GBS12/33-BB Battery12V33AH

**GEL Technology Battery - SOLHR & PV**

**Model: GBS 12133**

---

**Features:**
- GBS delivers extended cycle life and prolongs battery life even in elevated ambient temperatures. The heat generated can easily dissipate to the case walls as the entire cell volume is filled with gel.
- Immobilization of the electrolyte in the gel prevents acid stratification.
- Maintenance-free operation (no water topping-up required).
- Low self-discharge rate, with less than 2% capacity loss per month.
- Uniform distribution of the special valve opening and closing pressure is crucial for the battery's long cycle life.

**Applications:**
- Solar power stations
- Telecommunications installations
- Traffic lights
- Street lighting
- Wind power
