Delta 12V 26AH Battery

Sealed Lead-Acid (VRLA) Technology: The Delta 12V 26AH 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 compatibility with a wide range of electronic applications, including UPS systems, solar charge controllers, inverters, security systems, and mobility devices, making it a versatile power solution.
Substantial Capacity: Provides a 26 Ampere-Hour (AH) capacity (typically at 10HR rate, ~28AH at 20HR rate), delivering a reliable energy reserve for longer runtimes or moderate power demands in applications like small UPS systems, security systems, 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 (horizontal, vertical, or side) 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) 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 medical facilities or data centers.
Shock and Vibration Resistant: Built with a robust, flame-retardant ABS plastic casing (UL94-V0 rated), 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 (Faston) or nut-and-bolt terminals (based on similar models like Delta HR 12-28 or Mighty Max ML28-12), providing sturdy, high-current connections for applications such as UPS systems, inverters, or solar setups, ensuring secure and reliable connectivity.
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), 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 7.8–10.4A (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 166 x 175 x 125 mm (L x W x H, based on similar models like Delta HR 12-28 or Mighty Max ML28-12) and weighs around 8–9 kg, 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 RoHS, ensuring compliance with international safety and performance standards, backed by Delta’s reputation for quality.
