Voltan 12V-26AH UPS Battery

Voltan 12V-26AH UPS Battery in Bangladesh

The Voltan 12V-26AH UPS Battery is engineered as a heavy-duty, high-capacity energy cell built to deliver extended runtime and robust voltage stability during severe power disruptions. Going beyond standard desktop-class backup batteries, this 26-Ampere-Hour power reservoir supplies the substantial energy required to run high-load servers, multi-terminal IT centers, multi-channel security arrays, and sensitive medical instruments smoothly across Bangladesh.

Whether you are supporting a commercial data hub, maintaining continuous 24/7 CCTV security recording, or ensuring uninterrupted power for medical and networking hardware, Voltan delivers rock-solid, reliable energy. Built with advanced sealed lead-acid technology, it functions as a high-performance replacement battery or external battery bank component that elevates the standby duration and overall dependability of high-capacity offline and online UPS systems.

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

At the core of the Voltan 12V-26AH battery lies state-of-the-art Valve-Regulated Lead-Acid (VRLA) architecture paired with Absorbent Glass Mat (AGM) internal construction. The liquid electrolyte is completely immobilized inside fine, high-porosity micro-glass fiber mat separators positioned between lead plates.

This sealed engineering yields key operational advantages:

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

• Leak-Proof Safety: The non-spillable AGM design eliminates acid leaks, allowing safe installation in various orientations inside server enclosures or external battery cabinets.

• Integrated Pressure Protection: Built-in low-pressure safety release valves automatically vent excess gas during accidental overcharge states and reseal immediately to preserve structural integrity.

Ultra-Low Internal Resistance & Heavy Surge Discharge Performance

Electrical delivery efficiency is governed by internal resistance. The Voltan 12V-26AH battery features an exceptionally low internal resistance of approximately 12mΩ when fully charged at 25°C. This low internal resistance limits thermal energy buildup during operation, prevents internal overheating, and optimizes current output under heavy load demands.

With a nominal 26AH capacity (at the 20-hour rate to 10.5V), this model delivers up to 3.5 times the backup runtime of standard 7.5AH batteries under identical workloads. When heavy equipment powers on or experiences sudden current spikes, the battery delivers a massive 390 Amperes of maximum discharge current for 5 seconds. This high-rate discharge capability prevents low-voltage cutoffs by the UPS and handles initial inrush currents smoothly.

Thermal Resilience, Low Self-Discharge, and Fast Recharge

In Bangladesh, high ambient summer temperatures inside non-air-conditioned server spaces can strain power storage cells. The Voltan 12V-26AH battery is built to perform in challenging environmental conditions, featuring a wide operating temperature range:

• 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 composition suppresses self-discharge rates during idle standby periods. When stored at 25°C, the battery retains approximately 91% capacity after 3 months, 82% after 6 months, and 65% after 12 months. Supporting a maximum charging current of 7.8A, the battery accepts rapid energy recovery between frequent load-shedding cycles.

Multi-Industry Application Versatility

While deployed extensively in high-capacity UPS setups, the Voltan 12V-26AH battery serves as a versatile DC power source across various commercial and industrial fields:

• High-Capacity UPS Systems: Ideal for 2KVA, 3KVA, and 6KVA online and offline UPS units requiring high-reserve battery banks.

• Commercial CCTV & Access Control: Powers 32-channel DVR/NVR arrays, biometric locks, and security monitoring setups continuously.

• Telecommunications & Data Networks: Keeps core fiber network switches, server racks, and cellular base hardware active during extended outages.

• Medical Equipment & Solar Backup: Delivers stable DC backup for portable medical monitors, emergency lighting, and solar power storage.

Heavy-Duty ABS 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-grade T3/T8 copper terminals provide maximum electrical conductivity and low contact resistance, preventing terminal heating during continuous high-amperage output.

Physical Specifications:

• Length: 180mm (±2mm)

• Width: 168mm (±2mm)

• Height / Total Height: 130mm (±2mm)

• Approximate Weight: ~7.30 kg (16.1 lbs) ±4%

Real-Life Usage Scenarios in Bangladesh

1. Commercial Server Rooms & IT Workstations

Corporate offices running active local servers, network-attached storage (NAS), and multi-terminal workstations cannot afford sudden power drops that cause system file corruption. Installing a bank of Voltan 12V-26AH batteries provides the extended runtime needed to keep servers operational through short load-shedding cycles or perform controlled network shutdowns.

2. Non-Stop Commercial CCTV & Bank Security
