Classic car batteries

I suppose I'm the only one who thinks this topic is crazy. Please, drive them, have fun.

I would plan on cutting out the bottom. Don't cut from the side like you did the top but the cut the inside perimeter. That is how I do it. I turn it over and  measuring the thickness  I cut so as to miss the side walls and only cut into the inside perimeter. By cutting on the inside perimeter you will not lose any height. That way you have the option of ether fixing the bottom cut out with a comparable thickness material or leave it cut out.  I am doubtful the cutout will remain intact to reuse once you try and separate it from the epoxy and battery. 

Thanks Bob, I'll give that a shot, at this point I've got nothing to lose...

agm batteries do not live long if over charged ..  most new  fords have agm batterys .  they can be recovered if they are dead but it must be a long slow 1 amp charge rate . if they get hot they dry out and then are trash . if you leave them connected and  the clock kills them while they sit in garage they  might only recover 2 times
we have 24 f motorcraft lead acid batterys in both shelbys and one lasted over 10 years in the 65 .

Probably one reason the Autolite repop AMG battery in my 66 lasted almost 16 years. I never, ever charged it because I was concerned about the over charging issue. Just pulled the neg cable when parked and let the stock charging system take care of that when driving.

I'm with you. While a Day 2 car probably still had its original battery by day 1095 it had a Sears or Pep Boys replacement.........

For anyone wanting to try to replace the inner battery in a repop Autolite case, I was able to find out the battery inside the repop 24F shown in my reply# 18 photo is an Odyssey ODS-AGM28. I assume it would fit in a 27F case as well?

I did this with my crappy Autolite reproduction a couple years ago. Lithium was subsequently recalled due to issue with the internal circuitry so I just put in the largest 12V AGM battery that would go inside the Autolite housing I could buy at Walmart.

Good info. Would you have a link on the battery you used?

Dave, my post is meant to be helpful . You may want to double check your source for what fits inside the repro battery. When I check the specifications for the Odyssey ODS-AGM28 it comes back with 11 X 10 X 8 dimensions. If that is true then it will not come even close to fitting in the group 24 or even the group 27 case.  https://www.amazon.com/Odyssey-Battery-ODS-AGM28-Extreme-AGM/dp/B091G89PJQ/ref=sr_1  Even though the picture looks like it will not fit if you go down and click on to the "See more product details" it gives the dimensions .

Bob, interesting. I got my info directly from Odyssey tech support after giving them the dimensions of the battery in my repop Autolite 24F and sending the same photo in reply# 18. They said it matched their ODS-AGM28, info I gave them was 7 x 6.5 x 5, the info on their website matches those dimensions, 6.9 x 6.6 x 5. https://www.odysseybattery.com/products/ods-agm28-battery-pc925l/. I'm guessing the Amazon info is wrong?

I am skeptical to say the least. Certainly one of them is wrong. I could have said nothing but I didn't want one of our forum members ordering a expensive battery that they could not use on my conscience if I didn't speak up. I do need to buy something that fits . Please let us know after you buy that one that it fits.

Actually I gave up on it this time. The inner battery was encased on the bottom in one inch of rock solid epoxy, also one side. Trying to get it out would have completely destroyed the case IMO. Still interested if the ODS-AGM28 fits though, if I can find one locally I'll measure and report back. The O'Reilly's website does show the same dimensions as Odyssey...https://www.oreillyauto.com/detail/c/extreme/battery---accessories/batteries/31624da3221a/odyssey-extreme-battery/ody1/odsagm28.

An ODYSSEY PCM680 fits. I cut up a re-pop AUTOLITE 24F from the bottom and gutted it. (Gee, that was fun!)

When I go to the Odyssey website and put PCM680 it comes back with no results. Maybe that number is a old obsolete number because none on the website start with a OP, another MFG or a typo.

I forget exactly but it was an Everstart Powersport AGM motorcycle/ATV battery,right at 400cca, approx 6.5"x5"x7"

Bob, plug in Odyssey PC680 on eBay.  Bunch of listings. There are variations: C680, PCM680, PCMT680, etc.
