Can you guys give me the distance from the back side of the front battery retainer to the center of the hole in the rear battery retainer. It would be nice if you could share your serail number with me. Ihave been told that my retainers were not put in the proper place as the reason why my repo battery is loose. Thanks, Keith Majure

Re: 1970 Loose Battery

I don't have that dimension handy, but I may be able to get it soon if no one else has it. However, I really consider that the chances of the forward clamp and rear retaining block (to which fastens the rear clamp) being improperly placed to be near "zilch". The battery compartment was pre-drilled and I would very much doubt that there would have been an error in the hole locations. If there had been, it likely would have affected a lot of cars. Also, as far as I know, the locations of the front and rear clamps did not change over the 68-82 period. Of course, if there is obvious evidence of a repair to the battery compartment, then who knows? If everything appears to be original, I seriously doubt a problem with the positioning of the clamps.
One common problem which can result in a loose battery is the failure of either the front or rear clamps from properly engaging with the "slots" in the battery base. Sometimes, this can take a bit of "re-positioning" to achieve. However, I'd first make sure that the "slots" in the battery are capable of properly articulating with the clamps. If they're not then that's the problem and that means the problem is with the battery and nothing else.In Appreciation of John Hinckley -

Re: 1970 Loose Battery
Keith,
I've had the same problem with the reproduction R89 batteries. I think its the battery being to small and not the hold downs.Comment

Re: 1970 Loose Battery
Joe,Thanks for your response. I am just trying to get all of the information I can before I go back to the repo battery supplier. My car has not been damaged. I have tried to reposition the battery and the rear retainer. I guess I need to be looking for the dimension of the original battery also. As of this date and time no one has give me any measurements. ThanksComment

Re: 1970 Loose Battery
Terry, Thanks for your reply I don't have a problem with acid eaten rivets, just a small battery in a large hole is what I am thinking. I called the supplier and ordered a battery for a late 70 454 AC car and was shipped a R79W. Upon delivery of my battery I pull out the old judging manual and it says this late car should have a R89W. A call to the supplier resulted in a new decal to take place of the R79W. The supplier stated the only difference was the sticker. I will take any help you can give me. Thanks Keith MajureComment

Re: 1970 Loose Battery
Dave, I agree now what is our recourse? How is NCRS juding a little battey in a big hole? For $350.00 it should a least not slide around in the car. Thanks Keith MajureComment

Is the hole in the clamp for the bolt a slot? I have pushed the clamp towards the battery while tightening the bolt with good results on some cars.

Unless this battery has a more-or-less serious deviation from the original battery size or deviation from the "slots" on the bottom which articulate with the clamps , I would think that it should "tighten up". As Lyle mentioned, the rear clamp is slotted so some adjustment is available for slightly different battery widths.
I can tell you that the last Delco Group 78 battery that I installed fit perfectly and tightened down perfectly. The Delco Group 78 is anything but a reproduction battery; it's just a replacement battery. If it will fit properly and the expensive reproduction battery won't, then I'd say there's a real problem.In Appreciation of John HinckleyComment

Re: 1970 Loose Battery
Lyle, It is a slot and when I pushed it up to the battery and held it while I tighten it only helped some. Keep thinking.ThanksComment

Re: 1970 Loose Battery
Joe, I hate say it but when I bought the car it had a Wal-Mart battery in it and it fit very well. At this time it appears I have had an expensive lesson. Thanks, Keith MajureComment

Re: 1970 Loose Battery
Keith,
I fully agree, that at those prices it should fit perfectly. The R89W's I bought in the past for $200/ea. lasted about 2 or 3 years, which adds up fast. I guess the technology is much better but the price has near doubled also. If all the hardware is installed the loose battery should not cost you any points on the judging field but thas no excuse for a battery that may be too small.Comment

Re: 1970 Loose Battery
Keith,
I don't know which battery is correct or what size it should be for your car. But standard battery group dimensions are set by the Battery Council International (BCI) here's a link you can use to compare the size of your battery to their specifications for battery group sizes...
