No mist invincible battery when the battery agents, on the surrounding environment and supporting the design of non-corrosive, can be installed directly to the battery in the office or equipment room, without the need for preservatives. Charge-discharge characteristics of the battery self-discharge effect. To the user from the manufacturing plant, about to be delayed a few months time. Lead-acid batteries, for example, at ambient temperature 30 ℃ storage eight months, half of the remaining battery capacity is only at the factory, so for the purchase of new batteries and UPS support, generally charging a longer period of time This is called the initial charge. Initial charge current to charge the battery should be 0.1C, the battery after the discharge end can be recharged, called the normal charge. UPS is currently commonly used two charging methods: float and pulse charge. The so-called floating charge refers to the output of the rectifier and battery in parallel, and at the same time to load, in fact, at this time the current rectifiers provide two routes, all the way to the load, and the other way to the battery, the battery in order to supplement their internal loss, floating rechargeyour simple wiring work, to improve the UPS output transient response is good. Pulse charging characteristics of the battery capacity with a charging current is changed, in this way the charging, the charging time can be shortened. Invincible batteries leak fluid, maintenance-free world's first green look unique, environmentally friendly products. Special additives to make batteries with superior high-current discharge performance. Statistical techniques and the production of a large number of applications, the battery consistency. Unique multi-layered extreme labyrinth seal structure, no leak acid. High density lead paste, hot and humid curing process, long-life design. Invincible Battery Features: 1, maintenance-free battery: a unique gas recombination technology (GAS RECOMBINATION) technology. Do not need regular maintenance rehydration. Reduce worries 2, high security and reliability of user: the automatic open and close the safety net (VRLA), to prevent outside air being sucked battery performance while protecting the internal battery, while preventing the gas generated due to charging and other abnormalities caused by internal pressure the battery is destroyed. Fully enclosed battery float under normal circumstances there will be no discharge of electrolyte and acid mist, harmless to human body. 3, long life: at 20 ° C environment, FM series battery float life of up to 3-5 years, FML series battery float life of up to 5-8 years, GFM series battery float life of up to 10-15 years. 4, easy to install: a new top and lateral connections, user-friendly in a variety of ways to connect the battery, greatly reducing installation effort and risk 5, self-discharge rate: high quality multi-lead calcium alloy, reduces battery self-discharge rate, at an ambient temperature of 20 ° C, Kstar battery within six months without having to add power to use. Improve battery efficiency 6, ability to adapt to the environment: in the -20 ° C - + 50 ° C ambient temperature are use for desert plateau climate. Special power can be used for riot District 7, placing strong randomness: Special diaphragm (AGM) firmly adsorbed electrolyte so that does not flow. Whether the battery stand up or lying down will not divulge, to ensure the normal use. 8, green pollution: acid batteries do not require anti-corrosion measures room, with the same set of electronic equipment in a room. 9, the new FML series batteries have a longer service life using special multi-tin alloy cathode, stronger than conventional lead-calcium alloy corrosion resistance, superior cycle life. Alexandra optimized radial grid design, with a more powerful output power. Unique lead paste formulations and manufacturing processes, fully conducive to the formation 4BS, and make sure the battery has a long life of 5-8 years float. Rational use of additives. So PCL (capacity early losses) to be a better solution. Silver-plated copper terminals and special design, more convenient connections to ensure excellent electrical performance ☆ 12V series (commonly used models) Model Voltage (V) Capacity (Ah) (20 hour rate) Reference size (mm) Weight (kg) The total height of the length and breadth WD4-12 12 4 90 * 70 * 101 * 107 1.48 WD4-12 12 4 90 * 70 * 101 * 107 1.48 WD7-12 12 7 151 * 65 * 94 * 100 2.20 WD12-12 12 12 151 * 98 * 95 * 101 3.56 WD17-12 12 17 181 * 77 * 167 * 167 5.32 WD24-12 12 24 165 * 125 * 175 * 182 8.10 WD38-12 12 38 197 * 165 * 175 * 180 13.0 WD65-12 12 65 350 * 166 * 178 * 178 21.0 WD100-12 12 100 407 * 173 * 210 * 240 30.0 WD120-12 12 120 407 * 173 * 210 * 240 32.0 WD150-12 12 150 483 * 170 * 241 * 241 40.0 WD200- 12 12 200 520 * 240 * 218 * 224 60.0 WD230-12 12 230 520 * 240 * 218 * 224 63.0 WD250-12 12 250 520 * 268 * 220 * 250 73.0
