  • Compact D-cell format at 34 mm diameter fits tight spaces
  • 5 Ah capacity delivers sustained energy for critical systems
  • Pure lead-tin VRLA AGM design enables 200+ deep discharge cycles
  • Faston 0.187" termination allows quick, secure wiring

Cyclon 2V 2.5Ah Sealed Lead Acid D Cell

The EnerSys Cyclon 2V 2.5Ah cell is a sealed lead acid D-size battery built for high-rate charge and discharge. It uses a pure lead-tin VRLA AGM design that provides superior deep discharge recovery. This new battery suits equipment needing a robust 2 Volt power source in a 34 mm diameter by 61 mm height form factor.

Upgrading from standard D cells

The Cyclon replaces conventional D cells where longer cycle life and wider temperature tolerance are required. It delivers 200-plus full depth discharge cycles and up to 2000 charge cycles, far exceeding typical primary cells. The jump is worth it for applications that demand reliable rechargeability and a two-year shelf life without maintenance.

Limits of the 0.187" faston interface

The 0.187-inch faston termination limits current to what the tab and connector can safely carry. Operating range spans -65°C to 80°C, but sustained high-rate duty near the extremes will reduce achievable cycles. Capacity is fixed at 2500 mAh, so runtime scales directly with load and cannot be expanded without adding cells.

Questions about this item

Will the 34 mm diameter and 61 mm height fit my D-cell slot?

The cell measures 34 mm in diameter and 61 mm in height, matching the standard D form factor.

How do I connect the 0.187" faston tabs without damaging the seal?

Push the matching quick-disconnect terminals straight onto the tabs; do not solder directly to the terminals.

When should I replace the cell if it sits on the shelf for two years?

The rated shelf life is two years; after that, capacity may drop below the 2.5 Ah rating and the cell should be replaced.
