Battery Application

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 :

♦EPS and UPS battery backup
♦Solar and wind energy storage system
♦Telecommunication Equipment
♦Power plant and transmission system
♦Signal system , emergency lighting system , security system
