Sealed Lead‑Acid Battery csb HRL 1225 12V 5.8Ah — rechargeable VRLA battery for backup power

csb HRL 1225 is a sealed lead‑acid (VRLA) rechargeable battery with a nominal voltage of 12V and a rated capacity of 5.8Ah. It is designed for standby and backup power applications where a maintenance‑free, compact energy source is required. The battery’s valve‑regulated construction and absorbent glass mat (AGM) components ensure low self‑discharge, leak‑free operation and predictable discharge behavior suitable for UPS systems, security equipment and small telecom devices.

Advantages

The HRL 1225 provides stable discharge characteristics and a long shelf life in intermittent use, while its sealed design eliminates the need for electrolyte top‑up. Its compact rectangular housing and standardized terminal layout simplify installation in battery trays and enclosures. The battery is suitable for upright or side mounting in many configurations and delivers reliable standby power under typical load conditions encountered in uninterruptible power supplies and alarm systems.

Suitable for

• Uninterruptible power supplies (UPS) for home and small office
• Alarm and security systems, control panels
• Small telecom and network devices requiring standby backup
• Emergency lighting and exit signs
• Portable diagnostic and monitoring equipment

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 5.8 Ah (at specified discharge rate)
• Battery type: Sealed lead‑acid, valve‑regulated (VRLA), AGM design
• Recommended operating temperature range: typical manufacturer range for standby use
• Mounting orientation: upright or side position compatible
• Performance: Designed for standby/float service with stable recharge acceptance

How to use

Install the battery into the device or battery compartment following the equipment manufacturer’s instructions and respecting polarity. Use a compatible charger or float/standby charging system configured for sealed lead‑acid batteries at the recommended float voltage. Avoid deep discharges whenever possible; after use, recharge promptly to restore capacity. Observe proper ventilation and secure connections when placing the battery into UPS cabinets or enclosures.

Recommendations

For reliable long‑term performance, maintain the battery on a suitable float charger when in standby service, inspect connections periodically for corrosion, and replace the battery at the end of its expected service life or if capacity falls below required thresholds for the application.
