Cegasa Zinc Air Alkaline Batteries

The Advantage of Zinc Air Alkaline Technology

When it comes to remote or long-term power, most batteries have a major weakness: they lose power even when they aren't being used, or their performance drops significantly as the battery drains. Cegasa solves this with Zinc Air Alkaline technology. By pulling oxygen from the atmosphere to create a chemical reaction, these batteries pack up to five times more energy into the same space as a traditional lead-acid or standard alkaline battery.

Reliable Power for Years, Not Months

One of the biggest benefits for our customers is the "maintenance-free" nature of these batteries. Because they have an incredibly low self-discharge rate, they can sit on a shelf for up to two years with almost no loss in capacity. Once activated, they provide a constant voltage that stays steady until the battery is nearly empty. This makes them the perfect choice for:

• Historic & Antique Equipment: The Cegasa EN6 is the gold standard for enthusiasts restoring vintage No. 6 equipment, like magneto telephones and self-winding clocks.
• Electric Fencing: Keep your perimeter secure without having to swap out batteries every few weeks.
• Navigation & Signaling: Ideal for marine buoys, railroad signals, and emergency lighting where reliability is a matter of safety.
• Remote Monitoring: Perfect for IoT devices and weather stations in locations that are difficult to access.

Frequently Asked Questions

How do I "activate" a Cegasa battery?

Cegasa batteries are shipped with a protective seal over the air holes. The battery remains inactive and "fresh" as long as this seal is in place. When you are ready to use it, simply remove the sticker. We recommend waiting about two minutes after removing the seal before installing the battery to allow the internal chemistry to fully oxygenate and reach its peak voltage.

Can I use these in any weather?

Yes. These batteries are designed to work in tough environments, with an operating range from -4°F up to 122°F. They are also resistant to high humidity, making them a favorite for outdoor use in agricultural and maritime settings.

Are they environmentally friendly?

Cegasa batteries are free of heavy metals like lead, cadmium, and mercury. Because one Cegasa battery can often do the work of several standard batteries, you also end up with less waste to recycle at the end of the battery's life.
