When restoring a classic car, every detail matters — the paint, the trim, the chrome, the wiring, and especially the engine bay. But there’s one part many restorers overlook until the hood pops open:
The modern plastic battery.
Bright labels, molded plastic, and warning stickers instantly break the period-correct appearance of any classic vehicle. That’s why Tar Topper was created — to bring back the look of the original tar-top batteries found in vehicles built before 1966 while keeping the convenience and reliability of modern sealed batteries.
In this post, we’ll explain why the tar-top style matters, how our product works, and why thousands of classic-car owners trust Tar Topper for their restorations.
What Is a Tar-Top Battery?
From the early 1900s through the early 1970s, nearly all automotive batteries used a tar-sealed construction. These batteries featured:
-
A flat black “tar top” surface
-
Removable cell caps
-
A square, utilitarian shape
-
Simple branding or no branding at all
This look became iconic — especially under the hoods of early Corvettes, Camaros, Thunderbirds, Mustangs, Tri-Five Chevys, Novas, and countless others.
But original tar-top batteries have long been discontinued due to safety, durability, and environmental regulations.
The Problem With Modern Batteries in Vintage Cars
Modern batteries are great for performance — but terrible for authenticity.
They often feature:
-
Curved plastic tops
-
Molded handles
-
Bright stickers
-
Safety labels
-
Visible manufacturing marks
In a fully restored car, especially one prepared for a concours event or car show, these bright plastic batteries look out of place.
How Tar Topper Solves the Problem
Tar Topper is a cosmetic battery cover that slips over a modern sealed battery to recreate the original tar-top appearance without affecting performance.
Our covers:
-
Fit common battery sizes like Group 24, Group 34 Optima, and 6-volt Optima
-
Install in minutes
-
Require zero modifications
-
Provide realistic vintage cell caps and textures
-
Improve show-car presentation instantly
You get the look of a real tar-top battery with the reliability and safety of today’s sealed batteries.
Which Vehicles Benefit From a Tar Topper?

Why Authenticity Matters
At car shows, judge panels and enthusiasts often look closely at:
-
Wiring routing
-
Factory markings
-
Hose clamps
-
Fender bolts
-
Paint finishes
-
Battery branding
A modern battery can become the most distracting thing in an otherwise flawless restoration. With a Tar Topper installed, your engine bay tells a consistent story — one that fits the period your car represents.
