Maintenance and use of Ni MH battery
2020-09-12
1. In general, the new Ni MH battery only contains a small amount of electricity. You should charge it before using it after you buy it. However, if the battery factory time is short and the battery is full, it is recommended to use it first and then charge it.
2. Generally, the newly purchased Ni MH battery needs to be charged and used for 3-4 times in order to give full play to its performance. Many friends encounter minor problems during the first charging, for example, the number of films taken after the first charge is not as much as expected. After 3-4 times of charging and using, it can be easily solved.
3. Although the memory effect of Ni MH battery is small, it is still recommended that the battery be recharged after each use, and it should be fully charged at one time. Do not charge it for a while and then charge it again. This is an important point of "prolonging life".
4. When charging the battery, pay attention to the heat dissipation around the charger. It is not necessary to use any fan to blow it too deliberately, but it should be noted that there are not too many sundries around the charger. Ordinary users in the process of using the battery, the battery often does not have a special storage bag; after replacing the battery, the user will habitually put the battery away, regardless of whether the place is clean and humid. The result is that the battery is easy to get dirty, the contacts are easy to contact with metal, such as keys, etc., which are the enemies of batteries. Suggestion: users should set up a special battery storage point and keep the battery clean. In order to avoid power loss and other problems, keep the contact points at both ends of the battery and the inside of the battery cover clean, if necessary, use a soft, clean dry cloth to wipe.
5. When it is not used for a long time, remember to take the battery out of the battery compartment and put it in a dry environment. It is recommended to put it into a brand-name battery box to avoid battery short-circuit.
6. The Ni MH battery that has not been used for a long time will naturally enter a "dormant" state after being stored for several months, and the battery life will be greatly reduced. If the Ni MH battery has been placed for a long time, it is recommended that you charge it slowly. According to the test, the best storage condition of Ni MH battery is about 80% charged. This is because the self discharge of Ni MH battery is large (about 10% - 15% in a month). If the battery is completely discharged and stored, and it is not used for a long time, the self discharge phenomenon of the battery will cause the battery over discharge and damage the battery. Don't believe it? Then you want to think about whether the newly purchased Ni MH rechargeable batteries still have electricity, which is the truth. Suggestion: compare more, correct the wrong point of view, start from the right direction to maintain the battery, otherwise it will be contrary to our wishes.
7. Discharge nickel hydride. Expert advice. Try not to discharge Ni MH battery, over discharge will lead to charging failure, the harm of doing so is far greater than the memory effect of Ni MH battery itself!
8. The multimeter checks whether the battery is full or not. Generally, the voltage of Ni MH battery is below 1.2V before charging and about 1.4V after full charging. If you judge by this, it is easy to judge the state of the battery.
9. Chargers are mainly divided into fast charging and slow charging. The slow charging current is small, usually about 200mA. For example, our common charging current is about 160mA. Her charging time is long, and it takes about 16 hours to charge a 1800mAh Ni MH battery. Although the time is slow, but the charging will be very sufficient, and does not damage the battery. The fast charging current is usually more than 400mA, and the charging time is significantly reduced. It can be done in 3-4 hours, which has won the love of everyone. There are many kinds of fast charging, and the prices are different. As a result, we often wonder why there is a big difference in the price of fast charging? Good chargers, especially good fast charging, are equipped with anti overcharge protection function. For example, our common Panasonic premium charger bq390 performs particularly well in this respect. Excellent chip software design ability can also minimize the damage of fast charging to the battery when charging the battery.
10. Contradiction: slow charging does not damage the battery, but the charging time is too long; fast charging can save time, but it is harmful to the battery. Even the best Panasonic charger bq390 in the world can only reduce the degree of damage, but can not be completely avoided. The solution is to buy a fast charge and a slow charge. Use fast charging for a period of time, for example, after 5 or 10 times, switch to slow charging once or twice. This Ni MH battery
This will restore the performance of the battery to its best state.
11. Batteries are usually used as battery packs, that is, 4 or 6 batteries are connected in series. At this time, it is very important to keep the balance of each battery. Otherwise, the work of the whole battery pack will be affected due to the problem of one of the batteries. First of all, to ensure that the battery capacity is consistent, it is best to choose the same brand and the same model of batteries purchased at the same time. Then, to keep the battery internal power consistent, simply put, the battery pack is either full or empty. If you have more batteries to make up a number of batteries, you can try to "select" them. Specifically, the cells with similar capacity and voltage parameters are connected in series to form a group of batteries. Due to the lack of conditions, it is generally enough to measure the voltage after lowering the point and the voltage after charging.
12. Finally, charge and discharge. High grade Ni-MH charger uses - DeltaV to detect the battery voltage to determine whether the battery is full. The voltage curve of the battery during charging is similar to that of discharging. At first, it rises rapidly, then rises slowly. When the battery is fully charged, the voltage begins to rise rapidly again
