Sealed Lead Acid Battery AVACOM PBLO-12V012-F2A 12V 12Ah for UPS and backup systems

AVACOM PBLO-12V012-F2A is a sealed lead acid (SLA) 12V 12Ah battery designed for use in UPS units and backup power installations. The battery is maintenance-free and spill-proof, providing a stable 12V standby supply suitable for emergency lighting, security systems, small telecommunication devices and other applications that require a reliable SLA battery of this voltage and capacity.

Advantages

The battery is valve-regulated and leak-proof, requiring no regular electrolyte maintenance and minimizing installation constraints. Its 12Ah capacity offers extended standby runtime compared with lower-capacity SLA cells, while the compact, rectangular construction enables straightforward mounting in cabinets, racks or small enclosures. The chemistry and construction provide consistent voltage output under standby and cyclic conditions typical for UPS and emergency systems.

Suitable for

• Uninterruptible power supplies (UPS) for home and small business
• Emergency and exit lighting systems
• Alarm and security systems
• Telecommunication and small network equipment backup
• Portable power modules and testing rigs

How to use

Install the battery following the UPS or device manufacturer’s instructions, ensuring correct polarity and secure terminal connections. Use the appropriate charger or UPS charging circuit designed for sealed lead acid batteries and avoid overcharging. Place the battery in a well-ventilated environment, keep it upright, and avoid exposure to open flames or temperatures outside the device specification. For replacement, match nominal voltage and capacity to the existing battery bank and verify connector compatibility.

Recommendations

For optimal service life, store and operate the battery at moderate temperatures and keep it charged between uses. Periodically test batteries in standby service and replace units that show significant capacity loss. Use chargers and UPS systems with SLA-compatible charge profiles to prevent reduced lifetime from improper charging.
