VOLTAPURE 12V 40Ah VRLA AGM Rechargeable Battery

• Battery technology: Rechargeable valve-regulated lead-acid (VRLA), AGM type • Nominal voltage: 12V • Rated capacity: 40Ah at the 10-hour rate • Capacity at stated rates: 10HR: 40Ah; 3HR: 30Ah; 1HR: 22Ah • Terminal type: T14 threaded terminal • Internal resistance: Approx. 9 mOhm, fully charged at 25 degrees C • Dimensions (L x W x H / TH): 197 x 165 x 170 / 170 mm • Approx. weight: 12.50 kg, tolerance +/-3% • Maximum charging current: 12A • Maximum discharge current: 400A 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: 10 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

• 40Ah rated capacity at the 10-hour rate for extended standby duty. • Ten-year design float life at 20 degrees C under specified conditions. • T14 threaded terminal provides a secure connection for higher-current cabling. • Low 9 mOhm internal resistance supports efficient high-rate performance. • 400A five-second maximum discharge current for short peak loads within specification. • 12A maximum charging-current specification supports controlled charger selection. • AGM VRLA construction is sealed and requires no routine electrolyte top-up. • Wide discharge operating range from -15 degrees C to +50 degrees C.

• UPS cabinets and battery banks • Telecom and communications systems • Inverter backup systems configured for VRLA AGM batteries • Emergency and standby-power installations • Industrial control and infrastructure backup

• Ten-year design float life provides a longer design target than the five-year small-capacity models in the same range. • The T14 threaded terminal is more suitable for secure higher-current connections than small push-on terminals. • Low internal resistance and a published 400A peak limit support demanding short-duration loads. • Detailed OEM data supports charger configuration, temperature planning, and replacement decisions more effectively than generic label-only products. • VOLTAPURE combines documented specifications with local availability and support from Maamoon Est. in Egypt.
