Product Description
When your application can't afford to run out of power, you need a battery built for the long haul. The Cegasa E/Z8 is a high-capacity, non-rechargeable zinc-air alkaline battery engineered for demanding, low-drain applications where reliability and longevity aren't optional. With 1,200 Ah of nominal capacity and 1,560 Wh of stored energy, it delivers a level of performance that conventional batteries simply can't match.
Why Zinc-Air?
Zinc-air batteries work by drawing oxygen from the surrounding air as part of their electrochemical reaction. That design allows them to store a remarkable amount of energy without the added weight and bulk of a traditional sealed chemistry. The practical result? Cegasa's E/Z8 lasts up to 8 times longer than conventional zinc batteries — making it an ideal choice when battery swaps are difficult, costly, or simply not practical.
Purpose-Built for Low-Drain, Long-Duration Applications
The E/Z8 1200 is designed for installations that run continuously at low current levels over extended periods. Common applications include:
- Railway signaling and trackside equipment
- Remote IoT sensors and monitoring stations
- Telecommunications infrastructure in the field
- Cathodic protection systems for pipelines and buried structures
At 80 mA of continuous discharge, this battery can run for up to 21 months — more than 15,000 hours of uninterrupted operation. Even at higher demand, it holds its own: at 136 mA, expect approximately 12 months of runtime. For remote installations where maintenance visits are infrequent and downtime is costly, that kind of endurance makes a real difference.
Stable Voltage From Start to Finish
The E/Z8 1200 maintains a consistent open-circuit voltage of 1.625V at the start of its service life, holding above 1.45V through the warranty period. Under load, the discharge curve stays flat and predictable — exactly what sensitive electronics and monitoring equipment need to operate reliably over months of continuous use.
Safe, Durable, and Ready for the Field
This battery is free from thermal runaway, meaning there's no risk of overheating or uncontrolled chemical reactions — even under demanding field conditions. The rugged HIPS (high-impact polystyrene) case is sealed by ultrasound welding, creating a tough, leak-resistant enclosure that holds up in challenging environments. Connections are made via a secure bolted W1/4 terminal, keeping wiring firmly in place even where vibration is a factor.
The E/Z8 1200 is completely mercury- and cadmium-free, keeping it in line with modern environmental standards and simplifying disposal. A 2-year shelf life under normal storage conditions means you can keep units on hand for planned replacements without worrying about capacity loss while they wait.
Frequently Asked Questions
What applications is the Cegasa E/Z8 1.5V 1200Ah best suited for?
A: This battery is designed for low-drain applications that require long, continuous runtimes without frequent maintenance. Common uses include railway signaling, remote IoT and telecommunications equipment, and cathodic protection systems for pipelines and buried infrastructure.
Is the E/Z8 1200 rechargeable?
A: No. The E/Z8 1200 is a primary (non-rechargeable) battery. Once depleted, it should be disposed of responsibly and replaced. Because it's mercury- and cadmium-free, it meets modern environmental disposal standards.
How long will this battery last in my application?
A: Runtime depends on your system's current draw. At 80 mA continuous discharge, the battery lasts up to 21 months (approximately 15,000 hours). At 136 mA, expect around 12 months of runtime. At 241 mA, approximately 7 months. For best results, match the battery to a low-drain application where it can operate at or below 500 mA continuous current.
What are the physical dimensions and weight?
A: The E/Z8 1200 measures 4.25 x 4.25 x 8.7 inches (108 x 108 x 220 mm) and weighs approximately 8.6 lbs (3.9 kg). It connects via a bolted W1/4 terminal.
Is this battery safe to use in remote or unattended installations?
A: Yes. The E/Z8 1200 is free from thermal runaway, which means it won't overheat or experience uncontrolled chemical reactions under normal operating conditions. Its ultrasound-welded HIPS casing also provides a secure, leak-resistant enclosure suited for long-term field deployment.
How should the E/Z8 1200 be stored before use?
A: Store the battery under normal conditions (away from extreme heat, moisture, and direct sunlight). Under proper storage, it maintains its capacity for up to 2 years — making it practical to keep spare units on hand for scheduled replacements.
