• 12Ah capacity at the 20-hour rate for medium standby loads. • AGM VRLA construction is sealed and requires no routine electrolyte top-up. • T2/T1 terminal options for compatible equipment connections. • Approx. 19 mOhm internal resistance supports efficient current delivery. • 180A five-second maximum discharge current for short peak loads within specification. • Specified float and cyclic voltage ranges support correct charger selection. • Low self-discharge supports standby duty and controlled storage. • Five-year design float life at 20 degrees C under proper conditions.

• Medium-capacity UPS systems • Security and fire-alarm systems • Emergency-lighting installations • Access-control and monitoring systems • Extended standby-power equipment

• Offers a useful middle-capacity step between compact 9Ah batteries and larger 18Ah blocks. • The published 180A short-duration limit supports more accurate high-rate compatibility checks. • AGM VRLA construction reduces maintenance compared with flooded lead-acid batteries by eliminating routine water top-up. • Detailed OEM data for charging, temperature, internal resistance, and self-discharge supports better system design than generic label-only products. • VOLTAPURE provides documented specifications with local availability and support from Maamoon Est. in Egypt.
