Hi Scotty, love your channel. Thank you for all you do. I own a 1971 Cadillac Sedan DeVille with the 472 V8. 71,000 original miles. Presently restoring the car to its stock appearance, i'm a purist when it comes to antique and classic automobiles. My question is, should I continue using a 810 CCA battery which to my knowledge would be to OEM specifications or use something higher in number or lower. When I look in the owners manual it says "R 71S." The only info i could find online is that it's a GM Delco battery code. I found one place who has that type of battery and it's "Auto Zone." Would it be okay to keep using a 810 CCA in this type of car? Thank you for any input you can give me. Take care.
something higher in number or lower.
Don't go lower. That huge almost 8L engine needs significant oomph to start. You can go higher, as long as it fits in the battery tray. Watch the height too. If it's too weird a size then you might need to replace the tray. Other than that, a battery is a battery.
this company makes replica batteries if you want

Hi, I had a feeling I shouldn't go lower on the cranking amps but I thought it wouldn't hurt to ask. I'll stick with the type that I have in there, it seems to fit well with ample working room. Thanks for your input, much appreciated.
Batteries made by even Wal-Mart are just fine, as long as it meets the CCA requirements in the owner's manual. I have a 1979 Pontiac with a Wal-Mart battery. The battery is made by the same manufacturers as so-called "name-brand" batteries, Wal-Mart just slaps its own name on it.
My fuel pump went out two years ago in that car, while I was pretty far away from home. I tried to restart it so many times over the course of two hours, the battery died. After I narrowed it down to the fuel pump, I charged the battery and ever since, it's been perfectly fine. Wal-Mart batteries are just as rugged as name-brand batteries, and way less expensive; I bought it for $50.
Thanks, Justin. I'll check out a Walmart version, do some price comparisons. I'm not loyal to a certain brand of battery perse just as long as I have the proper CCA for this car.
