Product Description
Bring Historic Equipment Back to Life
The Cegasa EN6 is the modern solution for powering vintage and antique equipment that requires the classic No. 6 battery format. Originally popularized around 1950 and first used in 1893 for explosive engine ignition, the No. 6 battery remains essential for collectors, historians, and enthusiasts who maintain electromagnetic clocks, magneto telephones, antique radios, railroad depot equipment, and other historic devices. Whether you're restoring your grandfather's Seth Thomas self-winding clock, keeping a hand-crank magneto telephone operational, or powering vintage communication equipment, the EN6 delivers the authentic 1.5V power these devices were designed to use.
Exceptional Longevity and Value
Real-world performance speaks volumes: customers report 4+ years of continuous operation powering electromagnetic clocks—some batteries lasting over 54 months before replacement. This exceptional lifespan translates to outstanding value, with some users calculating less than $15 per year to keep their treasured antiques running. The 200Ah capacity provides ample energy reserves for low-voltage, high-power applications, while the long shelf life makes these batteries ideal as emergency power supplies or for seasonal equipment. Unlike vintage batteries that were prone to leaking and corrosion, modern zinc air alkaline chemistry eliminates dangerous liquids and maintains stable performance throughout its service life.
Modern Reliability, Classic Compatibility
Made in Spain by Cegasa, the EN6 features superior modern construction with a durable plastic case that far outlasts the paper-covered Eveready "Ignitor" batteries from the 1960s. The rugged housing protects against moisture, impacts, and handling while maintaining the authentic No. 6 dimensions (6.02" height, 2.54" diameter) and terminal configuration required for vintage equipment. The battery operates reliably in any position—upright, sideways, or even inverted—making it suitable for equipment that moves or vibrates during operation, such as railway applications or portable communication devices.
Wide Compatibility and Easy Installation
The EN6 replaces numerous historic battery designations including R40, LR40, 906, EN6S, BA23, and many others used across different manufacturers and applications. Compatible with self-winding clocks from Seth Thomas and other makers, Western Union telegraph equipment, hand-crank magneto telephones, vintage radios, navigation markers, railway lighting systems, coal mining lamps, and communication equipment from the early-to-mid 20th century. For easy wire connections in science experiments, hobby applications, antique toy trains, and special projects, add Fahnestock clips (sold separately) to safely attach bare wire without soldering. Maintenance-free design means simply install the battery and enjoy years of reliable power—no periodic maintenance, refilling, or special care required.
Pro Tip for Collectors
Since EN6 batteries can last over half a decade, it's easy to forget installation dates. Write the installation date directly on the plastic casing with a permanent marker for easy reference. Even though these batteries are leak-resistant, we recommend checking them once a year—daylight savings time makes a perfect reminder. This simple annual inspection habit helps antique collectors ensure their treasured equipment stays protected and operational for years to come.
Frequently Asked Questions

This is especially useful for hobby applications, science experiments, antique toy trains, and restoration projects.
Q: Will this work in my Seth Thomas self-winding clock?
A: Yes! The EN6 is the correct replacement for Seth Thomas electromagnetic clocks and other self-winding clock mechanisms that originally used No. 6 batteries. Most Seth Thomas models require two batteries. Customers report excellent performance with clocks dating back to the 1920s-1960s.
Q: What does this battery replace?
A: The EN6 replaces numerous vintage battery designations including Eveready "Ignitor" batteries, R40, LR40, 906, 906AC, EN6S, BA23, and many others. If your vintage equipment originally used a No. 6 dry cell, 6 volt ignition battery, or any of the cross-referenced part numbers, the EN6 is the correct modern replacement.
Q: Does this battery need to be charged or maintained?
A: No. The EN6 is a primary (non-rechargeable) battery that's ready to use immediately out of the box. It requires no charging, refilling, or periodic maintenance—simply install it and it will provide years of reliable power.
Q: Why is the EN6 better than old paper-covered batteries?
A: Modern EN6 batteries feature durable plastic housing that's far superior to the paper-covered Eveready batteries from the 1960s. The plastic case provides better protection against moisture, handling damage, and environmental conditions, while the advanced zinc air alkaline chemistry eliminates the leaking problems common in vintage batteries.
Q: How much does it cost to run my vintage clock with these batteries?
A: Based on customer experiences, if you use two EN6 batteries in a clock and they last 4-5 years, your annual cost is approximately $12-15 per year. This represents exceptional value for keeping treasured antique equipment operational.
Q: How can I keep track of when to replace my EN6 battery?
A: Since these batteries can last over half a decade, it's easy to forget when you installed them. We recommend writing the installation date on the side of the plastic casing with a permanent marker. Even though the EN6 is leak-resistant, checking your batteries once a year during daylight savings time is a great habit for any antique collector. This simple routine helps ensure your vintage equipment stays protected and operational.

Customer Reviews
Great product, fast service!
The new Cegasa EN6 1.5 volt battery is doing a fine job of powering my 87 year old BUllE electromagnetic clock.
I had to do a restoration on my clock, and the Cegasa EN6 battery should power the clock for 6 or more years!
I use these to power a Seth Thomas clock. The clock is weight-driven and square-cased and was used in railroad depots. It is electromagnetically wound and uses two of these to energize a very large electromagnet to lift the weight. This battery's plastic case is much better than the '60s-era Eveready paper-covered version.
So in November of 2013 I wrote a review of this battery. I had to purchase two of them for an old Seth Thomas self winding clock that had belonged to my grandfather. Well guess what? The batteries just died this week. So that's 4 years and 6 months of life from these! Not sure what the price was then but even at todays price that's a little less that $15 a year for two batteries for 4 years and 6 months! Seriously, where can you find such a value as this nowadays?
Works just fine in my old hand-crank magneto telephones. I'm ordering two more because I just got another old telephone.
I've had this square-cased Seth Thomas clock for decades. It was part of my Dad's collection. It required two (2) Eveready "Ignitor" 1.5V dry cells to keep it going. Those went out of production long ago and I have been unable to find a suitable replacement until now. These EN6 batteries have the Seth Thomas running and "KERCHUNKing" again. A bit pricey, but if they last the 18 months I used t
I have an old 1922 Self-winding clock that my father had hanging in the Western Union in Santa Barbara, CA. It is a beautiful clock and works perfect. It requires batteries to run and these are a perfect fit and quality for this clock. It winds itself each hour and the batteries have never let us down.
Thank you for your great Customer Service.
