Qoltec 53079 Deep Cycle Gel Battery 12V 200Ah (62.5kg)

For installations that demand steady, reliable power over long discharge cycles, the Qoltec 53079 Deep Cycle Gel battery stands apart from conventional lead-acid units. Its VRLA gel construction and 200Ah capacity make it a robust choice for solar arrays, UPS backups, telecom sites, and alarm systems where maintenance access is limited and performance cannot be compromised.

Highlights

• Deep cycle VRLA gel technology for repeated deep discharges without rapid degradation
• Nominal 12V, 200Ah (C10) capacity — delivers consistent energy for extended runtimes
• Maintenance-free, sealed, and spill-proof ABS housing for safe indoor/outdoor use
• Long design life of 10–12 years at 25°C, with up to 1200 cycles at 50% depth of discharge
• Low self-discharge (<3% per month) keeps the battery ready during storage or standby
• High current capability: max discharge 2000A (5s) and max charge 60A for flexible system design
• Durable T11 (M8 bolt & nut) terminals ensure secure, low-resistance connections

In daily use

This battery excels in cyclic applications where it is regularly discharged and recharged. The gel electrolyte immobilizes the acid, preventing stratification and reducing internal corrosion, which translates to stable voltage and capacity over thousands of cycles. Whether paired with a solar charge controller or a UPS inverter, the 53079 accepts a wide charging voltage range (13.5–14.7V) and tolerates temperatures from -20°C to 50°C during discharge, making it suitable for harsh environments.
