Battery kit AVACOM RBC166 12V 2×9Ah — rechargeable sealed lead-acid batteries, replacement set

AVACOM RBC166 12V 2×9Ah battery kit contains two rechargeable sealed lead-acid batteries designed as a direct replacement or spare power source for compatible UPS units and emergency power systems. Each battery delivers 12 volts and 9 ampere-hours of capacity, offering short-term backup power to maintain connected equipment during brief outages and to support controlled shutdown procedures. The batteries are supplied as a matched pair to ensure consistent voltage and run-time performance in systems that require two 12V modules in series or parallel configurations as specified by the device manufacturer.

Advantages

The kit uses sealed lead-acid chemistry that does not require the user to add electrolyte and permits installation in a variety of orientations. Pre-matched capacities and terminal types simplify replacement and reduce the risk of imbalance between modules. These maintenance-free batteries provide stable 12V output suitable for UPS, alarm systems, and other DC-powered devices, and are designed for reliable standby performance under normal ambient conditions.

Suitable for

• Replacement batteries for compatible UPS units that accept 12V 9Ah modules
• Emergency power modules in small office or home telecom and network equipment
• Backup power for security and alarm systems requiring sealed 12V batteries
• Maintenance or spare set for scheduled battery replacements in critical systems

Key specifications

• Battery type: sealed lead-acid (rechargeable, maintenance-free)
• Nominal voltage: 12 V (each battery)
• Capacity: 9 Ah (each battery)
• Configuration: two-battery kit (matched pair)
• Intended use: standby and backup power for UPS, security, and telecom equipment

How to use

Before installation, ensure the host device is powered down according to the manufacturer’s instructions and that you observe proper safety procedures for handling batteries. Install the two batteries into the battery compartment or tray following the device’s connection diagram; confirm correct polarity and secure terminal connections. After installation, recharge the batteries using the UPS or appropriate charging system until fully charged. Dispose of replaced batteries in accordance with local regulations for lead-acid battery recycling.

Usage recommendations

Store and operate the batteries at moderate ambient temperatures, avoid prolonged exposure to high heat, and perform periodic charge checks if units remain in standby for extended periods. Use matched pairs as supplied in the kit to maintain balance in multi-battery configurations and follow the equipment manufacturer's guidance for charging rates and replacement intervals.
