EnerSys Cyclon 0810-0102M Battery Assembly – 6V, 2.5Ah

When your equipment can't afford to fail, you need a battery that's been built to a higher standard. The EnerSys Cyclon 0810-0102M is a 6-volt, 2.5Ah sealed lead acid battery assembly made up of three D-size Cyclon cells wired in series and wrapped in a protective black heat shrink sleeve. It's assembled right here in the USA and engineered for high-reliability applications where long service life, consistent power delivery, and rugged construction aren't optional — they're required.

The Technology Behind the Cyclon

EnerSys Cyclon batteries have a history going back to 1973, when the Gates Corporation pioneered the sealed pure-lead cell. Since then, the technology has evolved through Hawker Energy and ultimately into EnerSys, the world's largest industrial battery manufacturer. What's never changed is the core design philosophy: build a battery that outperforms and outlasts conventional sealed lead acid alternatives.

Each cell inside this assembly uses 99.99% pure lead plates in a patented spiral (wound) design, housed within a steel canister. That combination is what gives Cyclon batteries their edge. The thin pure-lead plates create more surface area than standard lead-calcium designs, which translates directly to higher power output, faster recharge, and a much longer service life. High-purity electrolyte is absorbed into an AGM (Absorbent Glass Mat) separator, making the battery fully sealed, leak-proof, and safe to operate in any orientation.

Built to Last — and Built to Work Hard

The 0810-0102M carries an impressive 15-year design life at 68°F (20°C), and is capable of 300 or more full depth-of-discharge cycles. By comparison, many conventional sealed lead acid batteries top out around 200 cycles and a fraction of the standby life. This assembly is also rated for an operating temperature range from -85°F to +176°F (-65°C to +80°C), making it well-suited for environments that would compromise lesser batteries.

One of the more practical advantages is recharge speed. Thanks to the pure lead chemistry and low internal resistance, this battery can reach a 95% state of charge in under an hour — a significant benefit in applications where quick turnaround between uses matters.

Where the 0810-0102M Gets Used

The breadth of compatible equipment for this assembly speaks to its versatility. Common applications include:

• Emergency lighting systems (including units from Dual Lite and Emergi-Lite)
• Medical and clinical devices, such as enteral feeding pumps, portable blood coagulators, and patient scales
• Test and measurement equipment, including scales and portable instruments
• Security and life-safety systems
• Portable HP test equipment including the K2000, Portable 110, and Portable Plus series

It directly replaces part numbers 0810-0102 and 1420-0329, and is compatible with a wide range of OEM and third-party assemblies across the medical, industrial, and electronics industries.

Safe to Ship, Easy to Specify

This assembly is classified as non-hazardous and non-spillable, meaning it ships without the special packaging requirements that apply to many other battery chemistries. It meets UL 1989 and DOT non-spillable standards, and the resealable 50-PSI safety vent prevents gas buildup without risking electrolyte loss. The .187" (F1) quick-connect tab terminals make installation and replacement straightforward in most supported applications.
