The UPS battery is often used in our lives, so how to charge the discharge, this article will introduce you.
First, about charging
1 When the temperature is 0c or more or more, it is necessary to correct the charging voltage, with 20C as a starting point, a single voltage change-3mv.
2, when recurring, the charging voltage is charged at 2.40-2.50V / single-density (set value at 20 ° C). When the temperature is charged below 5c or more, the temperature is carried out at 20 ° C as a starting point, each change, one calibration voltage to adjust -4 mV / single.
3. The current current is controlled below 0.25 cA.
4, the 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 in particular, it is better to charge in 5C to 30C.
6. To prevent overcharge, install the charging timer, or automatically convert to trickle charging.
7. The battery temperature should be controlled within the range of -15c to + 40c during charging.
Second, about discharge
When discharges, control the battery temperature in the range of -15 ° C – +50 ° C.
The continuous discharge current is controlled below 3CA (H controls below 6CA).
The discharge termination voltage varies depending on the size of the current, and is generally as described below. Note that the voltage is not lower than the following voltage.
Please charge quickly after discharge. Please charge it immediately after you accidentally over-discharge.
Third, installation considerations
When installing the battery, be sure to follow the following:
1. Do not install the battery in the vicinity of the sealed space or fire, otherwise there will be danger of trigger explosion and fire.
2, do not use the ethylene film to cause static things to cover the battery, sometimes the explosion is caused when static electricity is generated.
3, do not install the battery in a place where possible intake, otherwise there is a risk of electric shock and fire.
4, please do not install the battery in an environment of more than -40 ° C ~ 60 ° C.
5. Do not use the battery in a place with dust, 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 a sticky or label object to press the upper cover, because there is an exhaust valve below the upper cover, the gas generated in the battery will not exceed it.
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 is increased. In addition, when connected to the line, it is necessary to consider that the wire conductors and contact resistances between the columns are equal, 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 and old, when the battery is different, due to the difference in its characteristic value, the battery and machine may be damaged, so avoid use.
Fourth, about keeping
1. Please note that the temperature should not exceed -20 ° C ~ + 40 ° C in the range.
2. The battery must be kept in a fully charged state when the battery is kept. Replenish electricity due to the loss of the self-discharge due to the self-discharge during transport or during the storage period.
3, when long-term storage, for the self-discharge during the storage, please replenish the electricity. When kept in more than 40C, there is a bad influence on battery life, please avoid!
4, please keep in the dry low temperature and well ventilation.
5. If the battery pack is inadvertently wet during the storage or transfer process, the package should be immediately removed to avoid the wet carton that is wet, which is a conductor causes a battery discharge or a bad positive terminal.
V. About daily inspection and maintenance storage
1, regularly check the battery, if there is a surface contamination of dust, please clean the sheet with water or warm water. Do not clean with organic solvents such as gasoline, banana water or oil, and avoid using a chemical fiber cloth.
2. When the floating charge, the indicator value of the total voltage or indicator disk during the battery charging process is taken from the base value (± 0.05V / mononege "(± 0.05V / single).
