Voltan 12V-45AH UPS Battery

Voltan 12V-45AH UPS Battery in Bangladesh

The Voltan 12V-45AH UPS Battery is an industrial-grade sealed lead-acid power solution engineered to deliver sustained, high-current backup during extended power outages. Built with a higher reserve capacity than standard desktop backup batteries, this 45-Ampere-Hour unit supports online servers, security command centers, optical fiber hubs, and multi-station IT setups.

Whether configuring a long-runtime battery bank for 3KVA to 10KVA online UPS units, providing emergency power to surveillance arrays, or backing up critical commercial equipment, Voltan delivers reliable electrical output. Manufactured with precision grid technology, it acts as a direct-replacement or expansion energy cell designed to prevent hard system shutdowns and preserve hardware longevity.

VRLA & AGM Technology: Leak-Proof and Maintenance-Free

The structural framework of the Voltan 12V-45AH battery uses Valve-Regulated Lead-Acid (VRLA) technology with Absorbent Glass Mat (AGM) internal separators. The liquid electrolyte is fully bound within high-porosity glass fiber micro-mats placed between lead plates.

This sealed AGM design provides essential operational benefits:

• Maintenance-Free Operation: Internal gas recombination efficiency exceeds 99%, eliminating electrolyte loss and removing the need for periodic water refilling.

• Spill-Proof Installation: The non-spillable construction prevents acid leaks, enabling flexible placement within server racks or specialized battery enclosures.

• Safety Valve Pressure System: Integrated safety release valves automatically vent excess internal gas during unintended overcharging and reseal to protect casing integrity.

Ultra-Low Internal Resistance & High-Surge Discharge

Electrical transmission efficiency depends heavily on low internal resistance. The Voltan 12V-45AH battery maintains a low internal resistance (approx. 8.5mΩ when fully charged at 25°C), reducing thermal heat generation during heavy energy draw.

With a 45Ah nominal capacity (measured at the 10-hour discharge rate to 10.8V cut-off), this model offers reliable discharge duration for high-wattage loads. When high-draw equipment initializes, the battery handles high current demand, delivering a 400A maximum discharge current for up to 5 seconds without voltage collapse.

Wide Thermal Range, Low Self-Discharge, and Fast Charge Acceptance

High ambient temperatures in local utility spaces can accelerate grid degradation. The Voltan 12V-45AH battery operates reliably across demanding thermal ranges:

• Discharge Range: -15°C to 50°C

• Charge Range: -10°C to 50°C

• Storage Range: -20°C to 50°C

Its lead-calcium tin alloy grid limits self-discharge during idle periods. Stored at 25°C, the unit retains 91% capacity after 3 months, 82% after 6 months, and 65% after 12 months. Supporting up to a 12A maximum charging current, it enables rapid energy recovery between frequent power cuts.

Industrial Versatility & Conductive Copper Terminals

Encased in a high-impact ABS resin housing, the battery resists mechanical shock and structural deformation. Standard high-conductivity copper terminals (T4/T9) reduce contact resistance and prevent terminal overheating during continuous load delivery.

Physical Specifications:

• Length: 200mm (±2mm) / 7.87 inches

• Width: 168mm (±2mm) / 6.61 inches

• Height / Total Height: 180mm (±2mm) / 7.07 inches

• Approximate Weight: ~12.3 kg (27.11 lbs) ±4%

Real-Life Usage Scenarios in Bangladesh

1. Server Rooms & Corporate Data Center Backup

Network servers, local database units, and NAS storage units require continuous power to prevent database corruption. Installing Voltan 12V-45AH batteries in an online UPS rack provides the runtime needed to bridge extended outages or execute graceful automated server shutdowns.

2. Commercial Surveillance & Access Control Systems

Security setups in commercial buildings, banking outlets, and retail centers rely on steady DC power. The 45Ah capacity sustains continuous recording feeds across multi-channel NVR/DVR arrays, biometric locks, and alarm monitoring panels during utility blackouts.

3. ISP Fiber Network Switches & Telecom Hubs

Local Internet Service Providers and corporate network racks require uninterrupted power to keep fiber equipment live. Deployed in central DC backup setups, this battery keeps optical fiber switches and core routers online continuously.
