Description Luminous 240Ah 12V Gel Battery GPTTEX 240 The Luminous GPTTEX 240 is a powerful 240Ah 12V tall tubular gel battery designed for solar and backup use. With over 1,500 charge cycles at 50% DoD, it offers long-lasting performance, zero maintenance, and safe, spill-proof operation—perfect for homes, offices, and off-grid systems that need reliable energy every day. Key Features Gel Technology: No water top-up required; spill-proof and maintenance-free. Gelled Electrolyte: Prevents stratification and plate shedding, supports partial state-of-charge (PSOC) operation, and offers a longer life span. Deep Cycle Design: Offers stable backup duration with high energy efficiency. High-Grade Imported Separator: Ensures low electrical resistance and high charging efficiency. Built-in Pressure Release Valve: Explosion-proof and self-regulating for internal pressure. Eco-Friendly: No fume emissions, making it safer for indoor and residential use.
