Maintenance Free solar battery 12V7AH used for solar power system
Unique prescription of corrosion-resisting grid alloy and active material, advanced production technology, distinctive design, special gas recombination and compact construction, all of these together with strict technical and quality control make nice people battery possess the following features:
1. Long service life: Under the normal condition , the designed service life under float service is up to 10year for DP, and DG series.
2. Low self-discharge: At the ambient temperature 25°C, the rate of self-discharge less than 1.8% after 28days storage.
3. Sufficient capacity: Guarantee 100% capacity, moreover , the voltage and capacity of battery is accordant. No disproportion phenomenon of voltage in valve regulated battery of whole series caused by negative absorption.
4. Wide operating temperature range: nice people battery can charge by 0 ~ 40°C , discharge by -20 ~ +55°C . Due to unique prescription of alloy and lead-paste, nice people battery has good discharge capability under low temperature, also strong capability to protect from corrosion.
5 .Good sealing capability: No pollution and corrosion, which ensures nice people battery operate safely and efficiently in side and vertical position The sealed construction can combine the generated gas to water, and no need to add water or check their specific gravity during the life of nice people batteries.
6 .Good electric conductivity: Adopting red copper with silver plated patent terminal can make batteries discharge with high current.
7 .Good charge acceptance performance: So the charge acceptance of nice people battery is more efficient, the charge time for nice people battery is shorter, the capacity easier and quicker to be recovered.
8. Safe and reliable venting system: Safe venting system can eliminate the danger of explosion under large pressure.
