With the development of science and technology, the backup battery market is becoming more and more extensive. In order not to affect the service life of the backup battery, we need to know some precautions about the use of the backup battery, and avoid the wrong use method to reduce the service life of the backup battery. Next, spare battery technical training personnel will briefly talk about the factors that affect the life of spare batteries.
1. Correlation between charging and discharging depth and battery charging frequency.
It can be seen from the data information obtained from the experiment that the battery charging frequency of the rechargeable battery is related to the battery charging depth. The heavier the battery charging depth is, the less the charging frequency of the rechargeable battery is. Filling frequency * charging and discharging depth = frequency within the total filling cycle time; the more frequency within the total filling cycle time, the more filling frequency * charging and discharging depth = specific service life of the rechargeable battery (ignoring other factors)
2, overcharging, power loss, and its large battery charging flow.
Do not charge the battery to cause overcharging, all a standby battery overcharging method will cause serious damage to the battery performance, and even cause the characteristics of the reduction. Do not charge or discharge below 2V or deep, as this will quickly destroy the backup battery. Internal metal plating is likely to occur, resulting in short circuit failure, resulting in rechargeable batteries can not be used or unsafe.
Most backup batteries have an electronic circuit inside the rechargeable battery that will disconnect the rechargeable battery connection when the battery is being charged or discharged, when the battery voltage is below, above, or when the rechargeable battery flow exceeds a predetermined threshold. It is not necessary to use high-current batteries for charging and discharging, as high current will cause excessive working pressure on rechargeable batteries.
3, natural environment over temperature or low temperature.
The life of the spare battery is also affected by the temperature. Natural environments with temperatures below zero can damage lithium batteries when electronics are started, while natural environments with temperatures above zero can reduce the volume of rechargeable batteries. Therefore, if the laptop long-term application of external power supply did not take out the rechargeable battery, rechargeable battery is long-term in the notebook discharge of high heat, will quickly be eliminated.
4, long-term full grid, no power situation.
Too much or too little power in the backup battery will harm the number of battery cycles. Most of the market sales of household appliances or rechargeable batteries marked on the repeatable battery charging frequency, to charge and discharge 80% as the standard detection. The experimental results show that for the lithium battery of some notebooks, the working voltage of the rechargeable battery often exceeds the standard working voltage amperes, that is, the service life of the rechargeable battery will decline when the amperes are increased, and then the service life will be reduced by 1/3 when the amperes are increased. The larger the charge, the greater the drain on the rechargeable battery. For a long time in the low or no power situation, the internal friction resistance of the rechargeable battery to the electronic devices will become greater and greater, resulting in the reduction of battery power.
