The Ultracell UCG100-12 GEL battery is a 12 V, 100 Ah battery designed for energy storage for backup and moderate cycling applications, particularly for stand-alone solar installations. Its VRLA (gel electrolyte) lead-gel technology is described as sealed, and the battery is used in floating mode or cyclic use according to the recommended voltages. It measures 328 × 173 × 232 mm and weighs 31 kg.

  • Specifications: 12 V, 100 Ah (C10), 328 × 173 × 232 mm, 31 kg, maximum charging current 30 A.
  • Cells: VRLA (Valve Regulated Lead Acid) lead-gel technology with gelled electrolyte.
  • BMS + communication: Not applicable, as this is a gel battery (no BMS or communication indicated).
  • Compatibility + scalability: Cyclic use (14.4–14.8 V) or maintenance/float (13.5–13.8 V) at 25 °C, with an indicative cycle life of approximately 1,200 cycles at 50% depth of discharge and a maximum discharge current of 1,000 A (5 s).

Battery GEL Ultracell 12V 100Ah - 1200 cycles | Self-sufficient solar system | Maintenance-free

VRLA 100Ah gelled electrolyte (GEL) battery, proven, robust technology for backup applications and moderate cycling. It is sealed and maintenance-free.

Main applications

This technology is particularly suited to specific applications where reliability and maintenance are key criteria:



  • Backup power and UPS: Ideal for use in "floating" mode (permanent load-holding).
  • Alarm and security systems.
  • Power for isolated sites with occasional use: Perfect for a weekend cottage, occasional lighting or small applications.
  • Marine or camper van applications: Its waterproof design and vibration resistance are assets for nomadic use with moderate requirements.

Points to consider for optimum use



  • Charger configuration: To achieve its maximum service life, this battery requires precise setting of charging voltages.
  • To avoid irreversible damage, the recommended values must be observed.
  • Charging and discharging currents: We advise you not to exceed the currents recommended by the manufacturer.
  • Excessively high currents can lead to premature wear and tear.
  • Technology comparison: For equivalent weight and size, lithium technology offers superior storage capacity. The energy efficiency of a GEL battery (charge/discharge) is around 85-90%.
