This Ultracell UCG275-12 gel battery is suitable for energy storage for a 12 V solar battery. It provides 275 Ah, or a nominal energy of approximately 3.30 kWh, and can be integrated into photovoltaic installations requiring high capacity at low voltage. Its gel technology contributes to maintenance-free use.

  • Specifications: It operates at 12 V with a capacity of 275 Ah (3.30 kWh) and measures 522 x 268 x 220 mm, weighing 73 kg.
  • Cells: It uses gel (lead) technology designed for energy storage, with a claimed life of up to 1,200 cycles at 50% discharge.
  • BMS + communication: It does not require a BMS and does not offer CAN/RS485 communication, as it is a 12 V gel battery.
  • Compatibility + scalability: It is intended for use in 12 V solar batteries and can withstand a maximum discharge current of 2500 A for 5 seconds, with a nominal service life of 15 years at 20 °C.

GEL Ultracell 12V 275Ah battery: High-capacity solar energy storage

Gel Batteries 275Ah

Gel batteries are sealed batteries: no maintenance, no need to add distilled water. Greater safety than open lead-acid batteries.
A Gel battery can withstand 100% discharge and recover its rated capacity if the discharged holding time is short. This series has a longer discharge time than other batteries. Its special plate design increases battery life, particularly in warmer temperatures. A separator within the battery enhances its performance. It also has a longer shelf life.

  • Nominal voltage: 12V
  • Capacity: 275Ah
  • Dimensions: 522 x 268 x 220 mm
  • Weight: 73 Kg
