Reduce worries 2, high security and reliability of users:? Automatic open and close the safety net (VRLA), to prevent outside air being sucked to protect the internal battery battery performance, while preventing other gases generated by charging caused by internal pressure exception is the destruction of the battery. Fully enclosed battery float under normal circumstances there is no electrolyte and acid mist discharge harmful to humans. ? 3, long life: at 20 ° C environment, FM series battery float life of up to 3 to 5 years FML series battery float life of up to 8--10 years. 4, easy to install:?? The new top and lateral connectivity, user-friendly in various ways to connect the battery, greatly reducing the risk of installation 5, self-discharge rate:? Using high-quality lead-calcium Multiple gold, reduces battery self-discharge rate, temperature 20 ° C at the Kstar battery within six months do not need to add power can be used. Improve battery efficiency 6, ability to adapt to the environment:? Can all use at -20 ° C ~ + 50 ° C ambient temperature, suitable for desert plateau climate. Special power that can be used riot zone 7, placed strong randomness: Special diaphragm (AGM ?????) strongly adsorbed electrolyte so that does not flow. Battery Whether stand up or lying down will not divulge to ensure the normal use. 8, Green *** ?;? Battery housing need not have acid corrosion measures with the same set of electronic equipment in a room. 9, the new L series battery has a longer life? Multiple special alloy anode using tin, stronger than conventional lead-calcium alloy corrosion resistance, superior cycle life. ? Optimization Shan radial grid design, with a more powerful output power. ? Unique lead paste formula and manufacturing process, fully conducive to the formation of the BS, ensure that the battery has a longer use 8 to 10 years float life. Rational use of additives. So PCL (capacity early losses) to be a better solution. ? Tongxin slow silver terminals and special design, more convenient connections, ensure excellent electrical performance. SORENSEN battery application advantages 1, reliable product quality: SORENSEN to the derivation of TQM total quality management, follow healthy PDCA cycle model, from suppliers to service products are equipped with quality control chain system, to all aspects of quality systematic analysis of the situation, so as to achieve the purpose of continuous improvement to ensure the quality of products Kstar battery brands remain at the forefront of industry standards. 2, the leading manufacturing scale:? SORENSEN Huizhou battery production base covering 10,000 square meters, has a production after eight production lines, production capacity of 800,000 KAH / years. Regardless of any user location on the mainland, are safe and timely delivery. 3, Perfect battery management technology online SORENSEN has leading R & D and manufacturing scale level and supporting UPS batteries and colleagues focused on the internal resistance of the battery management and monitoring technology research and development, to provide comprehensive, professional in the field of UPS batteries, reliable battery monitoring and management solutions to ensure that users get high reliability. ? 4, a unique patented battery leak fluid? Seal leakage phenomenon of lead-acid batteries are likely to occur for all valve hole, Kstar Release patented leak-proof tray also technology that reduces transportation and installation of the battery direct collision, the maximum to avoid the bottom of the battery rupture, and to accommodate unexpected battery rupture is the leakage, which can effectively prevent fire caused by short circuit of the battery pack, significantly enhanced user safety. ? 5, close to the user's nationwide service network SORENSEN first in the industry to establish a "National Customer Service Center Technical Support Center Regional Service Center - Authorized service center" to cover a wide range of infrastructure, rational layout, close to the user of a multi-stage service system to provide customers nationwide may close. Prevents loose connections and is not strong if contact is not strong, to a lesser extent, poor conductivity occurs to line contact portion fever, line loss is large, the output voltage is low, the impact of electrical power, so that with mileage reduction or not normal riding ; if contact is not strong at the terminals unit (mostly the fault is in the terminal and connection joints), the terminal will be a lot of heat, combined with the impact of terminal and sealant over time will leak occurred "crawl acid" phenomenon. If there is not strong during travel or contact with the charging process, may produce circuit, will have a strong spark circuit, may point inside can (especially just a charged battery, the battery can explode due to higher gas and enough battery power, disconnect the spark when relatively strong, the possibility is quite large.) to bear more intense vibrations of electric vehicles in operation, therefore, to deal with all reliability assessment connected with the connector should be "self-locking" feature, prevent vibration and is pulled off, to connect with the battery lugs should take connectors and solder to weld, connectors and wiring application crimping (crimping can also be increased again after the solder bonding reliability ). 5, to prevent exposure to the sun in the sun exposure will increase the battery temperature, battery activity of each active substance increases, affecting battery life. Fourth, the lead-acid battery short circuit causes of lead-acid batteries and lead-acid battery internal short-circuit means is connected to the positive and negative groups. Lead-acid battery short circuit is mainly manifested in the following aspects: (1) open circuit voltage is low, the closed circuit voltage (discharge) quickly reach the termination voltage. (2) high-current discharge, the terminal voltage rapidly drops to zero. (3) open, the electrolyte density is very low, at low temperatures the electrolyte will be icing. (4) charging, the voltage rises very slowly, always remains low (sometimes zero). (5) During charging, the electrolyte temperature rises very rapidly. (6) charged electrolyte density rises very slowly or hardly changed. (7) does not take charge or take gas bubbles appear late. The main cause of internal short circuit lead-acid battery has the following aspects: good (1) Spacers quality or defect, so that through the electrode active material, resulting in positive and negative plates virtual contact or direct contact. (2) spacer channeling bits resulting in positive and negative plates are connected. (3) off the plates active material expansion, due to excessive deposition of the active material shedding, resulting in positive and lower negative electrode plate edge or side edges and sediment caused by contact with each other is connected to the positive and negative plates. Cause inner (4) conductive objects fall into the battery positive and negative plates are connected. The formation of (5) welding electrode group "lead flow" is not divisible, the "lead beans" between positive and negative plates in the presence or assembly, the charge-discharge process caused damage to the separator is connected to the positive and negative plates.
