How to use Ni-MH batteries correctly?

1. Under normal circumstances, the new Ni-MH battery only contains a small amount of electricity. You must charge it before using it after purchase. However, if the battery leaves the factory for a short time and has sufficient power, it is recommended to use it first and then recharge it. 2. The performance of newly-purchased nickel-metal hydride batteries generally needs to be charged and used 3-4 times to achieve the best performance. Many friends have small problems with the first charge, such as the number of PP after the first charge. Imagine so much? It was solved after 3-4 times of charging and use. 3. Although the memory effect of Ni-MH batteries is small, it is still recommended that everyone try to charge them after each use, and charge them all at once. Do not charge them for a while and then use them for a while. This is an important point for longevity. 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 too many debris should be placed around the charger. Ordinary users often do not have a dedicated storage bag for the battery when using the battery; after replacing the battery, the user will habitually put the battery away, regardless of whether the place is clean or humid. The consequence of this is that the battery is easy to get dirty, the contacts are easy to contact with metals such as keys, etc., and they are easy to get damp, and these are the enemies of the battery. Suggestion: The user should set a dedicated battery placement point and keep the battery clean. In order to prevent problems such as power loss, keep the contact points at both ends of the battery and the inside of the battery cover clean, and wipe gently with a soft, clean, dry cloth if necessary. 5. When not in use for a long time, remember to take the battery out of the battery compartment and place it in a dry environment. It is recommended to put it in a branded battery box to prevent battery short circuit. 6. Ni-MH batteries that have not been used for a long time will naturally enter a dormant state after being stored for a few months, and the battery life will be greatly reduced. If the Ni-MH battery has been stored for a long time, it is advisable to charge it with a slow charge first. Here comes another key question: Regarding Ni-MH batteries, should the batteries be stored after being fully discharged, or should they be stored with electricity? Which of these two very different views should be adopted? Many people think that the former should be used, but the author thinks that it is more reasonable to keep the battery charged. Because: According to the test, the best condition for storage of Ni-MH batteries is about 80% charged storage. This is because the self-discharge of Ni-MH battery is relatively large (about 10%-15% a month). If the battery is completely discharged and then stored and not used for a long time, the self-discharge of the battery will cause the battery to over-discharge. It will damage the battery. Do not believe? Then think about whether the newly-purchased Ni-MH rechargeable batteries still have electricity. This is the reason. Suggestion: compare more, correct the wrong point of view, and start maintaining the battery from the right direction, otherwise it will be counterproductive. 7. Many friends have posted inquiries about how to discharge Ni-MH? After asking many battery experts, I came to a consistent conclusion to remind my friends. Try not to discharge the Ni-MH battery, over-discharging will cause charging failure, the harm of doing so is far greater than the memory effect of the Ni-MH battery itself! 8. The multimeter self-checks whether the battery is full or not. Generally, the voltage of the Ni-MH battery is below 1.2V before charging, and the normal voltage is around 1.4V after being fully charged. With this judgment, it is easy to judge the state of the battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
