Delta 12V 65AH Battery

Sealed Lead-Acid (VRLA) Technology: The Delta 12V 65AH 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 devices and systems, including inverters, solar charge controllers, UPS systems, and telecommunications equipment, making it a versatile power solution.
High Capacity: Provides a 65 Ampere-Hour (AH) capacity (10HR rate at 10.8V, ~68AH at 20HR rate), delivering substantial energy storage for significant backup runtimes or high-power demands in applications like UPS, solar systems, and emergency lighting.
Absorbent Glass Mat (AGM) Construction: Utilizes AGM technology, where the electrolyte is absorbed in a fiberglass mat, enabling flexible mounting orientations (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 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) or 300–500 cycles at 100% depth of discharge in cyclic use, with high-quality models (e.g., Delta HRL series) potentially reaching 10–12 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 data centers or medical facilities.
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 solar installations, marine, or RV use.
Terminal Type: Equipped with M6 screw or insert terminals (based on similar models like TLV12650FR-M6), providing secure, high-current connections for heavy-duty applications such as inverters, UPS systems, or solar setups.
Broad Application Range: Versatile for use in large UPS systems, solar and wind energy storage, telecommunication equipment, security systems, emergency lighting, medical devices, and mobility 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 19.5–26A, 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 350 x 167 x 179 mm (L x W x H, based on similar models like TLV12650FR-M6) and weighs around 23.6 kg (52 lbs), balancing capacity with manageable installation, though its weight requires careful handling.
Warranty and Certifications: Typically includes a 1-year manufacturer’s warranty (extendable to 3 years in some cases), with certifications like CE, UL, and VdS, ensuring compliance with international safety and performance standards, backed by Delta’s reputation for quality.
