Sealed Lead-Acid Battery AVACOM WP2,9-12TR 12V 2.9Ah with F1 (4.8 mm) Terminal

The AVACOM WP2,9-12TR is a sealed lead-acid battery providing a nominal voltage of 12 V and a capacity of 2.9 Ah in a compact, valve-regulated, maintenance-free design. It is equipped with an F1 (4.8 mm) faston terminal for straightforward, secure connections and is intended for applications that require reliable short-term power, such as backup modules, alarm panels, small uninterrupted power supplies (UPS) and portable devices. The sealed construction prevents electrolyte leakage and reduces the need for periodic maintenance.

Advantages

The battery delivers a stable 12 V output and moderate capacity suitable for many small-scale power applications. The valve-regulated sealed lead-acid chemistry ensures maintenance-free operation and safe installation in various orientations without spillage. The F1 (4.8 mm) faston terminal enables fast, tool-assisted connection and simple replacement in devices that use standard quick-connect terminals. The compact form factor and reliable discharge characteristics make it suitable for confined spaces and predictable backup durations.

Suitable for

• Alarm and security systems
• Small uninterruptible power supplies (UPS) for routers, modems and network devices
• Portable medical or measuring equipment with low to moderate power draw
• Emergency lighting and exit signs
• Backup power for electronic control units and sensors

When it may not be suitable

This battery is designed for low- to moderate-drain applications and short-term backup. It may not be appropriate for high-drain devices or applications that require long runtime at high currents. Also, for installations that need frequent deep discharges or continuous cycling, a battery chemistry designed for deep-cycle use (such as certain AGM or lithium-based solutions) may offer better lifecycle performance.

Key specifications

• Nominal voltage: 12 V
• Rated capacity: 2.9 Ah (at specified discharge rate)
• Battery type: sealed lead-acid, valve-regulated (maintenance-free)
• Terminal type: F1 (4.8 mm) faston
• Construction: leak-proof, installable in various orientations
• Typical applications: backup power, alarm systems, small UPS, portable equipment

How to use

Install the AVACOM WP2,9-12TR in the device following the manufacturer’s instructions for polarity and terminal connection. Use the F1 faston terminal to connect the corresponding quick-disconnect leads; ensure connections are secure and free of corrosion. Charge the battery using a charger or charging circuit appropriate for sealed lead-acid batteries, observing recommended float and cyclic charge voltages. Avoid overcharging and deep discharges to prolong service life. Store unused batteries in a cool, dry place and charge them periodically according to storage recommendations.

What to consider before purchase

• Ensure device compatibility with a 12 V, 2.9 Ah sealed lead-acid battery and F1 (4.8 mm) terminals.
• Confirm required runtime and expected discharge current to verify capacity is sufficient.
• Check available space and mounting options to accommodate the battery's physical dimensions.
• Verify the charging method and voltage profile used by your device are suitable for sealed lead-acid batteries.

Usage recommendations

For reliable backup performance, keep the battery charged when in standby use and replace it when capacity noticeably degrades. Use a charger designed for sealed lead-acid batteries and avoid exposing the battery to high temperatures or freezing conditions to maintain optimal life and safety.
