| Western Electrical DFM and GFM 2V Long Life Storage Batteries : |
The DGM 2V and GFM 2V batteries are a series of valve regulated lead acid batteries that specially designed for long life energy storage application field, come with AGM and Gel technology, heavy duty grids, thicker plates,over 18 years floating life design.
DFM 2V series is the general purpose battery with 18 years design life in float service. With heavy duty grids, thicker plates, special additives and updated AGM valve regulated technology, the DFM 2V battery provides consistent performance and long service life. The new grid design effectively reduces the internal resistance, which provides higher specific energy density and excellent high rate discharge characteristics.
GFM 2V Series come with silicon Gel electrolyte on the basis of DFM 2V series.
• Capacity range:200Ah-3000Ah.
• Voltage class: 2V.
• Long design life: more than 18 years.
• Polarity sign: symmetrical and more clear.
• Low self-discharge rate:≤3% per month.
• High recombination efficiency:≥99%.
• Compact structure and high specific energy.
• Wide operation temperature:-20°C to 60°C.
• Grid: thicker grid and radiative grid structure;
• Positive plate : Pasted flat type, latest grid alloy;
• Separator: AGM separator with high adsorptive and low resistance;
• Battery container: High strength ABS;

• Safety Valve: sensitive operate pressure and reliable equipped with explosion-proof arrester and acid filter.
| Batteries Series Specifications: |
|
• Non-Spillable, fully sealed technology ensures no electrolyte leakage, guarantees the handing safety and efficient operation in any position.
• Long service life in float or cyclic service up to 18 years @ 25°C.
• Maintenance-free, no need to check the gravity of the electrolyte or add water during the float service life.
• Heavy Duty lead-calcium alloy grids ensure good performance and service life in both float and cyclic applications.
• Low self discharge rate due to the Lead-Calcium alloy grids, allowed long time storage without recharge.
