Chapter 1 Safety Instruction 1.1 Abstract This chapter introduces about the safety signs and the precautions. Please carefully read it before operation to ensure safety. Safety Signs The safety signs indicate the safety issues that should be conformed to in installation, operation and maintenance. - Page 5 Do use special tools, instead of common tools during electrical connections. In addition, keep the tools in good insulation condition (e.g. wrap insulating tape around the bare metal parts) before using them to avoid short circuit and personal injury caused by tool contact with any live objects. Using the batteries of the same model Use batteries of the same model in the same set.

2.1 Model Introduction GFM series valve-regulated lead-acid battery(following called GFM battery for short) belong to SHUANGDENG structure rated voltage per cell is 2V. Take GFM-500 for example, its mean as fig.2.1-1 showing. -
Page 7: Storage
2.4 Storage Batteries can be stored in the environment of 0-35°C before installation. The storage time is usually 3-6months. Batteries should be charged if the storage time exceeds 6 months. Batteries should be kept in the dry, clean and ventilated environment. They cannot be kept in the environment of radiation, organic solvent and corrosive gas. -

The battery servicing surroundings should be dry, clean and airy, without large quantity of irradiation, infrared ray radiation, organic solvents and corrosive gas, and avoided the direct sun shining. - Page 10 In order to avoid increasing the circuitry voltage decrease, the battery modules should be near the load, and the cables, copper terminals and connecting wires selected should be suitable. When the batteries are used by the way of parallel-connection, the circuitry voltage decrease should be same to some extent to the best of one's best ability, and the fuses should also be equipped in every battery module.

Page 11: Check After Installation
10. The circuit switch should be disconnected, and the correctness mentioned in item has been confirmed (it should be empathized that the positive terminals of the battery should be connected with the positive counterpart of the charger, and negative to negative) before the battery system is connected with the charger or load. -
Page 13: Chapter 3 Operation And Maintenance
Chapter 3 Operation and Maintenance Abstract Operation and maintenance containing battery maintenance and precaution charge method relationship of temperature and capacity relationship of temperature and cycle life capacity checking switch power parameters setting usage requirement under power-off condition maintenance periods and requirement. This chapter introduces bout the operation and maintenance of GFM battery. -
Page 14: Temperature Effects The Battery Capacity
temperature increases by 1°C, then the float charging voltage should decrease by 3mV/cell; and if the temperature decreases by 1°C, then the float charging voltage should increase by 3mV/cell. 3.1.2.2 Balancing Charging Balancing charging voltage is usually set as 2.35V/cell (the mean value calculated from all of the battery voltages at 25°C), and the maximum charging current is set as 0.2C A, according to setting table to set Balancing charging time. -
Page 15: Temperature Impact On The Battery Life
In the formula: t is the discharging ambient temperature, K is temperature coefficient. In the 10hr capacity experiment, K=0.006/°C and 10hr capacity experiment, K=0.008/°C, 1hr capacity experiment, K=0.01/°C. Float charge characteristic: Float charge voltage should choose the manufactory recommendatory voltage value. And the float charge voltage value should make correspond adjustment according to the ambient temperature. -
Page 16: Capacity Determination
temperature of the batteries is around 35°C, then the expected floating charging service life is only 7.5 years. 3.1.5 Capacity Determination Balancing charging should be done before capacity determination. After balancing charging changes into float charging, float charging current will be between 1~2 mA/Ah, and if the float charging current is stable for about 2~3 hours, it shows that the battery system has been fully charged. - Page 17 which is the rated capacity of the battery. If the batteries are parallel connected, then , the rated capacity is the sum of the rated capacity of all of the individual battery paralleled (Batteries which have different rated capacities cannot parallel-connected).

Page 18: The Application Requirements For Power Supply Interruption Time
3.1.7 The Application Requirements for Power Supply Interruption Time Under the situation that the battery system has not been recharged after accident discharge, and just at the very time, the power supply of the communication station stops, often the battery system cannot be used to supply the power further. If continue working, it could lead the battery life shorter because of the battery deep discharge If the accumulative discharge capacity reaches 50%~80% of the battery rated... - Page 19 Individual battery terminal voltage should be determined every 3 months to judge their evenness, good record should be done at the same time. The maintenance person should periodically check that whether or not connection bars are loose or move, vent valve is loose, single battery is damaged and leaks, vent valve normally vents gas, battery is dry etc.

Page 22: Application Range
1 Application Range This operation guidance is used for battery charging for the first time after installing or battery recharging after long time storage. 2 Battery Recharging Requirement VRLA (Valve Regulated Lead Acid battery) is widely used in telecommunication. The battery is full charged While shipped as its self-character, automatic Self-discharge will occur because of chemical reaction when delivery, this cause battery capacity decreasing, OCV (open circuit voltage) dropping In a certain period, the voltage and capacity have to... -
Page 23: Battery Recharging Method
Therefore, long time storage batteries need recharge in order to recuperate the discharged capacity. The requirement of interval is below for recharging battery under different temperature. Storage temperature Longest interval over 30 once 4 months under 30 once 6 months The recharging interval is shorter, battery capacity is more renewed, the recharging time is shorter, and there is less effects on battery life. -
Page 24: Cycle Procedure
Turn on the breaker or fuse, and then turn on the charger to recharging batteries. Stop charging when reach the cut-off condition. At the last one hour before finish, test the battery voltage one by one, the battery which voltage is below 2.16V/cell should be delt with the method in chapter 3.3, if that battery still can not accord with the requirement, it should be rejected. -
Page 25: Charging Equipment And Tools
Remark: means 10 hour rate capacity, generally it is the same with rated capacity, for example, for 2V300Ah battery, its rated capacity C 300, for 12V100Ah battery, its capacity C 100; Usually there is only 1 cell in 2V monobloc and 6 cells in 12V monobloc; The total charging voltage must be less than the maximum voltage of the charger, if there are many batteries, please charge time after time;... - Page 26 recharging all the time. Battery terminals should be bright and clean. Check and clean terminals before connecting in order to decrease contact resistance. A circuit breaker must be stringed in the circuit to prevent battery damaged because of wrong connection. Make sure all the screws tightened reliably, otherwise there will be spark and heat while closing the circuit, this may cause battery burnt.
