Product Description
Superior Capacity for Demanding Applications
The Cegasa 6V 45Ah Zinc Air Alkaline Battery delivers exceptional performance for industrial, commercial, and remote applications where long runtime and reliability are essential. With 45Ah capacity (234Wh), this battery provides 2-3 times the endurance of typical 6V alkaline batteries found in hardware stores, which typically max out at 17-20Ah. This dramatically extended capacity means fewer battery changes, reduced maintenance costs, and longer operational periods for critical systems—especially valuable for remote installations where access is difficult or infrequent.
Advanced Zinc Air Technology
Cegasa's proprietary zinc air alkaline chemistry uses a specially formulated manganese dioxide cathode that is continuously regenerated by oxygen from the air. This innovative design allows the battery to store significantly more anodic active material compared to conventional alkaline batteries, resulting in exceptional energy density in a compact, lightweight package. While the voltage may be slightly lower than competitors during the first few days of use, the Cegasa battery maintains higher voltage far longer—continuing to deliver reliable power long after conventional batteries have expired. The result is runtime comparable to premium primary lithium batteries but at a fraction of the cost.
Built for Harsh Environments
Engineered for reliability in demanding conditions, this battery operates across an impressive temperature range from -20°C to +50°C (-4°F to 122°F), making it suitable for outdoor installations in extreme climates. The extreme vibration resistance ensures dependable performance in mobile applications, agricultural equipment, telecommunications infrastructure, and transportation systems where constant movement and mechanical stress would compromise lesser batteries. The 100% safe technology eliminates explosion and spill risks, protecting both personnel and equipment in industrial environments.
Versatile Applications
Perfect for autonomous systems requiring long-term, reliable power without frequent intervention. Common applications include time and data stamping machines, telecommunications equipment, road signs and traffic control systems, agricultural monitoring and control systems, remote weather stations, security systems, emergency lighting, parking meters, and outdoor clocks. The compact dimensions (2.6" x 2.6" x 3.88") fit standard battery compartments while the lightweight design simplifies installation and handling. Environmental responsibility is built in—completely mercury-free and cadmium-free construction meets modern environmental standards while delivering the performance industrial applications demand.
Long-Term Value
The exceptional shelf life—just 5% capacity loss in one year and 8% in two years—makes this battery ideal for backup power systems, seasonal equipment, and emergency preparedness stockpiles. Store spare batteries with confidence knowing they'll retain their capacity when needed. The constant voltage output ensures consistent device performance throughout the battery's service life, eliminating the gradual performance degradation common with other battery chemistries. Made in Spain by Cegasa, a trusted manufacturer of specialty batteries, each unit is ready for immediate use without adding reagent liquids or special preparation—simply install and rely on years of maintenance-free power.
Frequently Asked Questions
How does 45Ah compare to regular 6V lantern batteries?
A: Standard 6V alkaline batteries typically provide 17-20Ah of capacity. The Cegasa 45Ah battery delivers more than double the capacity, meaning it will run your equipment 2-3 times longer between replacements. This extended runtime is especially valuable for remote installations where access is difficult or costly.
What makes zinc air batteries different from regular alkaline batteries?
A: Zinc air batteries use oxygen from the air as part of the chemical reaction, allowing more energy-producing material to be packed into the same space. This results in much higher energy density—more power in a smaller, lighter package. The Cegasa zinc air design provides exceptional capacity comparable to premium lithium batteries at a much lower cost.
How long can I store these batteries before use?
A: Cegasa zinc air batteries have excellent shelf life with only 5% capacity loss after one year and 8% after two years of storage. This makes them ideal for emergency backup systems, seasonal equipment, or keeping spares on hand for critical applications.
Can this battery handle outdoor installations?
A: Yes. The Cegasa 6V 45Ah is specifically designed for outdoor and industrial use. It operates reliably in temperatures from -20°C to +50°C (-4°F to 122°F) and features extreme vibration resistance. It's commonly used in road signs, agricultural equipment, telecommunications infrastructure, and other outdoor applications.
Is this battery safe to use?
A: Absolutely. The zinc air alkaline chemistry is 100% safe with no danger of explosion or spills. The battery is also environmentally friendly—completely mercury-free and cadmium-free. It's non-hazardous and safe for workers to handle and install.
What applications is this battery best suited for?
A: This battery excels in applications requiring long runtime with minimal maintenance: autonomous systems, telecommunications equipment, road signs and traffic control, agricultural monitoring systems, time/data stamping machines, remote weather stations, security systems, emergency lighting, parking meters, and outdoor clocks. It's ideal anywhere access is limited or battery changes are costly.
Does this battery need any maintenance or preparation?
A: No. The Cegasa 6V 45Ah is completely maintenance-free and ready for immediate use right out of the package. Unlike some industrial batteries, there's no need to add liquids, charge before use, or perform periodic maintenance. Simply install and it will provide years of reliable power.
How does the voltage compare to other batteries over time?
A: During the first few days, zinc air batteries may have slightly lower voltage than fresh alkaline batteries. However, the Cegasa maintains higher voltage far longer throughout its discharge cycle. While conventional batteries experience steady voltage decline, the zinc air design provides more consistent performance and continues delivering usable power long after other batteries have expired.
What batteries does this replace?
A: The Cegasa 6V 45Ah replaces Duracell MN908, Energizer 529, Eveready 1209, Panasonic H4R25X, Rayovac 806 (LR20), Rayovac 808 (LR25), Rayovac 941, and Varta 430. If your equipment uses any of these part numbers, the Cegasa is a compatible, higher-capacity replacement.
Should I write the installation date on the battery?
A: Yes, that's a great practice. Since these batteries can provide several years of service, writing the installation date on the casing with a permanent marker helps track replacement schedules. For critical applications, we recommend periodic voltage checks to ensure optimal system performance.

Customer Reviews
I needed these special zinc air lantern batteries for powering special instruments at my worksite. My normal supplier was not available to provide the batteries on short notice, but it was no issue for Battery Mart. Ordering was easy and the batteries were received within a few days. The batteries themselves are in excellent condition and work as expected.
Product is what is advertised and fast delivery - great service!
Before getting terribly excited about this product let me say that I haven't even cracked the seal to activate it...yet. What I'm excited about is that a zinc air battery of high capacity has been made available in some form other than a hearing aid. Make them bigger. Sell more. The economy of scale will bring prices down even further. Thank you.
