JOZOKING 12V7Ah UPS Sealed Maintenance Free Battery
As the key energy storage element in an uninterruptible power supply system, JOZOKING batteries enable a seamless power transition in just 10 milliseconds in the event of a grid failure. Our batteries actively filter out grid disturbances such as voltage fluctuations, surges, frequency shifts, etc. and deliver stable AC power through proprietary innovations and precision manufacturing processes made in Germany.
● 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
