German DETA Silver Cedar Battery 2EG200 2V200Ah Silver Cedar Battery, Wind Farm

Features of Yinshan battery products:

1. The interior is gel electrolyte, without free electrolyte. Under strong charging conditions, there will be no leakage of electrolyte.

2. The electrolyte has a residual capacity of about 20%, so it is still extremely reliable during high-temperature operation or overcharging, and the battery will not produce "drying" phenomenon. The high and low temperature range of batteries is wide.

3. Adopting a high-sensitivity low-pressure one-way air valve can ensure timely discharge of overpressure gas. The battery will not experience leakage or swelling. The battery is sealed and does not require special ventilation equipment.

The 4.2V single cell has reached the standard rated capacity (2500Ah), so the battery uniformity is very good, allowing for the mixed use of new and old batteries with different capacities and production years in series and parallel. There will be no "circulation" phenomenon between battery packs.

5. The concentration of colloidal electrolyte is consistent above and below, and there will be no acid stratification phenomenon. Therefore, the reaction is uniform, and under high rate discharge conditions, the electrode plate will not deform and cause internal short circuits.

6. Therefore, it can create a high columnar battery with a small footprint (such as a 3000Ah/48V battery pack occupying only 2.9 square meters). The 200Ah-1500Ah units are available in vertical or horizontal placement options.

7. The concentration of electrolyte is low, at 1.24Kg/L, so the battery has a long service life, lasting 18-20 years at room temperature of 20 ℃.

8. And the battery capacity remains constant, gradually increasing to 110% of the nominal value during the initial use. So the actual usage capacity of the battery is relatively high.

9. Adopting a tubular positive electrode plate ensures that the active material will not peel off or detach from the core rod during use, making it particularly suitable for deep discharge cycles or loads that require long-term depletion (such as solar energy storage systems).

10. The other electrode is made of high-quality antimony free alloy with extremely low self discharge rate. At room temperature of 20 ℃, the daily self discharge rate of the battery is less than 0.05%, and it still maintains 50% of its original capacity after two years of storage.

According to the standard of IEC 896-2:1995D Volume 5.3, test the C5 discharge rate, 60% discharge depth, and after 1200 cycles of discharge, the battery still maintains its original nominal capacity of not less than 80%.
