Delta 12V 18AH Battery

Sealed Lead-Acid (VRLA) Technology: The Delta 12V 18AH Battery employs valve-regulated lead-acid (VRLA) technology with Absorbent Glass Mat (AGM) construction, providing maintenance-free, spill-proof, and leak-proof operation, eliminating the need for water topping or electrolyte checks, ideal for hassle-free use in various settings.
Nominal Voltage: Features a standard 12V nominal voltage, ensuring wide compatibility with electronic devices and backup power systems, including UPS, solar charge controllers, inverters, security systems, and mobility devices, making it a versatile power solution.
Significant Capacity: Offers an 18 Ampere-Hour (AH) capacity (20HR rate at 10.5V, ~16.7AH at 10HR rate, ~11.7AH at 1HR rate), providing reliable energy storage for extended backup runtimes or moderate power demands in applications like small UPS systems, emergency lighting, and alarm systems.
Absorbent Glass Mat (AGM) Construction: Utilizes AGM technology, where the electrolyte is absorbed in a fiberglass mat, enabling flexible mounting in any orientation (except upside-down) and efficient gas recombination (up to 99%), enhancing safety and performance in confined spaces.
Low Self-Discharge Rate: Exhibits a self-discharge rate of approximately 1–3% per month at 25°C, allowing the battery to retain its charge during extended storage, ideal for seasonal or backup applications with minimal recharging needs.
Long Design Life: Engineered for a design life of 3–5 years in standby applications (e.g., UPS, security systems) or 300–500 cycles at 100% depth of discharge in cyclic use, with high-quality models (e.g., Delta HRL series) potentially extending to 6–8 years in optimal standby conditions.
Valve-Regulated Design: Incorporates a VRLA system with pressure relief valves to control internal gas pressure, minimizing gas emissions and ensuring safe operation in any orientation, suitable for sensitive environments like hospitals, data centers, or emergency 911 centers.
Shock and Vibration Resistant: Built with a rugged, flame-retardant ABS plastic casing (UL94-HB or UL94-V0), designed to withstand physical stresses, shocks, and vibrations, ensuring durability in rugged applications like mobility scooters, solar installations, or telecommunications.
F3 Terminal Type: Equipped with F3 (Nut and Bolt) terminals, providing sturdy, high-current connections for secure and reliable connectivity in applications such as UPS systems, inverters, or solar setups, with clear positive (+) and negative (-) markings for easy wiring.
Broad Application Range: Versatile for use in UPS systems, security systems, emergency lighting, solar and wind energy storage, telecommunication equipment, mobility devices (e.g., wheelchairs, scooters), fire detection systems, and various industrial applications, supporting both cyclic and standby operations.
High Discharge Performance: AGM construction enables higher discharge rates compared to GEL, making it ideal for applications requiring short bursts of high current, such as UPS or alarm systems, though with slightly lower deep cycle endurance than GEL variants.
High Charge Efficiency: Supports efficient charging with a recommended float voltage of 2.20–2.28V per cell (13.2–13.68V for 12V) and cycle voltage of 2.40–2.45V per cell (14.4–14.7V), with a maximum charge current of 5.4–7.2A (30% of capacity), compatible with standard chargers.
Wide Operating Temperature Range: Performs reliably from -15°C to +50°C (discharge: -20°C to +60°C, charge: -10°C to +60°C), with optimal performance at 20–25°C, though AGM models are less resilient in extreme high temperatures compared to GEL variants.
Compact Dimensions: Measures approximately 181 x 77 x 167 mm (L x W x H) and weighs around 5.3–5.6 kg (11.7–12.3 lbs), offering a compact, lightweight design for easy installation compared to higher-capacity models, though still requiring careful handling.
Warranty and Certifications: Typically includes a 1-year manufacturer’s warranty (extendable to 2–3 years in some regions), with certifications like CE, UL, ISO9001, and IATA/ICAO Special Provision A67 for air transport, ensuring compliance with international safety and performance standards.
