EnerSys Cyclon 0819-0010 4 V 2.5 Ah Monobloc Pure-Lead SLA – Fast-Charge Backup Cell
The EnerSys 0819‑0010 is a robust 4 V, 2.5 Ah monobloc battery featuring a pure-lead AGM (Absorbent Glass Mat) design, built for unparalleled reliability. Housed in a sturdy steel can with a high-pressure safety vent, this maintenance-free battery is leakproof and impact-resistant, offering exceptional resistance to damage from shocks or rough handling. Its compact dimensions (approximately 3.13″ × 1.81″ × 2.75″) and lightweight form (around 1.25 lbs) deliver excellent energy density, making it ideal when space and weight constraints matter. It also delivers fast charge capabilities, restoring significant power in under an hour—perfect for quick recovery post-power failure.
Engineered for demanding environments, the 0819‑0010 shines in applications such as emergency lighting, UPS systems, medical devices, telecom, and aerospace equipment. Its sealed AGM construction allows for safe operation in enclosed or occupied areas—think offices, hospitals, or aircraft cabins—with minimal off-gassing under normal conditions. The battery operates reliably under extreme temperatures and, with a long design life spanning multiple years and hundreds of cycles, significantly reduces replacement frequency and lifecycle costs.
