Datasheet of sealed battery
Product Processing of sealed battery
Communication and signal systems such as telecommunication, China mobile, and railway etc.
Electric power system and nuclear power plant, energy storage of solar and wind power generation;
UPS, medical equipment, and emergency illumination etc.
Light Supply System
Plates:1% higher than the average content of tin plate, effectively prevent corrosion and sulfide of the plate.
Electrolyte:Silicon-containing salt composition, effectively prevent the battery from dehydration.
Paper separator:using domestic top brands, a variety of materials certification.
Terminals:All copper materials, there are many other battery suppliers using lead terminals.
Battery products:enough plate number, enough battery capacity, enough weight.
1.Don’t near the hot source and don’t under the sunshine.
2.Don’t charge in the sealed container.
3.No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.
4.Don’t store in the space of acid gas. You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.
