*****CE UL ISO certificated gel battery 12v 250ah *****
Key Features :
♦Gelled electrolyte made by mixing sulfuric acid with silica fume
♦The electrolyte is gel like ,immobile and does not leak ,enablinguniform 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
