Voltan 12V-65AH UPS Battery

Voltan 12V-65AH UPS Battery in Bangladesh

The Voltan 12V-65AH UPS Battery is a high-capacity, industrial-grade sealed lead-acid energy reserve engineered to deliver steady DC power during extended blackouts. Built with a heavy-duty 65-Ampere-Hour capacity rating, this cell exceeds the capacity of standard desktop batteries, making it an ideal choice for high-draw online UPS systems, network switches, surveillance racks, and telecommunications infrastructure.

Whether you are configuring a extended-runtime battery bank for 3KVA, 6KVA, or 10KVA online UPS units or providing emergency backup for critical security infrastructure, Voltan delivers dependable electrical stability. Its precision lead-plate construction provides consistent voltage discharge, protecting sensitive microprocessors from unexpected shutdowns, brownouts, and power interruptions.

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

The Voltan 12V-65AH battery is engineered around Valve-Regulated Lead-Acid (VRLA) technology coupled with high-porosity Absorbent Glass Mat (AGM) internal separators. Rather than relying on free liquid acid, the electrolyte is fully absorbed into fine glass fiber mats positioned between heavy lead plates.

This advanced architecture offers significant operational benefits:

• Zero Fluid Maintenance: Over 99% internal gas recombination efficiency recombines hydrogen and oxygen gases back into water, eliminating fluid loss and removing the need for periodic distilled water top-ups.

• Spill-Proof Structural Safety: Non-spillable AGM construction prevents acid leaks, enabling safe operation in battery cabinets or server racks.

• Automatic Safety Relief Valves: Integrated low-pressure safety release valves automatically vent excess internal gases during unexpected overcharging and reseal automatically to maintain casing structural safety.

Low Internal Resistance & High Surge Current Capability

Internal resistance directly affects current transfer efficiency and operational heat buildup. The Voltan 12V-65AH battery features a very low internal resistance of approximately 6.5mΩ when fully charged at 25°C. This ultra-low resistance ensures high power discharge efficiency while minimizing internal thermal heat buildup under heavy electrical loads.

With a nominal 10-hour capacity of 65Ah (discharging to a 10.8V cutoff), this unit provides long-duration energy storage. For high-draw server hardware and inductive motor startup demands, the battery handles initial current surges smoothly, delivering a maximum discharge current of 700 Amperes for up to 5 seconds without voltage collapse.

Thermal Endurance, Low Self-Discharge, and Rapid Recharge

High ambient temperatures in Bangladesh's non-air-conditioned utility rooms can accelerate battery grid degradation. The Voltan 12V-65AH battery is built to perform in challenging environmental conditions:

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

• Charge Temperature: -10°C to 50°C

• Storage Temperature: -20°C to 50°C

Formulated with corrosion-resistant lead-calcium tin alloy grids, it suppresses self-discharge rates during idle storage. When 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 21A, it enables fast energy recovery between frequent load-shedding cycles.

Durable ABS Casing & High-Conductivity Copper Terminals

Encased in a high-impact, fire-resistant ABS resin casing, the battery resists mechanical vibration, physical shock, and thermal stress. Heavy-duty T5/T9 copper terminals provide maximum electrical conductivity and low contact resistance, reducing terminal overheating during high-amperage output.

Physical Specifications:

• Length: 360mm (±2mm) / 14.17 inches

• Width: 175mm (±2mm) / 6.89 inches

• Height: 200mm (±2mm) / 7.87 inches

• Total Height: T5: 222mm (±2mm) | T9: 200mm (±2mm)

• Approximate Weight: ~19.5 kg (43.0 lbs) ±4%

Real-Life Usage Scenarios in Bangladesh

1. Data Centers & Enterprise Server Racks

Corporate database networks, local cloud servers, and high-performance network storage units require constant electrical input to prevent database corruption during sudden utility loss. Deployed in a multi-battery series bank, Voltan 12V-65AH units provide the extended runtime required to maintain operations through prolonged load-shedding or execute safe automated network shutdowns.

2. ISP Infrastructure & Telecommunication Hubs

Local Internet Service Providers and telecommunications nodes require continuous DC power to keep fiber terminals, optical switches, and core network routers live. This high-capacity cell provides uninterrupted energy storage to maintain core network uptime during utility blackouts.

3. High-Capacity Commercial CCTV & Security Setup

Commercial facilities, financial institutions, and manufacturing plants running 64-channel NVR arrays, active monitoring consoles, and biometric access controls depend on continuous power. The 65Ah reserve capacity keeps security systems recording throughout power cuts.
