The DEL-S12V18F3 Deltec AGM Battery is a heavy-duty, high-capacity 12V power unit meticulously engineered to offer exceptional backup and deep-cycle stamina across critical standby systems, uninterruptible power supplies (UPS), and demanding leisure layouts. Produced in a state-of-the-art manufacturing facility, this Valve Regulated Lead Acid (VRLA) battery completely locks its acid electrolyte within ultra-durable fine glass mat separators to guarantee a completely leak-proof, maintenance-free profile. Combining extra-heavy plates with high-density active material, it delivers exceptional structural longevity and consistent cyclic discharge performance to satisfy critical infrastructure and mobile auxiliary configurations across Australia and New Zealand.
Perfect for operators who demand:
- ✓ High-capacity 18Ah delivery to support extended standby backup runtimes in enterprise UPS rigs, fire control panels, and intricate security grids
- ✓ Robust c20 deep-cycle stability built to handle moderate to heavy house loads in off-road, marine, and leisure fields
- ✓ Compliance with rigorous local standards featuring fire-retardant casing layouts and integrated safety flame arresters
Key Features & Benefits
Advanced Standby & Cyclic AGM
- • Absorbent Glass Mat architecture absorbs acid entirely to ensure flexible, multi-angle mounting profiles
- • Purpose-built to sustain consistent cyclic routines without suffering early capacity fade over time
- • Gas recombinant structural engineering achieves completely self-contained, maintenance-free handling
Heavy-Duty Grid Armour
- • Formulated with thicker, heavier internal plates to secure stable current delivery under cyclic strain
- • Loaded with premium high-density active materials to extend structural lifecycle bounds
- • Advanced lead alloy composition delivers exceptional prevention against internal corrosion pathways
Elite Safety Engineering
- • Valve Regulated Lead Acid (VRLA) pressure vents strictly manage internal compression limits
- • Encased in a premium, highly durable fire-retardant outer housing structure
- • Factory-fitted safety flame arresters guard internal cells from external ignition risks
Rugged Environmental Endurance
- • High vibration-resistant chassis structure shields cells from hard impacts on regional lines
- • Designed to successfully counter extreme structural decay parameters across idle periods
- • Fully optimised to function smoothly under volatile regional climate variations
Advantages & Considerations
Advantages
- ✓ Substantial 18Ah rating delivers significant runtime compared to lower-capacity blocks
- ✓ VRLA gas-recombinant engineering removes corrosive venting risk and water top-ups entirely
- ✓ Fully compliant with local fire and security safety metrics utilizing fire-retardant outer housing
- ✓ Thicker heavy plate configuration ensures steady power delivery and extended operational service life
Considerations
- • Features standard thread/nut style F3 terminals; verify wiring connectors accommodate this terminal configuration
- • Ensure battery box clearances properly accept the taller 181 x 167 mm physical dimensions
- • Long-term storage health necessitates connecting to an AGM-calibrated smart charger periodically
Frequently Asked Questions
What is the lifespan of this battery?
In dedicated standby backup or emergency systems centre routines, this model typically delivers an operational service life of 3 to 5 years. In active, deep cyclic configurations, the total lifespan parameters are directly governed by discharge depth levels, cycle frequency, and ambient temperatures.
Is this battery maintenance-free?
Yes, it features a completely Sealed Maintenance-Free (SMF) recombinant design. The internal acid electrolyte is fully captured within specialised fine glass mat separators, meaning liquid vapour cannot escape, and you never need to perform fluid top-ups.
What systems/applications is this battery compatible with?
The Deltec DEL-S12V18F3 is heavily used across critical standby equipment centre lines. This includes high-draw emergency lighting networks, fire control enclosures, main security alarm stations, server UPS units, and deep-cycle accessories on rugged leisure craft or portable gear.
How should I store this battery during the off-season?
Store the battery cell inside a clean, dry, and cool storage area isolated from direct environmental extremes. Ensure it is charged up entirely before leaving it idle, and use an AGM-compatible smart storage unit to maintain internal voltage values.
What is covered under the warranty?
This high-performance battery includes a dedicated manufacturer's standby and cyclic warranty. It covers unexpected operational failures resulting directly from structural material defects or assembly faults under standard operating parameters.
