1 and the first 3-5 times of charging are generally called adjustment period, and should be charged for more than 14 hours to ensure the full activation of lithium ion activity. Also discharge, the method is to put it on the PDA handheld computer, and it will not work until it is automatically turned off. If the local network or location is very power-hungry, please take out the SIM card and open it until it is closed.
3. If the battery is still not up to standard, it may be that the charging current is not enough to fully activate the battery (commonly known as charging failure or insufficient charging), which may be caused by not using it for a long time or not fully activating it before leaving the factory. At this time, for friends, PDA PDA maintenance department applies to activate the battery (or add countercurrent activation); Friends who know electricity can also use DC constant voltage device to adjust the voltage to 5-6V and the current to 500-600mA, and connect the battery in reverse. Note: hair-trigger, repeat up to three times. After processing, use the original travel charger to charge during the adjustment period. Generally speaking, there should be no problem with the battery of PDA handheld computer after this treatment.
4. Depending on the type and capacity of the battery, the charging time of the battery is about 1.5-6 hours, which shall not exceed 24 hours.
5. The life of the battery depends on the number of times of repeated charging and discharging, so it is necessary to avoid charging the battery when the power is left, which will shorten the life of the battery. When the PDA handheld computer is turned off for more than 7 days, the battery of the PDA handheld computer should be completely discharged before use.
6. Nickel cadmium (NiCd) battery must be completely dead before charging and fully charged after charging.
In addition, from the point of view of environmental protection, the scrapped PDA handheld battery should be recycled, rather than littered. In foreign countries, the recycling of PDA pocket computer batteries must conform to the recycling plan made by the government and battery manufacturers. In China, there is a lack of battery recovery system for PDA handheld computers. Millions of PDA batteries are scrapped every year in China. If they are not recycled in time, it will cause long-term harm to the environment.
