FIAMM FLB400 12FLB400 High-Rate UPS Battery

Description

3. Key Technical Specifications

4. Product Introduction & Supply Chain Strategy

The FIAMM FLB400 is a high-rate, valve-regulated lead-acid (VRLA) battery designed for critical uninterruptible power supply (UPS) infrastructure, emergency lighting systems, and industrial DCS control rack backups. Industrial facilities rely on its high energy density and absorbed glass mat (AGM) construction to deliver instantaneous standby power, preserving control telemetry and preventing ungraceful shutdowns during main grid dropouts.

Sourcing this unit as New Surplus delivers immediate availability without the long factory lead times associated with specialized battery manufacturing runs. Utilizing new, uncommissioned stock guarantees fresh plate chemistry, zero cycle degradation, and full grid structural integrity. This approach avoids the massive risks of second-hand or poorly stored batteries, which frequently suffer from internal sulfation, dry-out, and unexpected cell failure during load drops.

5. Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Isolate the target UPS or DC distribution bus using Lock-Out/Tag-Out (LOTO) isolation breakers.
2. Put on insulated safety gear, including rated rubber gloves, safety goggles, and acid-resistant protection.
3. Inspect the new FLB400 casing for shipping damage, cracking, or terminal deformation. Measure open-circuit voltage to verify it exceeds 12.6 V DC.

Stage 2: Removal

1. Disconnect the inter-battery links starting from the main negative terminal, moving sequentially to the positive pole to prevent short circuits.
2. Unbolt support brackets or rack retainers holding the old battery.
3. Remove the depleted battery using proper mechanical lifting equipment due to the 34.5 kg unit mass.

Stage 3: Installation (Clone & Seat)

1. Clean rack mounting trays and position the new FLB400 with terminals oriented identically to the original layout.
2. Install insulated copper interconnectors between battery blocks.
3. Torque all M8 female terminal bolts to the manufacturer-specified setting (typically 8 to 10 N·m) using a calibrated insulated torque wrench.

Stage 4: Power-On & Testing

1. Verify correct string polarity at the main bus disconnect before closing the circuit breaker.
2. Apply float charging voltage (2.26 V/cell at 25 °C, or ~13.56 V DC total per module).
3. Perform a brief discharge test under load to confirm zero abnormal voltage drop across the string connections.

6. Firmware/Software Versions & Upgrade Notes

• System Parameter Configuration: Ensure your UPS or DC charger system controller is configured for AGM VRLA battery profiles.
• Charging Voltage Settings: Set float voltage to 2.26 V/cell at 25 °C (13.56 V for a 12 V unit). Set boost/equalization charging to 2.40 V/cell if supported.
• Temperature Compensation: Enable thermal voltage compensation on the charger set to -2.5 mV/cell/°C from a base of 25 °C to prevent thermal runaway in high-ambient environments.
• Firmware Notes: Update the host UPS battery management system (BMS) configuration parameters with the new Ah rating (100 Ah) and total cell count to maintain accurate run-time calculations and automated diagnostic alarm thresholds.

7. Frequently Asked Questions (FAQ)

Q: Is this FLB400 battery brand new or pulled from an active system?

This battery is 100% New Surplus inventory. It has never seen field service, has not been cycled in an operational plant, and remains preserved in fresh factory condition.

Q: Why choose New Surplus over low-cost refurbished or reclaimed batteries?

Reclaimed or used VRLA batteries suffer from grid plate corrosion and internal capacity degradation that cosmetic restoration cannot fix. Purchasing verified New Surplus ensures full design lifespan (10–12 years Eurobat rating) and prevents sudden, catastrophic power losses during real-world outage events.

Q: How long can this battery be stored before installation?

Due to its low self-discharge rate (<2% per month at 25 °C), the FLB400 can be stored for up to 6 months without requiring a refresh charge. If stored longer, apply a refreshing charge at 2.40 V/cell for 24 hours before service entry.

Q: Does this battery require electrolyte maintenance or water top-ups?

No. The FLB400 utilizes VRLA AGM technology with a 99% internal gas recombination efficiency. It is completely sealed, non-spillable, and maintenance-free throughout its operational lifespan.

Q: What warranty coverage applies to this module?

We back our New Surplus batteries with a full 1-year replacement warranty. If a unit exhibits manufacturing defects or fails performance parameters under correct operating conditions, we replace it directly from our stock.
