Valve Regulated Lead Acid (VRLA) and Sealed Maintenance Free (SMF) AGM batteries are leak-proof, maintenance-free energy storage cells. TNS Engineering is the official distributor of genuine Kenson deep-cycle batteries in Bangladesh (7.5Ah to 200Ah) with high-density lead-calcium grids.
VRLA & SMF Deep Cycle Batteries in Bangladesh — Selection & Backup Guide
High-performance energy storage is the cornerstone of reliable industrial backup. Kenson VRLA-SMF Batteries, distributed nationwide in Bangladesh by TNS Engineering Ltd., incorporate Absorbed Glass Mat (AGM) separator technology, 99.994% pure virgin lead plates, and heavy-duty flame-retardant ABS containers.
Unlike conventional open-vent flooded automotive batteries, Kenson SMF batteries emit zero acidic fumes, require no distilled water refilling, and feature a low self-discharge rate (< 3% per month), making them the industry standard for Online UPS, pure sine wave IPS, emergency medical systems, and substation control panels.

Frequently Asked Questions about BATTERY in Bangladesh
Q:What is the float charge voltage for Kenson 12V SMF batteries?
The recommended float charging voltage is 13.5V to 13.8V per 12V battery at 25°C. For cycle service, charge between 14.4V and 14.8V with maximum charging current limited to 0.3C.
Q:How does ambient temperature affect VRLA battery life in Bangladesh?
VRLA battery design life is rated at 25°C. For every 8°C–10°C continuous rise in operating room temperature, battery lifespan is reduced by approximately 50%. Proper ventilation or air conditioning is recommended.
Q:How can I distinguish genuine Kenson batteries from counterfeit units in Bangladesh?
Genuine Kenson batteries imported by TNS Engineering feature embossed brand markings, holographic serial verification, tamper-evident seals, and official TNS warranty registration documentation.
Q:What is the official warranty on Kenson SMF batteries?
Kenson SMF batteries imported by TNS Engineering carry an official replacement warranty of 3 to 12 months depending on the Ah rating, backed by our central engineering testing lab in Dhaka.
