Product Description
Some applications demand more than a standard battery can deliver. The Cegasa E/Z8 1.5V 2400Ah is an industrial-grade, non-rechargeable zinc-air alkaline battery built for continuous, long-duration power in environments where reliability is critical and maintenance is minimal. With 2,400 Ah of nominal capacity and 3,120 Wh of stored energy, it's a serious power solution for serious installations.
Designed for Industrial Demands
The E/Z8 2400 carries the same zinc-air chemistry that sets this battery family apart — using ambient oxygen as part of its electrochemical process to achieve an exceptional energy density in a field-ready package. The result is a battery that lasts up to 8 times longer than conventional zinc alternatives, reducing the frequency of replacements and the operational costs that come with them.
Cegasa classifies this as an industrial battery, and its specs back that up. It supports up to 1,000 mA of continuous current discharge without any reduction in capacity, and handles peak draws of up to 10 A. It's also completely free from thermal runaway, meaning it can operate safely in unattended or remote installations without the risk of overheating.
A Natural Fit for Cathodic Protection
The E/Z8 2400 is purpose-built for cathodic protection systems — one of the most demanding applications in industrial battery use. Cathodic protection keeps metal structures like buried pipelines, storage tanks, and underground infrastructure safe from corrosion by supplying a small, continuous electrical current. That current needs to flow reliably for months or years at a time, from a power source that doesn't require constant attention.
This battery is engineered for exactly that. Its discharge curve is flat and stable, maintaining voltage well above the operating threshold throughout its service life. The open-circuit voltage starts at 1.625V and holds above 1.45V through the warranty period — providing consistent, dependable output for systems that can't tolerate fluctuation.
Long Runtime, Low Maintenance
At 155 mA of continuous discharge, the E/Z8 2400 runs for up to 21 months — over 15,400 hours of uninterrupted operation. Even at significantly higher current levels, runtime remains impressive:
- 266 mA continuous: approximately 13 months (9,000 hours)
- 477 mA continuous: approximately 7 months (5,000 hours)
- 689 mA continuous: approximately 5 months (3,400 hours)
For installations in remote locations, harsh terrain, or hard-to-access infrastructure, this level of endurance dramatically reduces how often crews need to visit for battery service.
Built Tough, Ready for the Field
The E/Z8 2400 is housed in a rugged HIPS (high-impact polystyrene) case sealed by ultrasound welding — a construction method that creates a strong, leak-resistant bond without the weak points that mechanical fasteners can introduce over time. Connections are made via a bolted W1/4 terminal, keeping wiring secure in installations subject to vibration, temperature changes, or other environmental stresses.
The battery is completely mercury- and cadmium-free, making it a responsible choice for field use and straightforward to handle at end of life. A 2-year shelf life under normal storage conditions means you can keep units staged for planned replacements without worrying about stored capacity degrading.
Frequently Asked Questions
What is the Cegasa E/Z8 1.5V 2400Ah primarily used for?
A: This battery is designed for industrial applications that require long, continuous, low-maintenance power. Its primary application is cathodic protection — a technique used to prevent corrosion in buried or submerged metal structures like pipelines, tanks, and underground infrastructure. It's also well-suited for other demanding, low-drain industrial applications.
How does this battery differ from a standard alkaline battery?
A: The E/Z8 2400 uses zinc-air chemistry, which draws on ambient oxygen as part of its reaction. This allows it to store significantly more energy than a conventional alkaline cell of similar size. The result is up to 8 times the runtime of traditional zinc batteries, along with a much flatter discharge curve and more stable voltage over time.
Is this battery rechargeable?
A: No. The E/Z8 2400 is a primary (non-rechargeable) battery. Once its capacity is depleted, it should be replaced and disposed of properly. Because it contains no mercury or cadmium, it meets modern environmental disposal requirements.
How long will this battery last in my system?
A: Runtime depends on your system's current draw. At 155 mA continuous discharge, expect up to 21 months (approximately 15,400 hours). At 266 mA, around 13 months. At 477 mA, approximately 7 months. For best results, this battery should be matched to a low-drain application running at or below 1,000 mA continuous current.
What are the physical dimensions and weight?
A: The E/Z8 2400 measures 8.5 x 4.25 x 8.9 inches (216 x 108 x 226 mm) and weighs approximately 18.1 lbs (8.2 kg). It connects via a bolted W1/4 terminal and ships 2 units per box.
Can this battery be used in unattended or underground installations?
A: Yes. The E/Z8 2400 is free from thermal runaway and housed in an ultrasound-welded HIPS case, making it a safe and reliable choice for unattended, underground, or otherwise hard-to-access installations. Its long runtime further reduces how often maintenance visits are needed.
