Delta 12V 12AH Battery.

Sealed Lead-Acid (VRLA) Technology: The Delta 12V 12AH Battery employs valve-regulated lead-acid (VRLA) technology with Absorbent Glass Mat (AGM) construction, offering maintenance-free, spill-proof, and leak-proof operation, eliminating the need for electrolyte checks or water topping, ideal for hassle-free use.
Nominal Voltage: Features a standard 12V nominal voltage, ensuring broad compatibility with a wide array of electronic devices, including UPS systems, solar charge controllers, inverters, security systems, and portable devices, making it a versatile power solution.
Substantial Capacity: Provides a 12 Ampere-Hour (AH) capacity (typically at 20HR rate, ~11.5AH at 10HR rate, ~8AH at 1HR rate), delivering reliable energy storage for longer backup durations or moderate power demands in applications like small UPS systems, security alarms, and emergency lighting.
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 requirements.
Long Design Life: Engineered for a design life of 3–5 years in standby applications (e.g., UPS, security systems), with some DTM series models (e.g., DTM 12-12) extending to 6 years in optimal standby conditions, or 300–500 cycles at 100% depth of discharge in cyclic use.
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 robust, 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 devices, solar installations, or telecommunications.
F2 Terminal Type: Equipped with F2 (Faston, 0.250-inch) terminals, providing widely compatible, sturdy connections for straightforward installation in applications such as UPS systems, inverters, or security alarms, with clear positive (+) and negative (-) markings for easy wiring.
Broad Application Range: Versatile for use in UPS systems, security alarms, emergency lighting, medical equipment (e.g., portable ventilators), telecommunication systems, mobility devices (e.g., wheelchairs), and various portable devices, 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 3.6–4.8A (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 151 x 98 x 95 mm (L x W x H, based on similar models like Delta DTM 12-12 or Mighty Max ML12-12) and weighs around 3.8–4.2 kg (8.4–9.3 lbs), offering a compact, lightweight design for easy installation in tight spaces.
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, RoHS, and IATA/ICAO Special Provision A67 for air transport, ensuring compliance with international safety and performance standards.
