and a short (about 5.5") positive cable. Thus, in order to connect that cable a hole needs to be cut someplace near that positive connection. My opening measures about 1 1/2 inches by 2 7/16" which is sufficient to get a 1/4 inch drive ratchet and 10 mm socket inside. The D975 has the terminals reversed from the DC-12, but this, in itself, is not a disadvantage.........in my case.
Judges seem to notice everything but to the average C2 owner the rectangular opening in the end of the lookalike DC-12 would never likely be noticed.

Re: Odyssey Battery inside Antique Auto Battery
Greetings,
Looks as though there hasn't been much interest as regards my comment from yesterday but, having realized my error as to dimensions of a D975 from XS Power, thought I'd post with a correction. The width or depth of these batteries should be given as 5.3" and the height 6.67". The length is, as I said, 7.83". Some might question, upon reading this, how a battery this "tall" would fit inside a DC-12 case. To clarify, I cut an opening in the bottom of the case along the manufactured joints between the sides and the bottom. A new plate screwed to the bottom of the sides then gains about 9/16" of an inch which is the thickness of the bottom of the original case. The result, then, is that a D975 fits with (vertically) about 3/16 of an inch clearance before the top of the new D975 contacts the bottom of the "tubes" in the original Delco case. I elected to not glue or epoxy the new AGM to the inside of the case (possibility of a warranty claim against XS Batteries?) and instead used a spacer to limit vertical movement of the new AGM. Sidewise movement controlled by "smallish" aluminum angle pieces screwed to the bottom plate.
Again, purists may find this a little appalling but it does save the original AC Delco "box" from being thrown on the scrap heap. Maintenance-free batteries, to me, just don't look correct under the hood of cars going on 60 years old. On the flip side is always the possibility of the cable connections loosening up with the passage of time..............life, after all, is something of a gamble.

Re: Odyssey Battery inside Antique Auto Battery
Jack,
Interesting that the Odyssey PC 925LMJ is 525 cranking amps and my XS Power battery is rated at 532 cold cranking amps and 604 cranking amps. The Odyssey, though, may be a better product than the X S Power D975..................time will tell. My "perceived" issue (and I considered the Odyssey) with the 925LMJ battery is that the polarity IS the same as the Delco original and in the close quarters encountered in the case led me to question how I was going to make the connections. I purchased my XS battery from Jegs for $230 with shipping. However, I cannot say that I am fully satisfied with Jegs! The shipping container was literally falling apart as though it had been used a number of times (unwise, given how heavy lead is!) and the container had absolutely NO packing inside and it was much larger than needed to be based on size of the D975. Hence the XS package containing the battery could easily have fallen out of the shipping container. Then too, Jegs does not include an invoice or receipt in the package and I e-mailed them with these issues and their reply was that a receipt could be gotten (from their site) when placing the order. What I was able to copy from their site concerning my order is really not much as far as proof of purchase goes and hence I'm hoping I don't have warranty issues. Admittedly my DC-12 battery application is only partially applicable to your C3 battery but I was hoping that some information could be helpful to others (even yourself) faced with similar issues. Best of luck with your project.

Re: Odyssey Battery inside Antique Auto Battery
Bill,
There are a couple of different ratings but I'm trying to compare the same CCA which for the 925LMJ is only 330 CCA (see partial screen capture from their site below). On the Summit site (I have better luck ordering from them than Jegs on the west coast) they show the XS Power D975 as 604 Amps at 32 degrees, but a zoom in on the D975 picture shows 525 at 32 degrees. Is 32 degrees the same as CCA? Of course they make it difficult to compare apples to apples... Nonetheless, simply by being a larger battery it would stand to reason it would have a higher CCA. A significant increase in CCA was the only reason I considered a more difficult modification than simply going with the 925LMJ.Last edited by Jack C.; May 11, 2023, 12:35 PM.Comment

Re: Odyssey Battery inside Antique Auto Battery
Jack,
In answer to your question, I believe cold cranking amps by definition is at zero degrees F. and cranking amps at thaw/freeze, 32 degrees. Which puts the D975 in a better light; however, are these parameters a defined industry standard or more like tires are rated: more advertising lingo than any precise standard for comparison between brands.

Jack,
Could you edit your post #12 and get rid of all the junk text so as to clean up and shorten the thread?
