Frequently Asked Questions in the Quality of Battery

Battery's own quality performance may be due to the application of notgent, which will make the battery's real capacity, increased internal resistance, and even disorder, endanger UPS disordurbance and non-stop power. Above, suggest that several rare problems of the battery
Be
1, battery loss
Be
The battery is in the "lean" situation, its electrolyte is completely stored in the electrode and porous separation, once the battery is lost, its capacity is low, and when the amount of water is lost at 3.5 ml / Ah, the battery capacity will drop. 75% of the initial capacity is as follows, when water is lost 25%, the battery life will stop.
Be
Temperature battery application temperature, battery charging current and charging voltage, adopted all valve layouts and chooses the proper opening and closing valve pressure, adopts the bismuth plate alloy tips, low-grade hydrogen, improve the sealing and response efficacy, etc. to avoid battery loss is useful.
Be
2, battery cell deformation
Be
Once the battery housing is deformed, the polar can be rely, the electrolyte can not fully display, so that the battery internal resistance is increased, and the discharge capacity is reduced.
Be
The primary by the primary is the primary, if the external temperature of the battery is too high. In the application process, the battery should be controlled, and the charging current and charging voltage of the battery are maintained, and the battery is overcharged, and the superior ABS data and the proper device pressure are also very nervous.
Be
3, battery leakage
Be
The battery pole is presented to the latching image will cause the adapter wire to be corrupt, or the hunching resistance of the pole column and the adapter, which will also affect the remaining equipment of the power supply system.
Be
Battery leakage icon owner If the battery plan is lowered or the original data is not properly made. In order to avoid the production of the battery leakage, it should be improved in the originating process, adopted excellent pole column sealing rubber and ABS trough heat sealing techniques.
Be
4, battery capacity is not
Be
Because the battery quality is poor, its initial capacity can reach the plans rated value, but the capacity has been significantly low, and the capacity has dropped to 80% of the rated value. The reason for the formation of the battery capacity is quorning. This, the battery's own quality of the battery is:
Be
1) Delete deformation or breakage of the positive plate;
Be
2) The original data of the battery is set up or unqualified;
Be
3) The premise of the creation process is not strict;
Be
4) Positive electrode active material hardening and falling.
Be
Factors such as the application of the battery and the temperature of the battery are:
Be
1) The discharge rate is too large;
Be
2) The case is too low;
Be
3) The case temperature is low;
Be
4) Long-term storage aging;
Be
5) The charging parameter setting is not proper.
Be
In order to avoid the battery capacity to remove the application and protection, the advanced battery cream in the future, has been opened to adopt 4BS lead paste skills and non-bold plate alloy tips. 4BS lead paste skills can be useful to avoid low battery low capacity, while non-bismuth plate alloy tips can improve the interface layout between the grid and the active material, and the progress of the battery is charged.
Be
5, battery floating charge voltage average
Be
The difference in the average of the floating voltage of the single battery and the average of the unit of the unit should not be> 50mV, and the difference is the importance of the exquisite image of the floating voltage.
Be
In order to advance the battery floating charge voltage average, the error should be strictly controlled in the origin process.
Be
6, thermal out of control
Be
Battery application is not properly, so that the constant pressure charging era will present a critical condition. At this time, the charging current and temperature of the battery generate an interactive mutually enhanced sensation, and the light will deform the battery cell, extend battery life. Heavy people will also be safe in all power systems.
Be
The reason for the formation of thermal out of control is multi-faceted:
Be
1) Gas composite response in the outside of the battery (this self is hot and anti-ring) makes the battery temperature fall, which in turn has increased the floating current, and the gas rate accelerates, and the composite response is aggravated;
Be
2) The battery is "lean" and tight equipment layout plan, so that the outside of the battery is hard;
Be
3) The temperature of the battery is too high, at a higher temperature, the temperature is 1 degree per low, and the single battery voltage is less than 3mV, and the floating charge is in response to growth, so that the battery temperature is further low.
Be
7, exhaust valve take effect
Be

The exhaust valve has a problem when there is a problem, and the pressure of the battery cell is changed. When the valve pressure is increased, the battery slot is deformed. When the valve pressure is changed, the water loss is large, and the length will bring the average of the battery pack. Adverse effects.
