VOLTAPURE 12V 18Ah VRLA AGM Rechargeable Battery

• Battery technology: Rechargeable valve-regulated lead-acid (VRLA), AGM type • Nominal voltage: 12V • Rated capacity: 18Ah at the 20-hour rate • Capacity at stated rates: 20HR: 18Ah; 10HR: 16.8Ah; 1HR: 11Ah • Terminal type: T3/T12 • Internal resistance: Approx. 15 mOhm, fully charged at 25 degrees C • Dimensions (L x W x H / TH): 181 x 77 x 167 / 167 mm • Approx. weight: 5.20 kg, tolerance +/-4% • Maximum charging current: 5.4A • Maximum discharge current: 270A for 5 seconds • Float charging voltage: 13.50-13.80V at 25 degrees C; compensation -18mV/degree C • Cyclic charging voltage: 14.50-15.00V at 25 degrees C; compensation -30mV/degree C • Nominal operating temperature: 25 degrees C +/-3 degrees C • Operating temperature range: Discharge: -15 to +50 degrees C; charge: -10 to +50 degrees C; storage: -20 to +50 degrees C • Capacity by temperature: 40 degrees C: 102%; 25 degrees C: 100%; 0 degrees C: 85%; -15 degrees C: 65% • Self-discharge at 25 degrees C: Remaining capacity: 91% after 3 months; 82% after 6 months; 65% after 12 months • Designed float life: 5 years at 20 degrees C under specified float conditions • Construction: Lead-dioxide positive plate, lead negative plate, ABS container and cover, AGM separator, sulfuric-acid electrolyte, rubber safety valve, copper terminal

• 18Ah capacity at the 20-hour rate for medium backup installations. • AGM VRLA design is sealed and requires no routine electrolyte top-up. • T3/T12 terminal configurations support compatible secure connections. • Approx. 15 mOhm internal resistance supports high-rate performance. • 270A five-second maximum discharge current for short peak demands within specification. • Defined float and cyclic charging limits support accurate charger matching. • Wide discharge operating range from -15 degrees C to +50 degrees C. • Five-year design float life at 20 degrees C under proper charging conditions.

• Medium UPS systems • Larger fire-alarm and security panels • Telecom and communications equipment • Emergency-power systems • Industrial control and standby applications

• Provides substantially more standby capacity than 7Ah, 9Ah, and 12Ah compact batteries for longer-runtime applications. • The 270A published peak rating and 15 mOhm internal resistance support strong short-duration current delivery. • Terminal options are better suited to higher-current project connections than relying only on small push-on tabs. • Comprehensive model data enables more professional charging, temperature, and runtime assessment than generic products with limited documentation. • VOLTAPURE combines OEM-specified performance with local supply and support from Maamoon Est. in Egypt.
