CSB HR1234W 12V 9Ah AGM UPS Battery – High-Rate Sealed Lead-Acid

The CSB HR1234W is a 12 V 9 Ah sealed lead-acid battery in valve-regulated flat-plate AGM construction — the high-rate backup cell behind countless UPS units, alarm panels and emergency-lighting systems. The 'HR' (high-rate) design is built to deliver strong current for the short, heavy discharges a UPS demands.

It meets IEC 61056-1/2 and carries a EUROBAT 3–5 year design life for standby use, with Faston 6.3 mm terminals and ~204 W (15 min) output. Maintenance-free and sealed, it mounts in any orientation.
