## Description

**Cyclon Battery 2V Single Cell**: an individual 2-volt cell built with spiral-wound pure lead AGM technology (EnerSys/Cyclon). The cylindrical winding lowers internal resistance and withstands high discharge peaks without damaging the plates. Available from 2.5 to 25 Ah.
It's the standard choice for telecoms, medical equipment and industrial instrumentation that need reliable backup power, mountable in any position, even for applications with high momentary discharge.

## Cyclon 2V Single Cell: the spiral-wound pure lead cell

Each Cyclon cell delivers a nominal 2V from pure lead electrodes wound in a spiral, a construction very different from the flat plates of a conventional AGM. This gives low internal resistance, the ability to deliver very high momentary discharge currents, and good vibration tolerance, so it can be mounted in any orientation without electrolyte leakage.

### Common models and applications

- **0810-0004** (2.5 Ah) — instrumentation and low-consumption portable equipment.
- **0800-0004** (5 Ah) — telecoms and alarm systems.
- **0820-0004** (8 Ah) — medical equipment and rack backup.
- **0850-0004** (25 Ah) — industrial applications needing more autonomy.

### How to choose the right Cyclon cell

If your equipment needs more than 2V, combine several cells in series: 2 cells give 4V (see [Cyclon 4V Monoblocs](/gb/cyclon-battery-4v-monoblocs)) and 3 cells give 6V (see [Cyclon 6V Monoblocs](/gb/cyclon-battery-6v-monoblocs)).

## Frequently asked questions about the Cyclon 2V battery

### **What's the difference between a Cyclon 2V and a conventional AGM?**

Cyclon uses spiral-wound pure lead instead of flat plates, which lowers internal resistance and allows higher-intensity discharges with less wear.

### **Is it compatible with equipment needing 4V or 6V?**

The single cell is 2V; for higher voltages several cells are combined, or a Cyclon 4V or 6V monobloc is used directly.

### **How long does a Cyclon battery last in backup applications?**

Service life depends on usage pattern and temperature, but the spiral-wound pure lead technology is designed for deep discharge cycles and continuous float duty in telecom and industry.
