CYCLON Battery 4V Monoblocs

Cyclon 4V Monoblocs: two cells in a single block

The 4V monobloc integrates 2 spiral-wound pure lead Cyclon cells connected internally in series, delivering a nominal 4V in a single case. It keeps the low internal resistance and high momentary discharge capacity of Cyclon technology, with the mounting convenience of a compact block instead of loose cells.

Common models and uses

• 0809-0010 (5 Ah) — industrial instrumentation and control equipment.
• 0809-0012 (8 Ah) — avionics systems and critical backup.
• 0859-0010 (25 Ah) — industrial applications needing more autonomy.

How to choose between 2V, 4V and 6V

If your equipment runs on 2V, the Single Cell is enough; if you need 6V, check the 6V monobloc. Use our battery comparator to compare capacities and pick the exact reference.

Frequently asked questions about the Cyclon 4V monobloc

What's the difference between the 4V monobloc and two loose 2V cells?

Electrically it's equivalent to 2 cells in series, but the monobloc integrates them in a single case, simplifying mounting and wiring.

Is it compatible with avionics applications?

Yes, that's one of its typical applications thanks to its vibration tolerance and compact, sealed construction.

How long does a Cyclon 4V monobloc last in industrial use?

Sharing the Single Cell's spiral-wound pure lead technology, it's built for deep discharge cycles and continuous float duty over years of service.
