Product introduction:   Communication and electricity lead-acid storage battery is the latest generation of products which used advanced technology. The products have good characteristics of high specific energy, low self-discharge, long cycle life, good consistency of floating charge, and convenient installation. Jitaly is devoted to study, produce, sale and service for 21 years, it has earlier passed ISO9001, ISO14001, OHSAS18001 system certification. Communication and electricity lead-acid storage battery has passed TLC, UL,CE, we will provide you safe and reliable products.Product technical features:Ø  Plate: use strong corrosion-resisting alloy, imported additive and Eirich vacuum mixing technology, advanced curing process.Ø  Partition: use the high performance AGM partition which is developed by our company and domestic manufacturer.Ø  Shell: use the modified ABS to ensure the intensity of battery shell, and low water penetration rate, so as to avoid some battery problems such as craze, ballooning and thermal runaway.Ø  Terminal post: use the special terminal post structure, and imported high performance sealant.Ø  Safety valve: use the high sensitivity acid flame-proof structure. Execution standard (new standard)Ø  GB/T 19638.1  fixed valve regulation lead-acid battery                   part one: technology conditionsØ  YD/T 799   valve regulation sealing lead-acid battery for communicationØ  JISC 8704-1/2  fixed lead-acid battery,                   part 2-1: valve regulation type: test methods                   part 2-2: valve regulation type: requirementsØ  IEC 60896-21/22  fixed lead-acid battery                   part 21: valve regulation type: test methods                   part 22: valve regulation type: requirements 兴发娱乐xf938-Application fieldØ  telecommunication, Mobile, Unicom, railways, shipping, and all kinds of standby power for communication, signal systems.

Ø  standby power for electric system and nuclear power station.Discharge performance:Under the condition of the environment temperature 25, the characteristic curve about various discharging rate of unit cell is:Charge performance:Usually use constant voltage limited current charge after battery discharging, the charging voltage is 2.35V/unit(25), charging current is0.15C10A. The curve about charging current and charging time is:Self-discharge performance:a. Use multi-element alloy for battery, and special electrolyte additive, store 1 month at normal temperature, self-discharging 3.b. Self-discharging is associated with storage temperature. When the temperature is low, the self-discharging is low, and when the temperature is high, the self-discharging is high. After a period of storage, unit cell can obtain the surplus capacity approximately though the open-circuit voltage. The relationship between voltage and surplus capacity is:impulse discharging performance:The curve of capacity and temperature is:Discharging capacity value of different discharging rate of battery will slowly increase when temperature increases. The curve isGFMJseries    main parameter list various types of battery and terminal types:terminal number and size
