Product Description
The Cegasa E/Z8 3V 600Ah is a non-rechargeable zinc-air alkaline battery designed for applications that need a higher nominal voltage without sacrificing the long, stable runtime the E/Z8 family is known for. With 3V of output, 600 Ah of capacity, and 1,560 Wh of stored energy, it fills an important gap — covering systems that require more than the standard 1.5V cell but still demand months of continuous, maintenance-free operation.
The Right Voltage for More Applications
Many industrial systems, sensors, and field devices are designed around a 3V supply. Stepping up to a 3V battery means a simpler, cleaner installation — no voltage regulators, no boost converters, no added complexity in the circuit. The E/Z8 3/600 delivers that 3V output directly, while bringing the full advantages of Cegasa's zinc-air alkaline chemistry along with it.
That chemistry is what sets this battery apart from conventional options. By drawing oxygen from the surrounding air as part of its electrochemical reaction, zinc-air batteries store far more energy per unit of weight and volume than traditional alkaline cells. The E/Z8 3/600 lasts up to 8 times longer than comparable conventional zinc batteries — and its output voltage stays within 2% across the entire discharge cycle, so the equipment it powers gets consistent performance from installation through end of service life.
Three Applications, One Common Requirement
Cegasa lists three primary applications for this battery: IoT and telecommunications, cathodic protection, and maritime signaling. Each one has its own demands, but they share a core requirement — reliable, unattended power in locations where maintenance visits are infrequent and downtime carries real consequences.
For IoT and telecom deployments, that might mean a remote sensor network, a field communication node, or monitoring equipment at an unmanned facility. For cathodic protection, it means a steady, continuous current flowing to metal infrastructure buried underground or submerged in water — protecting pipelines, tanks, and other structures from corrosion. For maritime signaling, it means lighthouse lighting, buoy systems, and radio beacons that need to keep working regardless of weather, salt air, or how long it's been since a service crew came by.
In all three cases, the E/Z8 3/600 is built to keep running.
A Stable, Predictable Discharge Curve
One of the most important characteristics of any battery powering critical infrastructure is voltage stability. A battery that starts strong but fades quickly creates problems downstream — equipment may underperform, trigger false alarms, or shut down prematurely. The E/Z8 3/600 avoids this entirely. Cegasa's zinc-air formulation keeps output voltage variation under 2% from full charge through depletion, delivering the same quality of power on the last day of service as on the first.
The battery supports up to 250 mA of continuous current discharge without any reduction in capacity, with intermittent current capability up to 1,000 mA for short-duration peaks.
Durable, Safe, and Simple to Deploy
The E/Z8 3/600 uses the same rugged construction found across the E/Z8 line. Its high-impact polystyrene (HIPS) case is sealed by ultrasound welding, creating a strong, leak-resistant enclosure with no mechanical weak points. The bolted W1/4 terminal keeps field wiring secure under vibration and environmental stress. It's completely free from thermal runaway, making it safe for use in unattended, enclosed, or hard-to-access installations.
The battery contains no mercury or cadmium, keeping disposal straightforward and compliant with modern environmental standards. A 2-year shelf life under normal storage conditions means you can stage replacement stock well in advance without worrying about capacity loss sitting on the shelf.
Frequently Asked Questions
What makes the E/Z8 3V 600Ah different from the 1.5V models in this series?
A: The primary difference is output voltage. The E/Z8 3/600 delivers 3V nominally, making it a direct fit for systems designed around a 3V power supply — no voltage regulation needed. Capacity and energy storage differ as well, but the same zinc-air alkaline chemistry, construction quality, and long-runtime design carry through the entire E/Z8 family.
What applications is this battery best suited for?
A: The E/Z8 3/600 is designed for three main use cases: IoT and telecommunications equipment (remote sensors, communication nodes, monitoring stations), cathodic protection systems (protecting buried or submerged metal infrastructure from corrosion), and maritime signaling (lighthouse lighting, buoy systems, radio beacons). All three share the same need for reliable, long-duration, low-maintenance power.
Is this battery rechargeable?
A: No. The E/Z8 3/600 is a primary (non-rechargeable) battery. When its capacity is depleted, it should be replaced. Because it contains no mercury or cadmium, it meets current environmental disposal requirements.
How does the voltage hold up over the life of the battery?
A: Very consistently. Cegasa's zinc-air formulation keeps output voltage variation within 2% across the full discharge cycle. Unlike conventional batteries that show a gradual voltage drop as they discharge, the E/Z8 3/600 maintains near-flat output — which is critical for equipment that relies on stable voltage to operate correctly.
What are the physical dimensions of this battery?
A: The E/Z8 3/600 measures 4.25 x 4.25 x 8.66 inches (108 x 108 x 220 mm). It connects via a bolted W1/4 terminal and ships 4 units per box, with 240 units per pallet.
Can this battery be used in marine or outdoor environments?
A: Yes. The E/Z8 3/600 is rated for operation across a temperature range of -4°F to 122°F (-20°C to 50°C) with a humidity tolerance of 25–85% RH. Its ultrasound-welded HIPS enclosure resists leaks and holds up in harsh outdoor and marine conditions — making it a reliable choice for maritime signaling and other field deployments.
