2V400AH is Telecom battery. The capacity is defined at discharging current 40A more than 10 hours to OCV not less than 1.8V, 27.0 KGS. The Maintenance free structure make the batteries convenient to operate. The 2V batteries are mainly applied to Telecommunications, Solar System, Wind Power System, Data Center, Big UPS.
With heavy duty grids, thicker plates, special additives and updated AGM valve regulated technology, the 2V series battery provides consistent performance and long service life. The strong grid design effectively reduces the internal resistance, which provides higher specific energy density and excellent high rate discharge characteristics. The expected service life can be 20 years.
2V400AH storage battery characteristics:
Maintenance free; low self-discharge, Long lasting,
lead-acid is mature and inexpensive.
Performance stays high and stable
Safe operation, less dry-out than general AGM, no electrolyte stratification
Strong configuration against shake and vibration.
High rate discharge more than 10C for 5 seconds workable, no BMS requested
Good capacity retention during storage
IEC60896 standard
U.N. 3.3 238 certificated
California Proposition 65 certified
2V400AH Telecom battery is heavy duty stationary battery. Each battery is a single cell with high capacity. The paste and grid of 2V series is extra strong materials. The chemical formulation is different from 12V batteries. The maintenance battery does not produce acid moisture, no damage to other equipment. Special additives to paste and electrolyte are also improve the performance. 2V400AH Long life GEL battery is competitive in cycle life and cost. 2V400AH solar battery is the most safest battery for Telecommunication Power Stations: No fire, no explosion and high recycle value.
Installation and Maintenance
1. Always connect the positive terminal firstly.
DO NOT reverse polarity otherwise the electrical equipment of motorcycle will damage.
2. During assembling the battery packs, isolation gloves is recommended .
3. DO NOT over discharging the battery, charging the battery timely after discharging.
4. Dismount or disconnect the negative terminal of battery。
5. Never to short-circuit the terminals.
6. Regularly check the terminal connection and the surface of terminal is clean or not to ensure well connection.
7. Storage the battery where is 5~25℃, dry, ventilated and no direct sunshine. Keep the battery at least 2m away from the heat source. Regularly check and maintain the battery.
