Voltan 12V-18AH UPS Battery

Voltan 12V-18AH UPS Battery in Bangladesh

The Voltan 12V-18AH UPS Battery is a high-reserve energy cell designed to provide prolonged, unwavering power backup during severe electrical disruptions. Stepping well beyond standard low-capacity batteries, this heavy-duty 18-Ampere-Hour unit offers the substantial power storage needed to support high-draw desktop workstations, multi-channel security arrays, network server racks, and sensitive medical equipment across Bangladesh.

Whether you are safeguarding professional creative rigs, maintaining continuous multi-camera CCTV recording in a retail center, or keeping enterprise-grade fiber network switches online, Voltan delivers rock-solid, uninterrupted DC energy. Engineered with advanced sealed lead-acid technology, it serves as a high-capacity replacement or external bank cell that elevates your backup system's overall reliability.

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

At the core of the Voltan 12V-18AH battery is Valve-Regulated Lead-Acid (VRLA) technology coupled with fine Absorbent Glass Mat (AGM) internal separators. Liquid electrolyte is fully absorbed within high-porosity glass fiber micro-mats positioned between lead plates.

This advanced architecture provides three essential user benefits:

1. Zero Electrolyte Maintenance: Over 99% of internal gas generated during normal charging is recombined internally, eliminating water loss and removing the hassle of liquid top-ups.

2. Spill-Proof & Flexible Mounting: Being thoroughly sealed, the battery eliminates acid leakage risks, allowing safe operation in various orientations inside server cabinets or UPS battery trays.

3. Automatic Pressure Relief System: Built-in low-pressure safety vents automatically discharge excess gas during unexpected overcharge conditions and reseal instantly to maintain internal structural safety.

Heavy High-Rate Discharge Capabilities & Ultra-Low Resistance

Electrical efficiency depends heavily on low internal resistance. The Voltan 12V-18AH battery features an exceptionally low internal resistance of approximately 16mΩ when fully charged at 25°C. This low resistance minimizes thermal energy loss, prevents internal overheating, and optimizes current delivery under heavy demands.

With a nominal 18AH capacity (at the 20-hour rate), this battery delivers up to 2.4 times the backup duration of standard 7.5AH cells under identical hardware loads. When high-draw devices power on or experience sudden load spikes, the battery easily delivers a massive 270 Amperes of maximum discharge current for 5 seconds. This high discharge capability prevents premature low-voltage cutoffs and handles heavy hardware inrush currents smoothly.

Excellent Temperature Adaptability and Low Self-Discharge

In Bangladesh, high ambient summer temperatures can strain power storage systems. The Voltan 12V-18AH battery is built to perform in challenging environments across a broad temperature 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. When stored at 25°C, it retains approximately 91% capacity after 3 months, 82% after 6 months, and 65% after 12 months. Supporting a maximum charging current of 5.4A, the battery accepts rapid energy recovery between frequent load-shedding cycles.

Multi-Industry Application Versatility

While deployed extensively in high-capacity desktop UPS systems, the Voltan 12V-18AH battery serves as a versatile DC power source across various setup types:

• High-Capacity UPS Systems: Ideal for 1200VA, 1500VA, and 2000VA online and offline UPS units.

• Security & Access Control: Powers 16-channel and 32-channel CCTV DVRs/NVRs, magnetic locks, and central alarm panels.

• Telecommunications & Networking: Keeps network server racks, core switches, and high-power routers running during prolonged blackouts.

• Medical Devices & Solar Backups: Provides stable DC backup for portable medical monitors, emergency lighting, and solar array systems.

Robust ABS Construction & High-Conductivity Copper Terminals

Encased in a heavy-duty, flame-retardant ABS resin shell, the battery resists mechanical shock, severe vibration, and thermal expansion. High-grade T3/T8 copper terminals provide maximum electrical conductivity and low contact resistance, preventing terminal heating during continuous high-amperage discharge.

Physical Specifications:

• Length: 181mm (±2mm)

• Width: 77mm (±1mm)

• Height / Total Height: 167mm (±2mm)

• Approximate Weight: ~5.20 kg (11.46 lbs)

Real-Life Usage Scenarios in Bangladesh

1. Professional Multi-Monitor Workstations & Video Editing Suites

Video editors, 3D animators, and software engineers run multi-monitor setups with high-wattage power supplies that drain small UPS batteries almost instantly. Upgrading to an 18AH Voltan cell provides the critical backup window needed to save large project timelines, render files, and perform a controlled system shutdown.

2. Commercial CCTV & Security Operations

For retail hubs, banks, and office buildings across Dhaka, losing security camera power creates immediate vulnerabilities. Installed in a central backup system, the Voltan 12V-18AH battery delivers continuous DC power to keep DVR recording feeds active through long load-shedding cycles.

3. Enterprise Networking & Remote IT Support

IT administrators and remote freelancers depend on continuous fiber internet during client calls and data transfers. Connected to DC UPS systems or network power supplies, this battery keeps switches, routers, and ONUs running reliably through extended power outages.
