Enersys CYCLON 0819-0010 D Monobloc - 4V 2.5Ah Sealed Lead Acid Battery

Reliable 4-Volt Power in One Compact Unit

When your specialized equipment requires a steady 4-volt power source, the Enersys CYCLON 0819-0010 is the dependable choice. Known as the "D Monobloc," this battery combines two of Enersys' high-performance 2.5Ah cells into a single, rugged housing. It is a favorite for professionals maintaining emergency lighting, medical electronics, and industrial controls where a standard battery just won't cut it.

The Advantage of Pure Lead Technology

What makes the CYCLON 0819-0010 different from a typical rechargeable battery? It all comes down to the materials. While cheaper batteries use lead alloys that break down over time, Enersys uses 99.99% pure lead and a unique spiral-wound design. This means you get a battery that is built to perform for the long term:

• 15-Year Design Life: This battery is engineered to stay healthy for up to 15 years in standby applications. You can install it and trust that it will be ready to work when you need it most, without the need for frequent replacements.
• Tough in Any Weather: From freezing outdoor boxes to hot equipment rooms, this battery keeps working. It is rated for temperatures as low as -40°F and as high as 140°F.
• Fast Charging: The pure lead plates allow the battery to accept a charge much faster than standard lead-acid batteries, so your backup system is back at full strength shortly after power is restored.

Maintenance-Free Peace of Mind

The 0819-0010 is completely sealed and maintenance-free. There is no liquid to check and no risk of acid leaks damaging your sensitive equipment. Its non-spillable design gives you the flexibility to mount it in almost any position. Housed in a sturdy outer casing, it is built to resist the vibrations and bumps of a busy workplace. It’s the simple, "set it and forget it" solution for your critical 4V power needs.
