     Product introduction    [兴发娱乐官方网]Small Valve-regulated sealing lead-acid storage battery is the product that uses the latest design of sealing structure and modern production technology, this kind of product has characteristics of small self-discharging, strong charging capability resistance, long battery storage, long life, no pollution and free maintenance,etc. Jitaly is devoted to study, produce, sale and service for 21 years, it has earlier passed ISO9001, ISO14001, OHSAS18001 system certification. [兴发娱乐官方网]Small Valve-regulated sealing 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, good performance of deep discharging.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 20839.2 [兴发娱乐官方网]Small Valve-regulated sealing lead-acid storage battery, product     classification Ø  GB/T 19639.1 [兴发娱乐官方网]Small Valve-regulated sealing lead-acid storage battery,  technology conditionØ  GB/T 19639.2 [兴发娱乐官方网]Small Valve-regulated sealing lead-acid storage battery, product     classification Ø  JISC 8704-1/2 : fixed lead-acid battery,                  part 2-1: valve regulation type:  test methods                 part 2-2: valve regulation type:  requirements  兴发娱乐xf938-Application fieldØ  small communication system, power system, emergency lighting system, automation control system, fire protection and safety alarm system, solar energy and wind energy system;Ø  computer supply power, portable instrument;Ø  medical equipment system;Ø  electric cars, electric tools;Ø  UPS, electronic energy system;Ø  emergency standby power supply, emergency flasher;Ø  railway signals, aeronautical beaconsØ  security system;Ø  electronic instrument and equipment, phone system power supply;Ø  DC power supply, automatic control system.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.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:The curve of capacity and temperature:Discharging capacity value of different discharging rate of battery will slowly increase when temperature increases. The curve is
