sealed construction the unique construction and sealing techniques of dahua batteries guarantee leakproof operation in and position with no adverse effect to capacity or service life.
electrolyte suspension system dahua batteries utilize an electrolyte suspension system consisting of a high porosity, totally absorb and contain the electrolyte. no silica gels or any other contaminants are used.
gas generation dahua batteries incorporate a built-in design that controls gas generation and induces recombination of more than 99% of gases generated during float usage.
maintenance free operation there is no need to check specific gravity of the electrolyte or add water to dahua batteries during float service life .in fact, there is no provision for this type of maintenance.
low pressure valve regulated system all dahua batteries are equipped with safety release valves, designed to operate between 0.98-196.1kpa and automatically reseal. hence, there is never an excessive accumulation of gas within the battery.
heavy duty grids heavy duty lead calcium tin alloy grids provide an extra margin of performance and service life in either float or cyclic applications, even after repeated over discharges.
cyclic service life more than 1000 discharge / recharge cycles can be realized from dahua batteries, dependent on the average depth of discharge.
float service life dahua dhb series batteries have an expected life span of 3 to 5years in float service applications.
self discharge-shelf life the self discharge rate of the dhb series at room temperature is approximately 3% of rated capacity per month.
operating temperature dahua dhb batteries may be operated over a broad range of ambient temperatures.
deep discharge recovery dahua batteries recover their capacities even after repeated deep discharges.
