Introduce the 'memory effect' of nickel-metal hydride batteries and nickel-cadmium batteries

There are many types of laptop batteries, and the performance of different batteries will vary. Lithium batteries (or similar products) are now common in notebook computers. Not long ago, personal computers and A4 notebook computers temporarily used Ni-MH batteries. Before the mid-1990s, people used nickel-cadmium batteries. After purchasing a laptop, the user must first see the operating instructions to determine which battery is being used. If you don’t have an instruction manual, you can check the battery specifications on the manufacturer’s homepage. Ni-MH batteries and nickel-cadmium batteries have memory effect The biggest problem with nickel-hydrogen batteries and nickel-cadmium batteries is the memory effect. If the battery is not used up and charged (midway), the next time the battery is used, there will be no electricity in the place where the battery is charged. If this process is repeated over and over again, the battery life will become shorter and shorter. Although the memory effect of Ni-MH batteries is not as good as Ni-Cd batteries, repeated charging is also the reason for shortening the battery life, so please try to use up the battery before charging. Lithium batteries have no memory effect, so even intermittent charging is not a problem. Ways to extend battery life: Although lithium batteries have no memory effect, if they are used improperly, they will have a great impact on battery life. Pay attention to the following points when using lithium batteries: When the AC power supply|voltage regulator|voltage regulator is not used, it is more prone to aging when fully charged than incompletely charged. Especially when the AC drive is fully charged, it will bring a great burden to the battery. At the same time, heat loss is added, which further accelerates the aging of the battery. Therefore, it is best to use a battery to power the laptop once it is fully charged. The manufacturer recommends removing the battery when using AC power (however, if you remove the battery, you must be careful to lose unsaved data in the event of a power failure or unplugging the cable). The factor that affects battery life when using the power saving function is the number of times of charging and discharging. In order to reduce the number of charging, you can use the power-saving features of the laptop, such as dimming the screen and reducing the CPU speed to reduce battery power consumption. Similarly, when the battery is still being charged, it is best not to charge it to avoid draining the battery. Discharge completely every few months. Another trick is to completely discharge the battery every few months or so. The idea is to use the battery until it is zero, then stop using it, connect the AC adapter, and then not use your computer, just charge it. Some computers have a battery update function. If you think the battery is not good, you can try the battery discharge function. When not in use for a long time, please unplug the power plug. If it is not used for more than 8 hours, please unplug the power adapter to avoid burdening the battery. In addition, if you do not use it for more than a month, please remove the battery from the machine and place it in a cool place. When to replace the battery? The standard for replacing the battery is that it can only reach about 60% of the original capacity after charging. Since there are many types of batteries, you must buy one that you use on your computer. In addition, it's best not to buy a backup in advance, because even if you don't use it, the battery will naturally wear out. The current service does not purchase real batteries, but discharges the batteries currently in use to restore its performance. For example, BAYSUN can restore battery performance within a week. Not only is this cheaper than buying a genuine product, but it is also particularly convenient when the manufacturer does not have stock or the used laptop battery is no longer available.
