Product Description
The EnerSys Hawker Cyclon 0819-0024 is a 12-volt, 2.5Ah sealed lead acid battery assembly built on EnerSys's trusted Cyclon pure lead AGM platform. If you're looking for a direct replacement with the right connector already attached, this is it. The 0819-0024 comes factory-assembled with a plug harness, so installation is straightforward — no adapters, no guesswork.
Pure Lead AGM Technology You Can Count On
The Cyclon line has been around since 1973 and has earned a reputation for outlasting conventional sealed lead acid batteries. The secret is in the construction: pure lead-tin cylindrical cells wrapped in absorbed glass mat (AGM) technology. This combination delivers better power density, faster recharge capability, and significantly more charge/discharge cycles than standard SLA designs. Fewer replacements means less hassle over time.
The 0819-0024 is built in EnerSys's signature 2x3 monobloc configuration — six D-size cells arranged in two rows of three, all housed in a compact, rigid enclosure. This layout keeps the footprint small while maintaining the full 12-volt output your equipment needs.
Maintenance-Free and Ready to Work
One of the biggest advantages of the Cyclon design is that it requires zero maintenance. The sealed construction means there's nothing to check, fill, or adjust. It's also non-spillable, so orientation isn't a concern — this battery can be mounted in virtually any position without issue. A built-in safety valve handles any pressure fluctuations internally, keeping everything safe and self-contained.

Frequently Asked Questions
What equipment does the EnerSys Hawker Cyclon 0819-0024 fit?
This battery is a known replacement for Lawn-Boy and Toro lawn equipment, among other applications. The plug harness connector is what sets this specific assembly apart from other Cyclon 12V 2.5Ah configurations. If you're unsure whether it fits your equipment, compare the connector type and dimensions (4.48" x 3.52" x 2.77") against your current battery before ordering.
What does the plug harness connector mean?
It means the battery ships with a wiring harness already attached, designed to plug directly into your equipment's existing connector. This makes replacement quick and clean — no loose terminals to connect or tools required for the hookup itself.
How is this different from other EnerSys Cyclon 12V 2.5Ah batteries?
The Cyclon line includes several 12V 2.5Ah assemblies that share the same 2x3 monobloc cell configuration but differ in their connector type. The 0819-0024 specifically features a plug harness, while other assemblies in the same family use blade-style terminals or other connection styles. Always match the part number and connector type to your application.
Is this battery safe to ship and store?
Yes. The 0819-0024 is sealed and non-spillable, which qualifies it for standard shipping. EnerSys recommends recharging within 24 months of the manufacture date if the battery has been in storage. Once in use, normal charge cycles will keep it in good working condition.
Does this battery require any special charger?
The 0819-0024 is designed to work with standard 12-volt sealed lead acid chargers. For best results and longest life, use a charger matched to AGM or sealed lead acid chemistry and avoid overcharging. If your equipment has an onboard charging system, it's typically already compatible.
