GEL 65Ah Solar Battery: Autonomy for your small projects

Gel batteries are sealed batteries: no maintenance, no need to add distilled water. Greater safety than open lead batteries.
A gel battery can withstand 50% discharge and recover its rated capacity if the discharge 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: 65Ah
  • Dimensions: 348 x 167 x 178 mm
  • Weight: 19.2 Kg
