Twin Power Shocker Battery For Harley Softail / Dyna / V-Rod / Sportster 1991-2026
Twin Power Shocker AGM Battery: Premium Starting Power for Harley-Davidson
The Twin Power Shocker Battery (TPZ20HL-BS) is engineered specifically for the demanding environment of American V-Twin motorcycles. Whether you ride a classic 1991 Softail or a modern 2026 model, this battery provides the high-amperage output and rugged durability required to keep your machine performing at its peak. Built with advanced AGM (Absorbed Glass Mat) technology, the Shocker series offers a significant upgrade over standard lead-acid batteries in terms of cranking power, safety, and lifespan.
High-Output Performance: 310 CCA
V-Twin engines require substantial energy to overcome high-compression resistance during startup. The Twin Power Shocker delivers a consistent 310 Cold Cranking Amps (CCA), providing a sharp, reliable burst of power even in cold weather conditions. With an 18Ah capacity, it also offers excellent reserve power for motorcycles equipped with additional electronics, such as security systems, LED lighting, or upgraded audio components.
Engineered for Extreme Vibration Resistance
Harley-Davidson motorcycles are known for their unique vibration profiles, which can be devastating to standard batteries. The Shocker series features extra-thick internal plates and a reinforced “full-frame” power path design. These components are lock-bonded together to minimize plate movement, preventing the internal shorts and mechanical failures that often plague lesser batteries. This heavy-duty construction ensures a much longer service life on the road.
Patented Flush-Mount Terminals
One of the standout innovations of the Twin Power Shocker is its patented flush-mount threaded posts. These terminals feature dual connection points and are designed to provide maximum surface contact for battery cables. By utilizing an embedded brass nut, these terminals offer up to 50% better conductivity than traditional lead or stainless steel terminals. This design eliminates the need for annoying spacers or adapters, ensuring a clean, “plug-and-play” installation.
Maintenance-Free & Factory Activated
The TPZ20HL-BS is Factory Activated, meaning it arrives at your door fully charged, sealed, and ready to install. Because it uses a sealed VRLA (Valve Regulated Lead Acid) design, there is no need to add acid or check water levels. The 100% leak-proof and spill-proof construction protects your bike’s frame and chrome from corrosive damage, allowing for worry-free riding in any terrain.
