***** solar gel batteries 12v 50ah for solar energy *****
Key Features :
♦Gelled electrolyte made by mixing sulfuric acid with silica fume
♦The electrolyte is gel like ,immobile and does not leak ,enabling uniform reaction of each part of the plate .
♦High rate discharge performance due to tight assembly technology
♦Strong heat dissipation and wide operating temperature range
♦Avoid acid mist being separated out , environment friendliness
♦Efficient venting system release excessive gas automatically
Applications :
♦Solar and wind energy storage system
♦EPS and UPS battery backup
♦Signal system , emergency lighting system , security system
♦Telecommunication Equipment
♦Power plant and transmission system
