Maintenance: Water regeneration ability, high reaction efficiency sealed, so no water or added acid battery maintenance in the whole process; 3, safe and reliable:? No acid spill, reliable safety valve automatically closes the device explosion-proof equipment Burke batteries make the entire process of using a more secure and reliable; 4, long life design:? Computer refined design corrosion of lead-calcium lead alloy grid, using corrosion-resistant ABS material and high sealed reaction efficiency to ensure the battery long life; 5, high performance:? 1) weight, high energy, internal resistance, high output power; high 2) charge-discharge performance, self-discharge control of each month at 2% or less (20 ℃); 3??? ) recovery performance, deep discharge or when the charger fails, short circuit for 30 days, it can still be used to restore the capacity equalization charging method;? 4) due to resistance of individual cells, capacity, consistency float voltage Therefore the use of batteries in the floating state without a balanced charge. ? 6, the temperature adaptability: safe, safely used at -30 ℃ ~ 50 ℃; 7, safe and easy to use and transport:? Man charged the factory, no free electrolyte, the battery can be placed horizontally, and can not hazardous materials, water, land transport; 8, affordable:? batteries high performance, long life, low maintenance costs to ensure that users get the most affordable products. ?? In practice, the battery will be a serious deterioration in three years, using little more than five years of battery. The reason is that the battery is in use there is no effective and reasonably manage and maintain, resulting in deterioration of the battery appeared in the early days, and there is no time found behind the battery, resulting in deterioration of the accumulation, aggravated battery resulting in premature retirement. ??? 2) on the battery operation, performance status is unknown??? Batteries if there is behind the battery, through a certain depth of discharge, the charge cycle, to a certain extent, reduce backward difference. However, the absence of good management tools, for the internal battery performance parameters, such as the internal resistance of the battery, the current surplus capacity, can not understand quite clearly, so appropriate measures can not be implemented. ??? 3) For single battery, the charging system reliability needs to improve??? As the current domestic charging mechanism of the DC system is not very perfect, the voltage drift exists in practice, the battery in the long-term floating punch state, If the float voltage deviation from the normal range of the red, it will cause the battery charge or charge less, long overcharge or charge less for very large affect battery performance. ?? Our advantage: Division I for a number of power supply manufacturers authorized partners, prices have obvious advantages, the perfect solution to the power supply design, specialty channels, professional installation, professional after-sales, UPS power supply in terms of our omnipotent. ? In addition, I Division with offices throughout the country, the regular customers of UPS power systems for routine maintenance, as far as possible to maximize the life of UPS systems achieve optimal operational state. ? We are committed: the machine fails within three years, we will be the first time to send the nearest maintenance personnel rushed to the scene, from a failure to complete the repair does not exceed 24 hours, no charge!
