I wonder if anyone makes period correct decals for one. So you could get a new battery but the original stock look.
I get that question alot. I wished we made period correct wet cell reproductions.
Interstate works with Johnson Controls who makes the batteries for them.
There's only 3 major wet cell battery manufacturers in N. America.
Interstate/johnson Controls
East Penn Deka
Exide
So far none of them have stepped up to the plate to do this.
From what I have gathered and I'm not a 100% sure on this:
The reproduction red top capped batteries are an Optima within the casing.
Johnson Controls is the mfg'r of the Optima. Optima's don't like heat. They're an AGM. (Aluminum Glass Matt)
Wet cells (
SLI as they're called, short for starting, lighting, ignition) transfer heat out to the outer casing better in engine compartments than Optima's. Optimas are great for cooler locations and/or cooler climates IMO. They have a hell'va great A/h to them. When properly maintained, it's [possible to see up to 7-8 yrs. from them.
