Voltan 12V-40AH UPS Battery

Voltan 12V-40AH UPS Battery in Bangladesh

The Voltan 12V-40AH UPS Battery is an industrial-grade, high-capacity sealed lead-acid battery engineered to provide extended energy backup during prolonged electrical outages. Designed to far exceed standard desktop-class backup cells, this heavy-duty 40-Ampere-Hour unit offers the substantial power storage needed to run online server banks, multi-station IT environments, medical monitoring equipment, and extensive CCTV security setups smoothly across Bangladesh.

Whether you are protecting enterprise server racks, sustaining continuous power for telecommunication hubs, or establishing a reliable high-capacity battery bank for a 3KVA to 10KVA UPS system, Voltan delivers rock-solid electrical output. Manufactured with precision engineering, it acts as a premium direct-replacement or expansion energy cell that elevates operational uptime and protects sensitive hardware from hard shutdowns.

Advanced VRLA & AGM Architecture: Spill-Proof and Maintenance-Free

The foundation of the Voltan 12V-40AH battery relies on Valve-Regulated Lead-Acid (VRLA) technology coupled with fine Absorbent Glass Mat (AGM) internal separators. The liquid electrolyte is fully absorbed within high-porosity glass fiber micro-mats positioned between robust lead plates.

This sealed engineering delivers key operational advantages:

• 100% Maintenance-Free: Internal gas recombination technology recombines over 99% of generated gases, removing liquid loss and completely eliminating the need for periodic distilled water top-ups.

• Leak-Proof Safety: The non-spillable AGM construction prevents acid leaks, allowing safe installation in various orientations inside server racks or specialized battery cabinets.

• Automatic Pressure Regulation: Integrated low-pressure safety release valves vent excess gas during unexpected overcharging and reseal automatically to preserve internal structural safety.

Low Internal Resistance & High-Current Surge Discharge Capability

Electrical current transfer efficiency is dictated by internal resistance. The Voltan 12V-40AH battery features an exceptionally low internal resistance of approximately 8.5mΩ when fully charged at 25°C. This ultra-low resistance minimizes internal thermal heat buildup under heavy current draw, maximizing output efficiency and extending usable battery runtime.

With a nominal capacity of 40Ah (at the 10-hour discharge rate to 10.8V), this cell delivers substantial runtime for high-wattage equipment. When heavy machinery or high-draw server hardware initializes, the battery handles high surge demands smoothly, delivering a massive 400 Amperes of maximum discharge current for 5 seconds without triggering low-voltage UPS alarms.

Thermal Endurance, Low Self-Discharge, and Fast Recharge

In Bangladesh, high ambient summer temperatures inside non-air-conditioned utility rooms can accelerate battery wear. The Voltan 12V-40AH battery is built to perform in challenging environmental conditions across a broad operational range:

• Discharge Temperature: -15°C to 50°C

• Charge Temperature: -10°C to 50°C

• Storage Temperature: -20°C to 50°C

Its lead-calcium tin alloy grid composition suppresses self-discharge rates during idle standby periods. Stored at 25°C, the battery retains 91% capacity after 3 months, 82% after 6 months, and 65% after 12 months. Supporting a maximum charging current of 12A, it accepts rapid energy recovery between frequent load-shedding cycles.

Multi-Industry Application Versatility

While deployed extensively in high-capacity UPS setups, the Voltan 12V-40AH battery serves as a versatile DC power source across various commercial and industrial fields:

• High-Capacity UPS Systems: Ideal for 3KVA, 6KVA, and 10KVA online and offline UPS units requiring high-reserve battery banks.

• Commercial CCTV & Access Control: Powers 32-channel and 64-channel DVR/NVR setups, biometrics, and security monitoring centers continuously.

• Telecommunications & Data Networks: Keeps core fiber switches, base transceiver stations, and server racks active during extended grid outages.

• Medical Equipment & Solar Storage: Delivers stable DC backup for diagnostic equipment, emergency lighting, and solar power storage arrays.

Heavy-Duty Shell & Conductive Copper Terminals

Protected by a high-impact, flame-retardant ABS resin casing, the battery resists mechanical shocks, physical impacts, and thermal expansion. High-purity T4/T9 copper terminals provide maximum electrical conductivity and low contact resistance, preventing terminal heating during continuous high-amperage output.

Physical Specifications:
