NPP HR1224W F2-12V 6Ah Rechargeable AGM Battery 144Watts 24Watt Cell Sealed Lead Acid UPS Batteries Replacement for NS1250

The NPP HR1224W 12V 6Ah High Rate Sealed Lead Acid Battery is engineered for performance-critical backup systems requiring stable, high-power output in compact form. With a rated capacity of 24 Watts per cell (144 Watts total at 15min-rate), this model provides approximately 40% higher discharge capability than standard 12V 6Ah batteries — ideal for UPS, alarm, and emergency lighting applications. Engineered Power & Efficiency: Constructed with advanced lead-calcium grids and low-resistance AGM separators (≈19mΩ internal resistance), the HR1224W supports 90A maximum discharge current (5 sec) while maintaining voltage stability under high load. The optimized grid structure ensures efficient energy transfer and reduced heat generation during rapid discharge cycles. Compact Size & Direct Replacement: Measuring 5.94"(L) × 2.01"(W) × 3.90"(H) and weighing only 1.94 kg (4.28 lbs), this unit fits seamlessly into most 12V 6Ah–6.5Ah battery trays. It is a direct replacement for models such as APC Back-UPS NS1250, CP800AVR, BE750G2, and Eaton 500/650VA UPS units, as well as many gate opener, alarm, and emergency light systems. Reliable Backup Across Applications: The HR1224W is ideal for: UPS Systems: APC Back-UPS NS1250, CP850PFCLCD (≤800VA) Alarm & Security Systems: Honeywell Vista 20P, DSC PC1832, GE Concord 4 Emergency Lights: Dual-Lite EVHC12V, Lithonia ELB-0606 Garage & Gate Openers: LiftMaster 485LM, Chamberlain 940EV Network & Control Power: UPS2000-A, router backup modules Safety & Long Life:

Highlights: 【Engineered for High-Rate Discharge】 Delivers 24W per cell constant power (15min-rate at 25°C) and 90A peak current (5 sec) with only 19mΩ internal resistance. Up to 30% higher output power than standard 6Ah batteries ensures reliable small UPS units (≤800VA) requiring instant output and stable voltage during transitions. 【Precise Fit & High Power Density】 NPP HR1224 features compact size 5.94"×2.01"×3.90" and quick plug-and-play installation with F2 terminals, replacing most 12V 6Ah 6.5Ah batteries such APC Back-UPS NS1250, CP800AVR, and BE750G2. 【Premium AGM & Safety Construction】 Non-spillable VRLA design with FR ABS casing and AGM separators, Maintenance-free and safe for indoor installation. Wide Operating range (-15°C to 50°C) and stable float voltage (13.6–13.8V) ensures long-term 24/7 standby reliability for security and monitoring installations. 【Multi-Application Compatibility】Compatible with Honeywell Vista 20P, DSC PC1832, and GE Concord 4 systems. Perfect for LiftMaster 485LM, Chamberlain 940EV, and Dual-Lite EVHC12V emergency lighting units. Provides safe, high-rate output during short-duration discharge, supporting critical backup applications. 【NPP Brand Quality & Certification】 NPP is a top battery manufacturer with a total of 6 mega-factories around the world. UL, CE, IEC, ISO14001, ISO19001, OHSAS18000, TLC certified. Each battery tested for voltage stability and capacity retention (≥91% after 3 months). Designed for 3–5 years float life, ensuring consistent performance for backup systems.
