• 26Ah capacity at the 20-hour rate for project and multi-battery systems. • AGM VRLA construction is sealed and requires no routine electrolyte top-up. • T4/T12 terminal configurations support compatible project connections. • Low 12 mOhm internal resistance supports effective high-rate output. • 360A five-second maximum discharge current for short peak demands within specification. • 7.8A maximum charging-current specification supports controlled charger selection. • Low self-discharge supports standby duty and planned storage. • Five-year design float life at 20 degrees C under specified conditions.

• Medium backup-power systems • Fire-alarm and security installations • Telecom cabinets • Industrial control systems • Series or parallel battery banks designed for compatible VRLA AGM batteries

• A compact block format delivers 26Ah capacity without moving directly to the larger 40Ah battery class. • The 360A peak limit and low internal resistance provide strong short-duration output for demanding backup loads. • T4/T12 terminal options support secure connections appropriate for project installations. • Published charge, temperature, self-discharge, and internal-resistance data improve engineering confidence over generic batteries with limited specifications. • VOLTAPURE provides documented OEM performance with local availability and support from Maamoon Est. in Egypt.
