Sealed Lead-Acid Battery AVACOM PBLO-6V004.5-F1A — 6V 4.5Ah VRLA rechargeable

AVACOM PBLO-6V004.5-F1A is a sealed lead‑acid (VRLA) rechargeable battery rated at 6 V and 4.5 Ah. Designed for compact backup power applications, it offers a maintenance‑free, spill‑proof construction and is suitable for both standby and cyclic operation. The battery is geared toward devices where a compact form factor and reliable low-voltage power are required, such as small UPS units, emergency lighting and alarm systems.

Advantages

The valve‑regulated lead‑acid design ensures the battery is maintenance‑free and can be mounted in multiple orientations without leakage. Its nominal 6 V output and 4.5 Ah capacity provide predictable runtime characteristics for small backup loads. The sealed construction reduces the need for ventilation and handling precautions compared with flooded cells, and the battery’s durability supports repeated charge/discharge cycles typical in standby and cyclic use.

Suitable for

• Small uninterruptible power supplies (UPS) for consumer or light commercial equipment
• Emergency and exit lighting systems
• Alarm and security systems
• Portable medical devices and monitoring equipment with compatible voltage
• Small electronic devices and instruments requiring rechargeable backup

Key specifications

• Nominal voltage: 6 V
• Nominal capacity: 4.5 Ah (at specified discharge rate)
• Battery type: Sealed lead‑acid, VRLA
• Design: Maintenance‑free, spill‑proof
• Intended use: Standby and cyclic operation

How to use

Install the battery in equipment designed for 6 V input, ensuring correct polarity and firm terminal connection. Use a compatible charger or charging circuit matched to sealed lead‑acid chemistry and follow manufacturer guidance for float and cyclic charge voltages. Avoid deep discharges where possible to extend service life; when storing the battery for extended periods, keep it at a partial state of charge and recharge periodically according to storage guidelines.

Usage recommendations

Operate the battery within recommended temperature ranges and use appropriate charge control to prevent overcharging. Replace the battery if capacity diminishes significantly or if the device indicates end‑of‑life; dispose of the battery according to local regulations for lead‑acid batteries.
