Cegasa E/Z8 6/600 6V 600Ah Zinc Air Alkaline Battery

When your application runs in a remote location, an unmanned enclosure, or anywhere that a dead battery isn't just inconvenient but a serious problem, the power source you choose matters. The CEGASA E/Z8 6/600 is a 6-volt, 600Ah zinc air alkaline primary battery engineered to deliver reliable, long-duration power in exactly those kinds of demanding environments. Manufactured in Spain by CEGASA — a company with decades of experience in industrial energy solutions — the E/Z8 6/600 is built around a technology that simply outlasts conventional options.

Why Zinc Air Technology?

Zinc air batteries generate power through a reaction between zinc and oxygen drawn from the surrounding air, rather than relying solely on the chemicals sealed inside. The result is a remarkably high energy density in a compact form factor. The E/Z8 6/600 packs 3,120 Wh of nominal energy into a package measuring just 8.5 x 4.25 x 8.9 inches and weighing approximately 18.1 lbs. Compared to standard saline battery technology, the E/Z8 series lasts up to 8 times longer — a difference that dramatically reduces the cost and effort of field service visits and battery replacements.

Consistent Voltage You Can Count On

One of the most important qualities in a battery powering sensitive electronics is voltage stability. Many battery types start strong and gradually fade, which can cause equipment to underperform or behave erratically well before the battery is actually depleted. The E/Z8 6/600 maintains a steady service voltage throughout its useful life, allowing connected devices to operate at their intended performance levels from start to finish. With an initial open circuit voltage of 6.50V and a guaranteed minimum at the warranty limit of 5.80V, there's no guesswork about whether your equipment is getting what it needs.

Runtime Built for the Long Haul

Runtime will vary depending on the current draw of your application, but the E/Z8 6/600 is designed with long-haul performance in mind. Here's what you can expect under continuous 24-hour daily discharge at room temperature:

• At 40 mA: approximately 21 months (15,000 hours)
• At 49 mA: approximately 17 months (12,100 hours)
• At 59 mA: approximately 14 months (10,200 hours)
• At 68 mA: approximately 12 months (8,800 hours)
• At 120 mA: approximately 7 months (4,900 hours)
• At 173 mA: approximately 5 months (3,400 hours)
• At 225 mA: approximately 4 months (2,600 hours)

For applications drawing around 40–68 mA — typical for many IoT devices, security systems, and remote sensors — the E/Z8 6/600 can power your equipment for a full year or more without any intervention.

Safe by Design

Safety is built into the E/Z8 6/600 at a fundamental level. The battery is completely free from thermal runaway, a potentially dangerous condition associated with some other battery chemistries. It contains zero mercury, making it a more responsible choice for both users and the environment. The rugged HIPS (high-impact polystyrene) casing and lid are joined by ultrasonic welding for a sealed, durable enclosure that holds up in the field. A bolted W1/4 connection ensures a secure, stable terminal contact.

Where the E/Z8 6/600 Performs Best

This battery shines in applications that need dependable, low-maintenance power without the option of a hardwired electrical connection. Common use cases include:

• Vacancy and anti-intrusion alarm systems in unoccupied properties, construction sites, and temporary installations
• IoT sensors and remote monitoring devices in the field
• Maritime navigation and signaling equipment
• Telecommunications infrastructure in off-grid locations
• Remote road signage and smart city installations

The E/Z8 6/600 can be stored for up to 2 years under normal conditions without performance loss, so you can stock units confidently and deploy them when needed. With 2 batteries per box and 120 units per pallet, it scales well for both small deployments and larger-volume projects.
