FIAMM Batteries in India – Reliable VRLA Power Backup for Factories & Telecom

FIAMM batteries maintain strong demand in India for industrial UPS systems, telecom backup and standby power where consistent performance under tough conditions is non-negotiable. Plant engineers, facility managers and purchase teams select FIAMM for proven reliability in factories, data centers, hospitals and critical infrastructure across major industrial regions.

Why FIAMM batteries perform in Indian conditions

FIAMM sealed lead-acid (VRLA) batteries—AGM and gel designs—handle deep discharge tolerance and long float service better than many alternatives. They manage voltage fluctuations, ambient temperatures up to 40°C (with derating), high humidity and dusty factory floors common across India.

Key advantages include:

• • Temperature resilience – Reduced capacity loss at 30–40°C compared to standard VRLA; maintains 80% rated capacity even in un-cooled Indian factory rooms.

  • Low self-discharge – Under 3% per month, ideal for infrequent grid outages; batteries stay ready even after 6 months standby.

  • Vibration resistance – Suitable for manufacturing floors, rail sites and generator rooms; reinforced grids handle constant machine vibration without shedding.

  • Wide voltage compatibility – Works seamlessly with Indian UPS brands (48V, 96V, 110V, 220V DC systems); standard DIN/F10 terminals fit 95% of installations.

  • Predictable end-of-life – Clear capacity fade curve lets maintenance plan replacements 6–12 months ahead, avoiding emergency failures during peak season.

  • Hot-swappable design – Individual 12V blocks can be replaced without shutting down the string; zero downtime for data centers and hospitals.

  • Flame-retardant casing – UL94-V0 rated enclosures reduce fire risk in crowded electrical rooms.

  • Multi-year warranty support – 3-year pro-rata standard, backed by PAN-India service network for fast claims processing.

For pure standby UPS duty with minimal daily cycling, FIAMM VRLA remains more cost-effective than lithium while delivering reliable 3–7 year service life.

Primary applications across Indian sectors

FIAMM batteries serve these high-demand segments:

Technical Specifications Indian Buyers Need

Capacity Range
7Ah to 300Ah+ per 12V block. Parallel strings scale to 1000+Ah total for large UPS systems. Compact 7–38Ah blocks fit data center racks; 150–300Ah blocks suit telecom towers and 20kVA+ UPS.

Design Life
5–12 years at 20°C float service; 3–7 years at 30–35°C (typical Indian ambient). High-temp models maintain 80% capacity after 1000 cycles at 35°C.

Proper sizing for Indian UPS systems

Follow these steps for accurate FIAMM battery sizing:

1. Load calculation: Total kW × backup hours × 1.2 (inverter losses) = required kWh

2. String Ah: Total Ah ÷ parallel strings (respect max block rating)

3. Temperature correction: Derate 20–30% capacity for 35°C+ rooms

4. Voltage matching: Confirm charger float (13.5–13.8V/12V) and boost (14.1–14.4V) settings

5. End-cell voltage: Size for 1.75–1.80V/cell at required runtime

Most Indian online/offline UPS brands accept standard FIAMM blocks without modifications.

Maintenance schedule for maximum life

FIAMM VRLA requires light but regular attention:

Clean/dry installation away from heat sources extends life 20–30%.
