CSB HR1221WF2 VRLA Battery 12V 5Ah 21W F2 Terminal

The EATON CSB HR1234W F2 is a high-performance VRLA (Valve Regulated Lead Acid) battery designed for reliable backup power in stationary applications. Utilizing advanced AGM (Absorbed Glass Mat) technology, this lead-acid battery ensures consistent energy delivery for critical systems. Its sealed, maintenance-free construction makes it an ideal choice for environments where reliability and long service life are essential.

Advantages

The primary benefit of this VRLA/AGM design is its high discharge power, which is crucial for handling the initial power surges required by connected electronics. The battery is completely maintenance-free, eliminating the need for electrolyte checks or water refilling. Its robust construction offers high resistance to shocks and vibrations, while the leakproof design allows for installation in various positions. Furthermore, the battery exhibits minimal internal resistance, ensuring high reliability when multiple units are connected in series within a single UPS system.

Suitable for

• UPS backup power supplies
• Electronic fire alarm systems (EPS)
• Electronic security systems (EZS)
• Telecommunications equipment
• Servers, NAS, routers, and workstations

This battery may not be suitable for applications requiring deep cycle usage, such as electric vehicles or frequent daily discharge-recharge cycles, as it is specifically engineered for standby power environments. It is also not intended for use in high-temperature environments that exceed the manufacturer's recommended operating range, as this can significantly reduce its service life.

Key specifications

• Rated voltage: 12 V
• Capacity: 9 Ah (at 20-hour discharge)
• Technology: VRLA / AGM (Absorbed Glass Mat)
• Terminal type: Faston 6.3 mm (F2)
• Maximum discharge current: 130 A (within 5 seconds)
• Dimensions: 151 x 100 x 65 mm
• Weight: 2.5 kg

To use the battery, ensure it is installed in a clean, dry, and well-ventilated location. Connect the F2 terminals securely to your device, ensuring correct polarity. If the battery has been in storage, it is recommended to fully charge it before initial use to ensure optimal performance. The battery is designed for stationary use and should be kept in a stable environment to maintain its service life.

What to consider before purchase

• Verify the physical dimensions to ensure it fits your device compartment.
• Check that the F2 (6.3 mm) terminal type matches your existing equipment.
• Confirm the voltage and capacity requirements of your UPS or security system.
• Ensure the battery is stored in a cool, dry place if not used immediately.

For optimal longevity, avoid deep discharging the battery and ensure it is kept in a temperature-controlled environment. If you are uncertain about compatibility with your specific UPS model, consult the manufacturer's documentation or use a professional configurator tool to verify the correct replacement part.
