Qoltec Deep Cycle Gel Battery 12V 150Ah 44.5kg

Reliable energy storage is the backbone of any off-grid or backup power system, yet many batteries fail prematurely under deep cycling or high temperatures. The Qoltec Deep Cycle Gel Battery 12V 150Ah addresses this with a robust valve-regulated lead-acid design that delivers consistent power over hundreds of cycles. Its gel electrolyte immobilizes the acid, preventing leakage and allowing safe operation in any orientation, while the maintenance-free construction means you never need to top up water or check specific gravity.

Who is it for

This battery suits solar installations, UPS systems, telecommunications equipment, recreational vehicles, marine applications, and electric vehicles. It is ideal for users who need a dependable, long-lasting energy source that can handle deep discharges without significant capacity loss. Whether you are building an off-grid cabin, upgrading a boat’s house bank, or ensuring continuous power for critical telecom gear, this 150Ah unit provides ample storage and peace of mind.
