Why Choose Enersys Cyclon Batteries?

Enersys Cyclon batteries are built differently. Unlike conventional lead acid batteries, they use high purity lead plates that offer longer service life and better performance. This unique construction allows them to handle extreme temperatures and resist the vibrations that often damage standard power sources.

One of the biggest advantages of the Cyclon line is its versatility. You can mount these batteries in virtually any position, making them ideal for tight spaces or equipment where a standard battery orientation just will not fit. They are the trusted choice for:

  • Telecommunications backup power
  • Emergency medical equipment
  • Industrial control systems
  • Uninterruptible Power Supplies (UPS)

Finding the Right Cyclon Battery

Because Cyclon batteries come in different configurations, it is important to match your specific voltage and capacity requirements. Most of our inventory focuses on two main voltage levels: 2 volt and 4 volt.

When shopping our catalog, you will notice both individual cells and "monoblocs." Individual cells are often used for custom builds or specific size constraints. Monoblocs are pre-assembled units that combine cells into a single package, which can simplify installation if your equipment calls for a specific voltage stack. If you are replacing an existing unit, always check the label on your current battery to ensure you select the same voltage and size profile.

Frequently Asked Questions

Are Enersys Cyclon batteries rechargeable?

A: Yes. These are rechargeable sealed lead acid batteries. They are designed to withstand many charge and discharge cycles, making them excellent for standby or cyclic applications.

What is the difference between a Cyclon cell and a monobloc?

A: A single cell is an individual battery unit. A monobloc is a group of these cells connected together in a single case to provide a higher voltage or capacity while maintaining a compact footprint.

Can I use a Cyclon battery in any position?

A: Yes. Thanks to their sealed construction and high purity lead design, Cyclon batteries are spill proof and can be mounted in almost any orientation without compromising performance.

How do I know which voltage I need?

A: Always refer to the part number on your old battery or the owner manual for your equipment. Cyclon batteries typically come in 2V or 4V increments, and using the wrong voltage can damage your device.
