GEL Ultracell 12V 150Ah battery: Long-lasting, maintenance-free solar autonomy
Gel batteries are sealed batteries: no maintenance, no need to add distilled water. Greater safety than open lead 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: 150Ah
- Dimensions: 485 x 170 x 240 mm
- Weight: 43.5 Kg
