CSB HRL 1234WF2 12V 9.0Ah VRLA AGM-batterij

Where standard lead-acid batteries falter under deep cycling, the CSB HRL 1234WF2 excels with a 6–9 year design life and robust AGM construction. This 12V 9.0Ah valve-regulated battery delivers dependable standby power for UPS systems, emergency lighting, security panels, and medical devices, without the maintenance headaches of flooded cells.

Highlights

• 12 V nominal voltage, 9.0 Ah capacity (20HR to 1.75 V/cell)
• AGM technology with valve-regulated design – no watering, no spills
• Low self-discharge: less than 3% per month at 25 °C
• Wide operating temperature range: -15 °C to 50 °C (discharge)
• F2 Faston tab terminals (250 series) for secure, quick connections
• UL Recognized Component; manufactured under ISO 9001, ISO 14001, OHSAS 18001

In daily use

Engineered for float service, the HRL 1234WF2 accepts a float charging voltage of 13.5–13.8 V at 25 °C, while cycle charging requires 14.4–15.0 V. Its internal resistance of approximately 19 mΩ ensures stable voltage output under load, and the maximum discharge current of 100 A (5 seconds) handles momentary surges. The battery’s ABS container (UL94-HB) resists impact and vibration, and the compact footprint fits standard 12 V 9 Ah battery compartments. Whether deployed in a UPS, alarm panel, or portable equipment, it delivers consistent power with minimal maintenance.
