The Fullriver HC28 Advanced AGM Battery is a premium, ultra-compact dual-purpose power cell engineered to excel in elite Australian motorsports, performance racing, and demanding off-road applications. Moving far beyond generic starting options, this low-resistance powerhouse packs a massive punch, delivering 925 Peak Cranking Amps to ignite high-compression or race-tuned engines, while offering genuine deep-cycling capability. Wrapped in Fullriver's sleek, modern black chassis, the HC28 provides maximum electrical conductivity, exceptional recharge efficiency, and total non-spillable installation flexibility for tight spaces or custom cabin mounts.
Perfect for drivers who demand:
- ✓ High-current engine starting power optimised for high-performance vehicles and low-temperature cranking
- ✓ Extreme vibration armour built tough to handle continuous track corrugations, rally racing, and heavy shock
- ✓ A low-profile, space-saving design that can be safely mounted in almost any physical orientation
Key Features & Benefits
Dual-Purpose Cranking & Cycle Life
- • Fires a massive 925 peak cranking amps for reliable starting under extreme conditions
- • Heavy-duty, extra-thick grids deliver true cyclic stamina up to 1000 full life cycles at 50% DOD
- • Specially formulated proprietary active paste ensures exceptional recovery from deep discharges
Sealed Maintenance-Free Cover
- • Non-spillable and leak-proof AGM structure allows for installation in almost any direction
- • DOT, IATA, IMDG, and ICAO certified as non-hazardous for flexible, fuss-free transport
- • Fully sealed architecture সফলly limits evaporation, completely removing manual top-up needs
Electrical Stability & Conductivity
- • Solid brass terminals provide superior conductivity and maximum low-resistance current transmission
- • Highly porous micro-porous glass fibre separators guarantee significantly faster recharge acceptance
- • Long standby shelf life with an incredibly low self-discharge rate of less than 1% per month
Advanced Safety Systems
- • Special lead-calcium alloy grid plates protect internal cells against heavy charge currents
- • Self-regulating pressure relief valves safely mitigate gas build-up under intense thermal strain
- • Corrosion-resistant, rugged design absorbs kinetic road shock, protecting engine bay accessories
Advantages & Considerations
Advantages
- ✓ Hybrid design serves perfectly as a powerful starter and robust accessory battery
- ✓ Safe, corrosion-free layout is ideal for cockpit installations in custom motorsports
- ✓ Dependable 40-minute reserve capacity delivers an excellent electrical power buffer
- ✓ Low-profile sizing seamlessly solves extremely limited spacing constraints
Considerations
- • Compact 28 Ah capacity is fine-tuned for starting weight reduction, not large caravan living setups
- • Integrated M8 threaded posts may require terminal adaptors to hook up standard tapered clamps
- • Heavy commercial-grade internal lead structures result in a solid 10.70 kg weight density
Frequently Asked Questions
What is the lifespan of this battery?
The Fullriver HC28 is designed to outlast conventional wet-starting alternatives by combining high cranking current with genuine cyclic characteristics. Subject to proper multi-stage auxiliary charging routines and regular enthusiast use, it provides exceptional longevity and handles up to 1000 discharge cycles at 50% DOD.
Is this battery maintenance-free?
Yes, this battery features a completely Sealed Maintenance-Free (SMF) absorbed glass mat construction. Internal recombination prevents gas and liquid evaporation, meaning it will never leak, require water top-ups, or cause terminal corrosion.
What vehicles/applications is this battery compatible with?
The HC28 is highly optimised as a high-performance starting option for motorsports, racing vehicles, rally cars, classic vehicles, powersports, and modified four-wheel drives (4WD) requiring high power output, low internal resistance, and heavy vibration protection.
How should I store this battery during the off-season?
Store the battery in a cool, dry location, out of direct exposure to extreme temperatures. Thanks to its advanced ultra-low self-discharge layout, the HC28 loses less than 1% of its charge per month on standby. For best results, ensure it is fully charged before storage, and connect an AGM-compatible smart charger during extended downtime.
What is covered under the warranty?
The local warranty covers early structural, component, or operational failures arising directly from internal manufacturing errors or material defaults. It provides dependable, customer-centric protection when the product is used within regular guidelines in its intended performance, starting and auxiliary workloads.
