Our company for the long battery manufacturers agents, specializing in various types of light, large, medium and small dense battery series. Long battery
Charge discharge characteristics
The battery has self discharge effect. It takes about a few months to delay from manufacturing workshops to users. Taking lead-acid battery as an example, the storage capacity of the battery is only half of the factory when the storage temperature is 30 months at the environmental temperature of 8 months. Therefore, for the newly purchased and UPS batteries, the battery should be charged for a long time, which is called the initial charging. The initial charging current of the battery should be charged according to 0.1C, and the battery can be recharged after discharge. This is called normal charging. At present UPS is widely used in two kinds of charging mode: pulse charge and floating charge. The floating charge refers to the output of the rectifier and battery in parallel, and at the same time to supply the load current in this rectifier provides two ways, one way to load another road to the battery, to supplement the battery internal loss, float charge mode wiring is simple, to improve UPS output transient response characteristic is good. Pulse charging is characterized by charging current changing with the battery capacity, charging in this way can shorten the charging time.
1. charging voltage
Because the UPS battery belongs to the standby mode, the city power is in the state of charge in normal condition, and only when the power is cut off will the discharge be discharged. To prolong the service life of the battery, the charger UPS generally uses constant voltage current limiting control mode, the battery is full after that is converted to a floating state.
For output voltage of 12V battery, normal float voltage between 13.5~13.8V. Float voltage is too low, the battery charging dissatisfaction, float voltage is too high, will cause overvoltage charging. When the float voltage exceeds 14V, that is over voltage charging. It is forbidden to charge the battery overvoltage, because the overcharge charge will cause the electrolyte contained in the battery to be electrolyzed into hydrogen and oxygen, so that the electrolyte concentration increases, resulting in shortened battery life, and even damage.
2. charging current
The charging current of the battery is generally expressed as C, and the actual value of C is related to the capacity of the battery. For example, if the battery is 100Ah: C is 100A. The best charging current of Panasonic lead acid free maintenance battery is about 0.1C, and the charging current must not exceed 0.3C. Charging current too large or too small will affect the service life of the battery.
The ideal charging current should adopt the phased constant current charging mode, that is, the larger current should be used in the early stage of charging, and then the charging current should be changed into smaller current after charging for a certain time, and the smaller current will be used at the end of charging. The charging current is generally designed to be 0.1C. When the charging current exceeds 0.3C, the charging current can be considered as over current charging. Avoid using fast charger charging, otherwise it will make the battery in "instantaneous over current charging" and "instantaneous over-voltage charging" state, resulting in the use of batteries for power consumption decline, and even damage the battery. Over current charge will lead to the battery plate bending, active substances fall off, resulting in the storage battery power supply capacity decline, serious damage to the battery.
(1) long service life
High strength tight assembly process can improve the compactness of battery assembly, prevent the live material from falling off, and improve the service life of battery.
Low acid specific gravity electric liquid, improve the battery charge acceptance ability, enhance the deep discharge cycle capacity of the battery.
The increase was not due to design, make sure the battery electrolyte depletion shorten battery life.
So the normal float design life of up to GFM series battery for more than 15 years (25 C)
(2) high rate discharge performance is excellent
High strength tight assembly process, the battery internal resistance is very small, high current discharge characteristics excellent, more than the average battery increased by more than 20[%].
(3) low self discharge
High purity raw materials and special manufacturing process, self discharge is very small, storage at room temperature for more than half a year, also need no power supply.
(4) simple maintenance
The design of the special oxygen absorption cycle overcomes the phenomenon that the battery loses water during the charging process, and the water content of the electrolyte has almost no change during the use, so the battery does not need water supply in the use process, and the maintenance is simple.
(5) high safety
Special safety is installed inside the battery.
(6) simple installation
The battery has the advantages of vertical, lateral and stacked installation, with small footprint and flexible and convenient installation.
(7) clean and environmental protection
The battery does not produce acid mist, no corrosion on the surrounding environment and supporting design, can be directly to the battery installed in the office or facilities in the room, without preservative treatment.
Simple maintenance: CGB series battery is the real maintenance free battery, in normal service life, without water or dilute acid, electrolyte dry up will not occur.
High safety: CGB series of batteries in the correct use process, the battery inside or outside the face of open flame, does not occur * *, spontaneous combustion and rupture, high safety.
Reliability is good: CGB series battery in the factory before 100% through the load test (check the tightness, internal resistance, open circuit voltage, closed circuit voltage), to ensure that all the ex factory battery no leakage, poor performance and so on.
Consistency is good: CGB series batteries pass through charging and discharging cycle before the factory 100%, and strictly screening and matching according to customer requirements, to ensure good consistency between the batteries, especially suitable for UPS selection.
Long life: CGB series battery production process using lead calcium multi element alloy special design unique, the product has a very long life in float use and recycle.
High rate discharge performance is good: CGB series batteries are designed with special design, which greatly improves the high rate discharge performance of the products, and can be used for large current deep discharge.
High energy battery: CGB series is a special formula can greatly improve the battery weight ratio of energy can reach 40WH/KG-45WH/KG.
Suitable temperature range: CGB series battery temperature has wide application range, can be used between -15 C and 45 C normal.
Low self discharge rate: CGB series battery using high quality raw materials components and strict production process, so that the product has a strong ability to maintain charge.

The CB series is the VRLA battery, the design life of 5-10 years (20 C). Suitable for UPS, EPS and other emergency standby power supply equipment and uninterruptible power supply.prepare
Matters needing attention：
1) the use of UPS environment should pay attention to good ventilation, good heat dissipation, and keep the environment clean.
2) without inductive load, such as currency-counting machine, fluorescent lamp, air conditioning, so as to avoid damage.
3) the UPS output load control in about 60% is the best, highest reliability.
4) the UPS load is too light (such as 1000VA UPS with 100VA load) depth of discharge will damage the battery, will reduce battery life, should be avoided.
5) appropriate discharge, contribute to the activation of the battery, such as long-term stop electricity, every three months should be UPS with artificial broken electricity load discharge time, so you can extend the service life of the battery.
6) for the majority of small UPS work, open UPS, boot to avoid load startup, the work should be closed for UPS; the network room UPS, because most of the network is 24 hours of work, so UPS must also be all-weather operation.
7) UPS after discharge should be promptly charged, avoid the battery due to excessive self discharge and damage.
