The UPS power battery is often used in our lives, so how to charge the discharge, this article will introduce you. First, regarding the UPS power supply battery charging 1. When the UPS floats charge, use the charging voltage 2.

275V / single-single, and calculate current charging or 0.002ca or less. When the temperature is 0c or more or more, it is necessary to correct the charging voltage, with 20C as a starting point per change, single voltage change-3mv.

2. When the temperature is charged or more than 35 ¡ã C or more, the temperature is started at 20 ¡ã C, each change, one recharge voltage adjustment -4mv / single. 3, charging initial current control below 0.

25CA. 4, the amount of charge is set to 100-120% of the amount of discharge, but the ambient temperature is below 5c, set to 120-130%. 5, the lower the temperature (5c or less) The longer the charging end time, the higher the temperature (35C or more), the easier overcharge, so, especially during cycling, charging is performed in 5c ~ 30c.

6. To prevent overcharge, install the charging timer, or automatically convert to a trickle charging method. 7.

When charging, the battery temperature should be controlled within the range of -15c ~ + 40c. 2. Control the battery temperature in the range of -15 ¡ã C - + 50 ¡ã C regarding the UPS power supply battery discharge.

Continuous discharge current is controlled below 3CA (h controlled below 6CA). The discharge termination voltage varies depending on the size of the current, substantially as follows. Pay attention to the press, the voltage is not lower than the following voltage.

Remove quickly after discharge. If you accidentally charge it, please charge it immediately. Third, when installing the battery When installing the battery, please be sure to follow: 1, do not install the battery near the sealed space or fire, otherwise there is a danger that caused explosion and fire.

2, do not use the ethylene film, there is a possibility of static electricity, and sometimes explosions sometimes caused by static electricity. 3, do not install the battery in places where possible into the water, otherwise there is an electric shock, the danger of fire. 4, please do not install the battery in more than -40 ¡ã C ~ 60 ¡ã C.

5, do not use the battery in a dusty place, otherwise it is possible to cause battery short circuit. 6. When putting the battery in the box, pay attention to air circulation.

7, do not have sticky or label objects to press the upper cover, due to the exhaust valve below the upper cover, the gas generated in the battery will not escape. 8, when the number-floating charge, the plug-in terminal battery can only be associated with three columns, and the bolt fastening terminal is not particularly limited, but the inclusion of the parallel number of small reliability. In addition, when connected to the line, it is necessary to consider that the wiring conductor and contact resistance between the columns are equivalent, in order to keep each column charge and discharge battery balance, please do not exceed three columns in actual use.

9. At the same time, the use capacity is different, the new is different, when the battery is different, due to the difference in characteristics, it is possible to damage the battery and machine, so avoid use. Fourth, regarding UPS Power Battery Storage 1, please pay attention to the temperature exceeding the range of -20 ¡ã C ~ + 40 ¡ã C.

2, the battery must be kept in a fully charged state when the battery is kept. If you lose a part of the capacity due to self-discharge during transport or during storage, please add electricity. 3, long-term storage, to make up for the self-discharge during the storage, please make supplement.

When kept in more than 40C, there is a bad impact on the battery life, please avoid! 4, please keep the low temperature and well ventilated place. 5. If the battery pack is inadvertently wet during the storage or transfer process, the wet carton should be removed immediately to avoid the wet carton that is wet, causing a conductor to cause battery discharge or burn the positive terminal.

5. About UPS Power Battery Daily Inspection and Maintenance 1, regularly check the battery, if it finds that dust is contaminated with dust, please clean with water or warm water. Do not use organic solvents such as gasoline, banana water or oil, and avoid using chemical fiber cloth.

2, when the floating charge, the indicator value of the total voltage or indicator disk during battery charging is deviated from the base value (¡À 0.05V / mononegery) as shown in the following table (¡À 0.05V .
