EnerSys Cyclon 2V 5Ah X Cell

The EnerSys Cyclon 2V 5Ah sealed lead-acid X cell delivers 5000 mAh capacity in a 45 mm diameter by 73 mm cylinder. Pure lead-tin VRLA AGM chemistry supports high-rate charge and discharge across a -65 to 80°C range. The 0.250" faston termination enables quick series or parallel wiring. It suits standby power, portable instruments and cyclic UPS modules.

Ideal for compact cyclic power

Builders needing a rugged, maintenance-free cell for frequent deep cycling will value the 200-plus full-depth cycles and superior recovery after deep discharge. The two-year shelf life simplifies spares holding. Buyers who want more storage per unit volume or a lighter chemistry for weight-critical designs should evaluate alternatives.

5000 mAh sealed lead-acid capacity

The 5 Ah rating at 2 V defines the total energy available per cell and determines how many cells are required to reach a target voltage or runtime. Verify that the 45 mm diameter and 73 mm height fit the battery compartment before ordering.

Questions about this item

What does the 2 V 5 Ah rating mean when the cell is installed in equipment?

It supplies a nominal 2 V and can deliver 5 Ah, so a 1 A load would run for about five hours before the voltage drops to the recommended cut-off.

What does the 0.250" faston termination cap in practice?

The 0.250" faston tabs accept standard quick-disconnect crimp terminals, limiting you to connectors rated for that tab width and the cell's 5 Ah discharge capability.

Will the 45 mm diameter by 73 mm height X-size cell fit in my existing battery holder?

The cell measures 45 mm in diameter and 73 mm tall, so it fits any holder or tray designed for the Cyclon X form factor with those exact dimensions.
